Since 4.20menu_Text for an item in the context menu to activate the primary icon action.
When the primary icon is activatable and this property has been set, a new entry in the context menu of this GtkEntry will appear with this text. Selecting that menu entry will result in the primary icon being activated, exactly in the same way as it would be activated from a mouse click.
This simplifies adding accessibility support to applications using activatable icons. The activatable icons aren't focusable when navigating the interface with the keyboard This is why Gtk recommends to also add those actions in the context menu. This set of methods greatly simplifies this, by adding a menu item that, when enabled, calls the same callback than clicking on the icon.

Activates the widget.
The activation will emit the signal set using Gtk.WidgetClass.set_activate_signal during class initialization.
Activation is what happens when you press Enter on a widget.
If you wish to handle the activation keybinding yourself, it is recommended to use Gtk.WidgetClass.add_shortcut with an action created with Gtk.SignalAction.new.
If widget is not activatable, the function returns false.
true if the widget was activated
Activates an action for the widget.
The action is looked up in the action groups associated with
widget and its ancestors.
If the action is in an action group added with
Gtk.Widget.insert_action_group, the name is expected
to be prefixed with the prefix that was used when the group was
inserted.
The arguments must match the actions expected parameter type, as returned by Gio.Action.get_parameter_type.

Activates the default.activate action for the widget.
The action is looked up in the same was as for Gtk.Widget.activate_action.
Adds an event controller to the widget.
The event controllers of a widget handle the events that are propagated to the widget.
You will usually want to call this function right after creating any kind of Gtk.EventController.

Adds a style class to the widget.
After calling this function, the widget’s style will match
for css_class, according to CSS matching rules.
Use Gtk.Widget.remove_css_class to remove the style again.

Adds a widget to the list of mnemonic labels for this widget.
See Gtk.Widget.list_mnemonic_labels.
Note that the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well.
Queues an animation frame update and adds a callback to be called before each frame.
Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames.
The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a label), then you will have to call Gtk.Widget.queue_resize or Gtk.Widget.queue_draw yourself.
Gdk.FrameClock.get_frame_time should generally be used for timing continuous animations and Gdk.FrameTimings.get_predicted_presentation_time should be used if you are trying to display isolated frames at particular times.
This is a more convenient alternative to connecting directly to the
Gdk.FrameClock::update signal of the frame clock, since you
don't have to worry about when a frame clock is assigned to a widget.
To remove a tick callback, pass the ID that is returned by this function to Gtk.Widget.remove_tick_callback.

Assigns size, position, (optionally) a baseline and transform to a child widget.
In this function, the allocation and baseline may be adjusted. The given allocation will be forced to be bigger than the widget's minimum size, as well as at least 0×0 in size.
This function is only used by widget implementations.
For a version that does not take a transform, see Gtk.Widget.size_allocate.

Requests the user's screen reader to announce the given message.
This kind of notification is useful for messages that either have only a visual representation or that are not exposed visually at all, e.g. a notification about a successful operation.
Also, by using this API, you can ensure that the message does not interrupts the user's current screen reader output.

Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget GObject.Object instance to be updated with the same value of the "active" property of the action GObject.Object instance.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
GObject.Binding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A GObject.Object can have multiple bindings.

the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.
Complete version of g_object_bind_property().
Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.
If flags contains GObject.BindingFlags.BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well. The transform_from function is only used in case
of bidirectional bindings, otherwise it will be ignored
The binding will automatically be removed when either the source or the
target instances are finalized. This will release the reference that is
being held on the GObject.Binding instance; if you want to hold on to the
GObject.Binding instance, you will need to hold a reference to it.
To remove the binding, call g_binding_unbind().
A GObject.Object can have multiple bindings.
The same user_data parameter will be used for both transform_to
and transform_from transformation functions; the notify function will
be called once, when the binding is removed. If you need different data
for each transformation function, please use
g_object_bind_property_with_closures() instead.

Optionaltransform_from: BindingTransformFuncthe transformation function from the target to the source, or null to use the default
Optionalnotify: DestroyNotifya function to call when disposing the binding, to free resources used by the transformation functions, or null if not required
the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.
Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.
This function is the language bindings friendly version of
g_object_bind_property_full(), using GClosures instead of
function pointers.

the GObject.Binding instance representing the binding between the two GObject.Object instances. The binding is released whenever the GObject.Binding reference count reaches zero.
Blocks a handler of an instance so it will not be called during any signal emissions
Handler ID of the handler to be blocked
Called by widgets as the user moves around the window using keyboard shortcuts.
The direction argument indicates what kind of motion is taking
place (up, down, left, right, tab forward, tab backward).
This function calls the Gtk.Widget.focus virtual function; widgets can override the virtual function in order to implement appropriate focus behavior.
The default focus() virtual function for a widget should return
true if moving in direction left the focus on a focusable location
inside that widget, and false if moving in direction moved the focus
outside the widget. When returning true, widgets normally call
Gtk.Widget.grab_focus to place the focus accordingly;
when returning false, they don’t modify the current focus location.
This function is used by custom widget implementations; if you're writing an app, you’d use Gtk.Widget.grab_focus to move the focus to a particular widget.
direction of focus movement
true if focus ended up inside widget
Computes the bounds for widget in the coordinate space of target.
The bounds of widget are (the bounding box of) the region that it is expected to draw in. See the coordinate system overview to learn more.
If the operation is successful, true is returned. If widget has no
bounds or the bounds cannot be expressed in target's coordinate space
(for example if both widgets are in different windows), false is
returned and bounds is set to the zero rectangle.
It is valid for widget and target to be the same widget.
true if the bounds could be computed
Computes whether a parent widget should give this widget extra space when possible.
Widgets with children should check this, rather than looking at Gtk.Widget.get_hexpand or Gtk.Widget.get_vexpand.
This function already checks whether the widget is visible, so visibility does not need to be checked separately. Non-visible widgets are not expanded.
The computed expand value uses either the expand setting explicitly set on the widget itself, or, if none has been explicitly set, the widget may expand if some of its children do.
expand direction
whether widget tree rooted here should be expanded
Translates the given point in widget's coordinates to coordinates
in target’s coordinate system.
In order to perform this operation, both widgets must share a
a common ancestor. If that is not the case, out_point is set
to (0, 0) and false is returned.
true if src_widget and dest_widget have a common ancestor, false otherwise
Computes a matrix suitable to describe a transformation from
widget's coordinate system into target's coordinate system.
The transform can not be computed in certain cases, for example
when widget and target do not share a common ancestor. In that
case out_transform gets set to the identity matrix.
To learn more about widget coordinate systems, see the coordinate system overview.
true if the transform could be computed
SignalconnectSignalconnect_Tests if a given point is contained in the widget.
The coordinates for (x, y) must be in widget coordinates, so
(0, 0) is assumed to be the top left of widget's content area.
X coordinate to test, relative to widget's origin
Y coordinate to test, relative to widget's origin
true if widget contains the point (x, y)
Creates a new Pango.Context that is configured for the widget.
The Pango.Context will have the appropriate font map, font options, font description, and base direction set.
See also Gtk.Widget.get_pango_context.
the new Pango.Context
Creates a new Pango.Layout that is configured for the widget.
The Pango.Layout will have the appropriate font map, font description, and base direction set.
If you keep a Pango.Layout created in this way around, you need to re-create it when the widgets Pango.Context is replaced. This can be tracked by listening to changes of the Gtk.Widget.root property on the widget.
Optionaltext: stringtext to set on the layout
the new Pango.Layout
Retrieves the accessible platform state from the editable delegate.
This is an helper function to retrieve the accessible state for Gtk.Editable interface implementations using a delegate pattern.
You should call this function in your editable widget implementation of the Gtk.Accessible.get_platform_state virtual function, for instance:
static void
accessible_interface_init (GtkAccessibleInterface *iface)
{
iface->get_platform_state = your_editable_get_accessible_platform_state;
}
static gboolean
your_editable_get_accessible_platform_state (GtkAccessible *accessible,
GtkAccessiblePlatformState state)
{
return gtk_editable_delegate_get_accessible_platform_state (GTK_EDITABLE (accessible), state);
}
Note that the widget which is the delegate must be a direct child of this widget, otherwise your implementation of Gtk.Accessible.get_platform_state might not even be called, as the platform change will originate from the parent of the delegate, and, as a result, will not work properly.
So, if you can't ensure the direct child condition, you should give the delegate the Gtk.AccessibleRole.TEXT_BOX role, or you can change your tree to allow this function to work.
what kind of accessible state to retrieve
the accessible platform state of the delegate
Deletes the currently selected text of the editable.
This call doesn’t do anything if there is no selected text.
Deletes a sequence of characters.
The characters that are deleted are those characters at positions
from start_pos up to, but not including end_pos. If end_pos is
negative, then the characters deleted are those from start_pos to
the end of the text.
Note that the positions are specified in characters, not bytes.
start position
end position
Disconnects a handler from an instance so it will not be called during any future or currently ongoing emissions of the signal it has been connected to.
Handler ID of the handler to be disconnected
Clears the template children for the widget.
This function is the opposite of Gtk.Widget.init_template,
and it is used to clear all the template children from a widget
instance. If you bound a template child to a field in the instance
structure, or in the instance private data structure, the field will
be set to NULL after this function returns.
You should call this function inside the GObject.Object.dispose implementation of any widget that called Gtk.Widget.init_template. Typically, you will want to call this function last, right before chaining up to the parent type's dispose implementation, e.g.
static void
some_widget_dispose (GObject *gobject)
{
SomeWidget *self = SOME_WIDGET (gobject);
// Clear the template data for SomeWidget
gtk_widget_dispose_template (GTK_WIDGET (self), SOME_TYPE_WIDGET);
G_OBJECT_CLASS (some_widget_parent_class)->dispose (gobject);
}
the type of the widget to finalize the template for
Checks to see if a drag movement has passed the GTK drag threshold.
X coordinate of start of drag
Y coordinate of start of drag
current X coordinate
current Y coordinate
true if the drag threshold has been passed
Emits the Gtk.CellEditable::editing-done signal.
SignalemitNotifies the user about an input-related error on the widget.
If the Gtk.Settings.gtk_error_bell setting is true, it calls Gdk.Surface.beep, otherwise it does nothing.
Note that the effect of Gdk.Surface.beep can be configured in many ways, depending on the windowing backend and the desktop environment or window manager that is used.
Undoes the setup done by Gtk.Editable.init_delegate.
This is a helper function that should be called from dispose, before removing the delegate object.
This function is intended for GObject.Object implementations to re-enforce
a [floating][floating-ref] object reference. Doing this is seldom
required: all GInitiallyUnowneds are created with a floating reference
which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
GObject.Object::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Retrieves the accessible parent for an accessible object.
This function returns NULL for top level widgets.
the accessible parent
Retrieves the accessible role of an accessible object.
the accessible role
Retrieves the value set by gtk_entry_set_activates_default().
true if the entry will activate the default widget
Gets the value set by gtk_entry_set_alignment().
See also: Gtk.Editable.xalign
the alignment
Returns the baseline that has currently been allocated to the widget.
This function is intended to be used when implementing handlers for the Gtk.Widget.snapshot function, and when allocating child widgets in Gtk.Widget.size_allocate.
the baseline of the widget, or -1 if none
Returns the height that has currently been allocated to the widget.
To learn more about widget sizes, see the coordinate system overview.
the height of the widget
Returns the width that has currently been allocated to the widget.
To learn more about widget sizes, see the coordinate system overview.
the width of the widget
Retrieves the widget’s allocation.
Note, when implementing a layout widget: a widget’s allocation will be its “adjusted” allocation, that is, the widget’s parent typically calls Gtk.Widget.size_allocate with an allocation, and that allocation is then adjusted (to handle margin and alignment for example) before assignment to the widget. Gtk.Widget.get_allocation returns the adjusted allocation that was actually assigned to the widget. The adjusted allocation is guaranteed to be completely contained within the Gtk.Widget.size_allocate allocation, however.
So a layout widget is guaranteed that its children stay inside the assigned bounds, but not that they have exactly the bounds the widget assigned.
Gets the first ancestor of the widget with type widget_type.
For example, gtk_widget_get_ancestor (widget, GTK_TYPE_BOX)
gets the first Gtk.Box that’s an ancestor of widget. No
reference will be added to the returned widget; it should
not be unreferenced.
Note that unlike Gtk.Widget.is_ancestor, this function
considers widget to be an ancestor of itself.
ancestor type
the ancestor widget
Returns the baseline that has currently been allocated to the widget.
This function is intended to be used when implementing handlers for the Gtk.Widget.snapshot function, and when allocating child widgets in Gtk.Widget.size_allocate.

Determines whether the input focus can enter the widget or any of its children.
true if the input focus can enter widget
Queries whether the widget can be the target of pointer events.
true if widget can receive pointer events
Retrieves a sequence of characters.
The characters that are retrieved are those characters at positions
from start_pos up to, but not including end_pos. If end_pos is negative,
then the characters retrieved are those characters from start_pos to
the end of the text.
Note that positions are specified in characters, not bytes.
start of text
end of text
a pointer to the contents of the widget as a string. This string is allocated by the Gtk.Editable implementation and should be freed by the caller.
Gets the value set with Gtk.Widget.set_child_visible.
If you feel a need to use this function, your code probably needs reorganization.
This function is only useful for widget implementations and should never be called by an application.
true if the widget is mapped with the parent
Returns the auxiliary completion object currently
in use by entry.
The auxiliary completion object currently in use by entry
Returns the list of style classes applied to the widget.
a NULL-terminated list of css classes currently applied to widget

Gets the Gtk.Editable that editable is delegating its
implementation to.
Typically, the delegate is a Gtk.Text widget.
the delegate Gtk.Editable
Gets the reading direction for the widget.
the reading direction for the widget
Get the display for the window that the widget belongs to.
This function can only be called after the widget has been added to a widget hierarchy with a Gtk.Root at the top.
In general, you should only create display-specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.
the display for this widget
Retrieves whether editable is editable.
true if editable is editable.
Gets if undo/redo actions are enabled for editable
true if undo is enabled
Retrieves the first accessible child of an accessible object.

Determines whether the widget can own the input focus.
true if widget can own the input focus
Returns the cairo_font_options_t of the widget.
the cairo_font_options_t of widget
Obtains the frame clock for a widget.
The frame clock is a global “ticker” that can be used to drive animations and repaints. The most common reason to get the frame clock is to call Gdk.FrameClock.get_frame_time, in order to get a time to use for animating. For example you might record the start of the animation with an initial value from Gdk.FrameClock.get_frame_time, and then update the animation by calling Gdk.FrameClock.get_frame_time again during each repaint.
Gdk.FrameClock.request_phase will result in a new frame on the clock, but won’t necessarily repaint any widgets. To repaint a widget, you have to use Gtk.Widget.queue_draw which invalidates the widget (thus scheduling it to receive a draw on the next frame). Gtk.Widget.queue_draw will also end up requesting a frame on the appropriate frame clock.
A widget’s frame clock will not change while the widget is mapped. Reparenting a widget (which implies a temporary unmap) can change the widget’s frame clock.
Unrealized widgets do not have a frame clock.
the frame clock
Gets the horizontal alignment of the widget.
For backwards compatibility reasons this method will never return one of the baseline alignments, but instead it will convert it to Gtk.Align.FILL or Gtk.Align.CENTER.
Baselines are not supported for horizontal alignment.
the horizontal alignment of widget
Gets the value set by gtk_entry_set_has_frame().
whether the entry has a beveled frame
Returns the current value of the has-tooltip property.
current value of has-tooltip on widget
Returns the content height of the widget.
This function returns the height passed to its size-allocate implementation, which is the height you should be using in Gtk.Widget.snapshot.
For pointer events, see Gtk.Widget.contains.
To learn more about widget sizes, see the coordinate system overview.
The height of widget
Gets whether the widget would like any available extra horizontal space.
When a user resizes a window, widgets with expand set to true generally receive the extra space. For example, a list or scrollable area or document in your window would often be set to expand.
Widgets with children should use Gtk.Widget.compute_expand rather than this function, to see whether any of its children, has the expand flag set. If any child of a widget wants to expand, the parent may ask to expand also.
This function only looks at the widget’s own hexpand flag, rather than computing whether the entire widget tree rooted at this widget wants to expand.
whether hexpand flag is set
Gets whether the hexpand flag has been explicitly set.
If Gtk.Widget.hexpand property is set, then it
overrides any computed expand value based on child widgets.
If hexpand is not set, then the expand value depends on
whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.
whether hexpand has been explicitly set
Returns whether the icon is activatable.
Icon position
true if the icon is activatable.
Gets the area where entry’s icon at icon_pos is drawn.
This function is useful when drawing something to the entry in a draw callback.
If the entry is not realized or has no icon at the given
position, icon_area is filled with zeros. Otherwise,
icon_area will be filled with the icon's allocation,
relative to entry's allocation.
Icon position
Finds the icon at the given position and return its index.
The position’s coordinates are relative to the entry’s
top left corner. If x, y doesn’t lie inside an icon,
-1 is returned. This function is intended for use in a
Gtk.Widget::query-tooltip signal handler.
the x coordinate of the position to find, relative to entry
the y coordinate of the position to find, relative to entry
the index of the icon at the given position, or -1
Retrieves the Gio.Icon used for the icon.
null will be returned if there is no icon or if the icon was
set by some other method (e.g., by Gdk.Paintable or icon name).

Retrieves the Gdk.Paintable used for the icon.
If no Gdk.Paintable was used for the icon, null is returned.
Icon position
A Gdk.Paintable if no icon is set for this position or the icon set is not a Gdk.Paintable.
Returns whether the icon appears sensitive or insensitive.
Icon position
true if the icon is sensitive.
Gets the type of representation being used by the icon to store image data.
If the icon has no image data, the return value will be Gtk.ImageType.EMPTY.

Retrieves the desired maximum width of editable, in characters.
the maximum width of the entry, in characters
Gets the text that will be used in the context menu of the Gtk.Entry when the specified icon is activatable. Selecting this item in the menu results, from all aspects, the same than clicking on the specified icon. This greatly simplifies making accessible applications, because the icons aren't focusable when using keyboard navigation. This is why Gtk recommends to add the same action to the context menu.
either GTK_ENTRY_ICON_PRIMARY or GTK_ENTRY_ICON_SECONDARY
the text that will be used in the menu item, or NULL if no menu item is desired.
Retrieves the name of a widget.
See Gtk.Widget.set_name for the significance of widget names.

Returns the nearest Gtk.Native ancestor of the widget.
This function will return NULL if the widget is not
contained inside a widget tree with a native ancestor.
Gtk.Native widgets will return themselves here.

Retrieves the next accessible sibling of an accessible object
the next accessible sibling
Fetches the requested opacity for the widget.
the requested opacity for this widget
Gets whether the Gtk.Entry is in overwrite mode.
whether the text is overwritten when typing.
Gets a Pango.Context that is configured for the widget.
The Pango.Context will have the appropriate font map, font description, and base direction set.
Unlike the context returned by Gtk.Widget.create_pango_context, this context is owned by the widget (it can be used until the screen for the widget changes or the widget is removed from its toplevel), and will be updated to match any changes to the widget’s attributes. This can be tracked by listening to changes of the Gtk.Widget.root property on the widget.
the Pango.Context for the widget
Retrieves the text that will be displayed when entry
is empty and unfocused
a pointer to the placeholder text as a string. This string points to internally allocated storage in the widget and must not be freed, modified or stored. If no placeholder text has been set, null will be returned.
Queries a platform state, such as focus.
This functionality can be overridden by Gtk.Accessible implementations, e.g. to get platform state from an ignored child widget, as is the case for Gtk.Text wrappers.
platform state to query
the value of state for the accessible
Retrieves the current position of the cursor relative to the start of the content of the editable.
Note that this position is in characters, not in bytes.
the cursor position
Retrieves the minimum and natural size of a widget, taking into account the widget’s preference for height-for-width management.
This is used to retrieve a suitable size by container widgets which do not impose any restrictions on the child placement. It can be used to deduce toplevel window and menu sizes as well as child widgets in free-form containers such as Gtk.Fixed.
Handle with care. Note that the natural height of a height-for-width widget will generally be a smaller size than the minimum height, since the required height for the natural width is generally smaller than the required height for the minimum width.
Use Gtk.Widget.measure if you want to support baseline alignment.
Returns the current fraction of the task that’s been completed.
a fraction from 0.0 to 1.0
Retrieves the pulse step set with
gtk_entry_set_progress_pulse_step().
a fraction from 0.0 to 1.0
Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling GObject.Value.unset.
Note that GObject.Object.get_property is really intended for language bindings, GObject.Object.get is much more convenient for C programming.
The name of the property to get
Return location for the property value. Can be an empty GObject.Value initialized by G_VALUE_INIT (auto-initialized with expected type since GLib 2.60), a GObject.Value initialized with the expected property type, or a GObject.Value initialized with a transformable type
This function gets back user data pointers stored via
g_object_set_qdata().
A GLib.Quark, naming the user data pointer
The user data pointer set, or null
Determines whether the widget is realized.
true if widget is realized
Determines whether the widget is always treated as the default widget within its toplevel when it has the focus, even if another widget is the default.
true if widget acts as the default widget when focused
Gets whether the widget prefers a height-for-width layout or a width-for-height layout.
Single-child widgets generally propagate the preference of their child, more complex widgets need to request something either in context of their children or in context of their allocation capabilities.
The Gtk.SizeRequestMode preferred by widget.
Retrieves the internal scale factor that maps from window coordinates to the actual device pixels.
On traditional systems this is 1, on high density outputs, it can be a higher value (typically 2).
See Gdk.Surface.get_scale_factor.
Note that modern systems may support fractional scaling, where the scale factor is not an integer. On such systems, this function will return the next higher integer value, but you probably want to use Gdk.Surface.get_scale to get the fractional scale value.
the scale factor for widget
Retrieves the selection bound of the editable.
start_pos will be filled with the start of the selection and
end_pos with end. If no text was selected both will be identical
and false will be returned.
Note that positions are specified in characters, not bytes.
true if there is a non-empty selection, false otherwise
Returns the widget’s sensitivity.
This function returns the value that has been set using Gtk.Widget.set_sensitive).
The effective sensitivity of a widget is however determined by both its own and its parent widget’s sensitivity. See Gtk.Widget.is_sensitive.
true if the widget is sensitive
Gets the settings object holding the settings used for the widget.
Note that this function can only be called when the Gtk.Widget
is attached to a toplevel, since the settings object is specific
to a particular display. If you want to monitor the widget for
changes in its settings, connect to the notify::display signal.
the relevant settings object
Returns the content width or height of the widget.
Which dimension is returned depends on orientation.
This is equivalent to calling Gtk.Widget.get_width for Gtk.Orientation.HORIZONTAL or Gtk.Widget.get_height for Gtk.Orientation.VERTICAL, but can be used when writing orientation-independent code, such as when implementing Gtk.Orientable widgets.
To learn more about widget sizes, see the coordinate system overview.
the orientation to query
the size of widget in orientation
Gets the size request that was explicitly set for the widget.
A value of -1 stored in width or height indicates that that
dimension has not been set explicitly and the natural requisition
of the widget will be used instead.
See Gtk.Widget.set_size_request.
To get the size a widget will actually request, call Gtk.Widget.measure instead of this function.
Returns the widget state as a flag set.
It is worth mentioning that the effective Gtk.StateFlags.INSENSITIVE
state will be returned, that is, also based on parent insensitivity,
even if widget itself is sensitive.
Also note that if you are looking for a way to obtain the Gtk.StateFlags to pass to a Gtk.StyleContext method, you should look at Gtk.StyleContext.get_state.
the state flags of widget
Returns the style context associated to the widget.
The returned object is guaranteed to be the same
for the lifetime of widget.
the widgets style context
Fetches an object build from the template XML for widget_type in
the widget.
This will only report children which were previously declared with Gtk.WidgetClass.bind_template_child_full or one of its variants.
This function is only meant to be called for code which is private
to the widget_type which declared the child and is meant for language
bindings which cannot easily make use of the GObject structure offsets.
The GObject.GType to get a template child for
ID of the child defined in the template XML
the object built in the template XML with the id name
Retrieves the contents of editable.
The returned string is owned by GTK and must not be modified or freed.

Retrieves the current length of the text in entry.
This is equivalent to getting entry's Gtk.EntryBuffer
and calling Gtk.EntryBuffer.get_length on it.
the current number of characters in Gtk.Entry, or 0 if there are none.
Gets the contents of the tooltip for the widget.
If the tooltip has not been set using
Gtk.Widget.set_tooltip_markup, this
function returns NULL.
the tooltip text
Gets the contents of the tooltip for the widget.
If the widget's tooltip was set using
Gtk.Widget.set_tooltip_markup,
this function will return the escaped text.
the tooltip text
Gets whether the widget would like any available extra vertical space.
See Gtk.Widget.get_hexpand for more detail.
whether vexpand flag is set
Gets whether the vexpand flag has been explicitly set.
See Gtk.Widget.get_hexpand_set for more detail.
whether vexpand has been explicitly set
Retrieves whether the text in entry is visible.
true if the text is currently visible
Determines whether the widget is visible.
If you want to take into account whether the widget’s parent is also marked as visible, use Gtk.Widget.is_visible instead.
This function does not check if the widget is obscured in any way.
true if the widget is visible
Returns the content width of the widget.
This function returns the width passed to its size-allocate implementation, which is the width you should be using in Gtk.Widget.snapshot.
For pointer events, see Gtk.Widget.contains.
To learn more about widget sizes, see the coordinate system overview.
The width of widget
Gets the number of characters of space reserved for the contents of the editable.
number of chars to request space for, or negative if unset
Gets n_properties properties for an object.
Obtained properties will be set to values. All properties must be valid.
Warnings will be emitted and undefined behaviour may result if invalid
properties are passed in.

the values of each property to get
Causes widget to have the keyboard focus for the window
that it belongs to.
If widget is not focusable, or its Gtk.Widget.grab_focus
implementation cannot transfer the focus to a descendant of widget
that is focusable, it will not take focus and false will be returned.
Calling Gtk.Widget.grab_focus on an already focused widget is allowed, should not have an effect, and return true.
true if focus is now inside widget
Causes entry to have keyboard focus.
It behaves like Gtk.Widget.grab_focus, except that it doesn't select the contents of the entry. You only want to call this on some special entries which the user usually doesn't want to replace all text in, such as search-as-you-type entries.
true if focus is now inside self
Returns whether a style class is currently applied to the widget.
style class, without the leading period
true if css_class is currently applied to widget
Determines if the widget should show a visible indication that it has the global input focus.
This is a convenience function that takes into account whether
focus indication should currently be shown in the toplevel window
of widget. See Gtk.Window.get_focus_visible for more
information about focus indication.
To find out if the widget has the global input focus, use Gtk.Widget.has_focus.
true if the widget should display a “focus rectangle”
Reverses the effects of [method.Gtk.Widget.show].
This is causing the widget to be hidden (invisible to the user).
Returns whether the widget is currently being destroyed.
This information can sometimes be used to avoid doing unnecessary work.
true if widget is being destroyed
Sets up a delegate for Gtk.Editable.
This is assuming that the get_delegate vfunc in the Gtk.Editable
interface has been set up for the editable's type.
This is a helper function that should be called in instance init, after creating the delegate object.
Creates and initializes child widgets defined in templates.
This function must be called in the instance initializer for any class which assigned itself a template using Gtk.WidgetClass.set_template.
It is important to call this function in the instance initializer
of a widget subclass and not in GObject.constructed() or
GObject.constructor() for two reasons:
g_object_new() on a widget with composite templates,
it’s important to build the composite widgets before the construct
properties are set. Properties passed to g_object_new() should
take precedence over properties set in the private template XMLA good rule of thumb is to call this function as the first thing in an instance initialization function.
Inserts an action group into the widget's actions.
Children of widget that implement Gtk.Actionable can
then be associated with actions in group by setting their
“action-name” to prefix.action-name.
Note that inheritance is defined for individual actions. I.e.
even if you insert a group with prefix prefix, actions with
the same prefix will still be inherited from the parent, unless
the group contains an action with the same name.
If group is NULL, a previously inserted group for name is
removed from widget.

Optionalgroup: Gio.ActionGroupan action group
Sets the parent widget of the widget.
In contrast to Gtk.Widget.set_parent, this function
inserts widget at a specific position into the list of children
of the parent widget.
It will be placed after previous_sibling, or at the beginning if
previous_sibling is NULL.
After calling this function, gtk_widget_get_prev_sibling (widget)
will return previous_sibling.
If parent is already set as the parent widget of widget, this
function can also be used to reorder widget in the child widget
list of parent.
This function is primarily meant for widget implementations; if you are just using a widget, you must use its own API for adding children.
Sets the parent widget of the widget.
In contrast to Gtk.Widget.set_parent, this function
inserts widget at a specific position into the list of children
of the parent widget.
It will be placed before next_sibling, or at the end if
next_sibling is NULL.
After calling this function, gtk_widget_get_next_sibling (widget)
will return next_sibling.
If parent is already set as the parent widget of widget, this function
can also be used to reorder widget in the child widget list of parent.
This function is primarily meant for widget implementations; if you are just using a widget, you must use its own API for adding children.
Inserts length bytes of text into the contents of the
widget, at position position.
Note that the position is in characters, not in bytes.
The function updates position to point after the newly
inserted text.

Determines whether the widget is a descendent of ancestor.
another Gtk.Widget
true if ancestor contains widget as a child, grandchild, great grandchild, etc
Determines whether the widget can be drawn to.
A widget can be drawn if it is mapped and visible.
true if widget is drawable
Checks whether object has a [floating][floating-ref] reference.
true if object has a floating reference
Determines if the widget is the focus widget within its toplevel.
This does not mean that the Gtk.Widget.has_focus property is necessarily set; Gtk.Widget.has_focus will only be set if the toplevel widget additionally has the global input focus.
true if the widget is the focus widget
Returns the widget’s effective sensitivity.
This means it is sensitive itself and also its parent widget is sensitive.
true if the widget is effectively sensitive
Determines whether the widget and all its parents are marked as visible.
This function does not check if the widget is obscured in any way.
See also Gtk.Widget.get_visible and Gtk.Widget.set_visible.
true if the widget and all its parents are visible
Emits the Gtk.Widget::keynav-failed signal on the widget.
This function should be called whenever keyboard navigation within a single widget hits a boundary.
The return value of this function should be interpreted in a way similar to the return value of Gtk.Widget.child_focus. When true is returned, stay in the widget, the failed keyboard navigation is ok and/or there is nowhere we can/should move the focus to. When false is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling Gtk.Widget.child_focus on the widget’s toplevel.
The default Gtk.Widget::keynav-failed handler returns
false for Gtk.DirectionType.TAB-FORWARD and
Gtk.DirectionType.TAB-BACKWARD. For the other values
of Gtk.DirectionType it returns true.
Whenever the default handler returns true, it also calls Gtk.Widget.error_bell to notify the user of the failed keyboard navigation.
A use case for providing an own implementation of ::keynav-failed
(either by connecting to it or by overriding it) would be a row of
Gtk.Entry widgets where the user should be able to navigate
the entire row with the cursor keys, as e.g. known from user
interfaces that require entering license keys.
direction of focus movement
true if stopping keyboard navigation is fine, false if the emitting widget should try to handle the keyboard navigation attempt in its parent widget
Returns the widgets for which this widget is the target of a mnemonic.
Typically, these widgets will be labels. See, for example, Gtk.Label.set_mnemonic_widget.
The widgets in the list are not individually referenced.
If you want to iterate through the list and perform actions
involving callbacks that might destroy the widgets, you
must call g_list_foreach (result, (GFunc)g_object_ref, NULL)
first, and then unref all the widgets afterwards.
the list of mnemonic labels
Causes a widget to be mapped if it isn’t already.
This function is only for use in widget implementations.
Measures widget in the orientation orientation and for the given for_size.
As an example, if orientation is Gtk.Orientation.HORIZONTAL and for_size
is 300, this functions will compute the minimum and natural width of widget
if it is allocated at a height of 300 pixels.
See GtkWidget’s geometry management section for a more details on implementing Gtk.Widget.measure.
the orientation to measure
Size for the opposite of orientation, i.e. if orientation is Gtk.Orientation.HORIZONTAL, this is the height the widget should be measured with. The Gtk.Orientation.VERTICAL case is analogous. This way, both height-for-width and width-for-height requests can be implemented. If no size is known, -1 can be passed.
Emits the Gtk.Widget::mnemonic-activate signal.
true if there are other widgets with the same mnemonic
true if the signal has been handled
Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than
g_object_notify().
One way to avoid using g_object_notify() from within the
class that registered the properties, and using g_object_notify_by_pspec()
instead, is to store the GParamSpec used with
g_object_class_install_property() inside a static array, e.g.:
typedef enum
{
PROP_FOO = 1,
PROP_LAST
} MyObjectProperty;
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", NULL, NULL,
0, 100,
50,
G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the GObject.ParamSpec of a property installed on the class of object.
Returns a list model to track the children of the widget.
Calling this function will enable extra internal bookkeeping to track children and emit signals on the returned listmodel. It may slow down operations a lot.
Applications should try hard to avoid calling this function because of the slowdowns.
a list model tracking widget's children
Returns a list model to track the event controllers of the widget.
Calling this function will enable extra internal bookkeeping to track controllers and emit signals on the returned listmodel. It may slow down operations a lot.
Applications should try hard to avoid calling this function because of the slowdowns.
a list model tracking widget's controllers
Finds the descendant of the widget closest to a point.
The point (x, y) must be given in widget coordinates, so (0, 0)
is assumed to be the top left of widget's content area.
Usually widgets will return NULL if the given coordinate is not
contained in widget checked via Gtk.Widget.contains.
Otherwise they will recursively try to find a child that does
not return NULL. Widgets are however free to customize their
picking algorithm.
This function is used on the toplevel to determine the widget below the mouse cursor for purposes of hover highlighting and delivering events.
the widget's descendant at (x, y)
Indicates that some progress is made, but you don’t know how much.
Causes the entry’s progress indicator to enter “activity
mode”, where a block bounces back and forth. Each call to
gtk_entry_progress_pulse() causes the block to move by a
little bit (the amount of movement per pulse is determined
by Gtk.Entry.set_progress_pulse_step).
Flags the widget for a rerun of the Gtk.Widget.size_allocate function.
Use this function instead of Gtk.Widget.queue_resize
when the widget's size request didn't change but it wants to
reposition its contents.
An example user of this function is Gtk.Widget.set_halign.
This function is only for use in widget implementations.
Schedules this widget to be redrawn.
The redraw will happen in the paint phase of the current or the next frame.
This means widget's Gtk.Widget.snapshot
implementation will be called.
Flags a widget to have its size renegotiated.
This should be called when a widget for some reason has a new size request. For example, when you change the text in a Gtk.Label, the label queues a resize to ensure there’s enough space for the new text.
Note that you cannot call gtk_widget_queue_resize() on a widget
from inside its implementation of the Gtk.Widget.size_allocate
virtual method. Calls to gtk_widget_queue_resize() from inside
Gtk.Widget.size_allocate will be silently ignored.
This function is only for use in widget implementations.
Creates the GDK resources associated with a widget.
Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically.
Realizing a widget requires all the widget’s parent widgets to be
realized; calling this function realizes the widget’s parents
in addition to widget itself. If a widget is not yet inside a
toplevel window when you realize it, bad things will happen.
This function is primarily used in widget implementations, and
isn’t very useful otherwise. Many times when you think you might
need it, a better approach is to connect to a signal that will be
called after the widget is realized automatically, such as
Gtk.Widget::realize.
Increases the reference count of object.
Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type
of object will be propagated to the return type (using the GCC typeof()
extension), so any casting the caller needs to do on the return type must be
explicit.
the same object
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
object
Removes an event controller from the widget.
The removed event controller will not receive any more events, and should not be used again.
Widgets will remove all event controllers automatically when they are destroyed, there is normally no need to call this function.
an event controller
Removes a style from the widget.
After this, the style of widget will stop matching for css_class.
style class to remove from widget, without the leading period
Removes a widget from the list of mnemonic labels for this widget.
See Gtk.Widget.list_mnemonic_labels.
The widget must have previously been added to the list with Gtk.Widget.add_mnemonic_label.
Removes a tick callback previously registered with Gtk.Widget.add_tick_callback.
an ID returned by Gtk.Widget.add_tick_callback
Emits the Gtk.CellEditable::remove-widget signal.
Reset the input method context of the entry if needed.
This can be necessary in the case where modifying the buffer would confuse on-going input method behavior.
Resets the accessible property to its default value.

Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Selects a region of text.
The characters that are selected are those characters at positions
from start_pos up to, but not including end_pos. If end_pos is
negative, then the characters selected are those characters from
start_pos to the end of the text.
Note that positions are specified in characters, not bytes.
start of region
end of region
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.
Object containing the properties to set
Sets the parent and sibling of an accessible object.
This function is meant to be used by accessible implementations that are not part of the widget hierarchy, and but act as a logical bridge between widgets. For instance, if a widget creates an object that holds metadata for each child, and you want that object to implement the Gtk.Accessible interface, you will use this function to ensure that the parent of each child widget is the metadata object, and the parent of each metadata object is the container widget.
Optionalparent: Gtk.Accessiblethe parent accessible object
Optionalnext_sibling: Gtk.Accessiblethe sibling accessible object
Sets whether pressing Enter in the entry will activate the default
widget for the window containing the entry.
This usually means that the dialog containing the entry will be closed, since the default widget is usually one of the dialog buttons.
true to activate window’s default widget on Enter keypress
Sets the alignment for the contents of the entry.
This controls the horizontal positioning of the contents when the displayed text is shorter than the width of the entry.
See also: Gtk.Editable.xalign
The horizontal alignment, from 0 (left) to 1 (right). Reversed for RTL layouts
Sets a Pango.AttrList.
The attributes in the list are applied to the entry text.
Since the attributes will be applied to text that changes as the user types, it makes most sense to use attributes with unlimited extent.
Set the Gtk.EntryBuffer object which holds the text for this widget.
Sets whether the input focus can enter the widget or any of its children.
Applications should set can_focus to false to mark a
widget as for pointer/touch use only.
Note that having can_focus be true is only one of the
necessary conditions for being focusable. A widget must
also be sensitive and focusable and not have an ancestor
that is marked as not can-focus in order to receive input
focus.
See Gtk.Widget.grab_focus for actually setting the input focus on a widget.
whether the input focus can enter the widget or any of its children
Sets whether the widget can be the target of pointer events.
whether this widget should be able to receive pointer events
Sets whether the widget should be mapped along with its parent.
The child visibility can be set for widget before it is added to a container with Gtk.Widget.set_parent, to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of true when the widget is removed from a container.
Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself.
This function is only useful for widget implementations and should never be called by an application.
whether widget should be mapped along with its parent
Sets completion to be the auxiliary completion object
to use with entry.
All further configuration of the completion mechanism is
done on completion using the Gtk.EntryCompletion API.
Completion is disabled if completion is set to null.
Optionalcompletion: Gtk.EntryCompletionReplaces the current style classes of the widget with classes.
NULL-terminated list of style classes
Sets the cursor to be shown when the pointer hovers over the widget.
This is a utility function that creates a cursor via
Gdk.Cursor.new_from_name and then sets it on widget
with Gtk.Widget.set_cursor. See those functions for
details.
On top of that, this function allows name to be NULL, which
will do the same as calling Gtk.Widget.set_cursor
with a NULL cursor.
Optionalname: stringthe name of the cursor
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a GLib.Quark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the GLib.Quark storage growing unbounded.
name of the key
Optionaldata: anydata to associate with that key
Sets the reading direction on the widget.
This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done.
Generally, applications will let the default reading direction prevail, except for widgets where the children are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification).
If the direction is set to Gtk.TextDirection.NONE, then the value set by Gtk.Widget.set_default_direction will be used.
the new direction
Determines if the user can edit the text in the editable widget.
true if the user is allowed to edit the text in the widget
If enabled, changes to editable will be saved for undo/redo
actions.
This results in an additional copy of text changes and are not
stored in secure memory. As such, undo is forcefully disabled
when Gtk.Text.visibility is set to false.
if undo/redo should be enabled
Set the focus child of the widget.
This function is only suitable for widget implementations. If you want a certain widget to get the input focus, call Gtk.Widget.grab_focus on it.
Sets whether the widget should grab focus when it is clicked with the mouse.
Making mouse clicks not grab focus is useful in places like toolbars where you don’t want the keyboard focus removed from the main area of the application.
whether the widget should grab focus when clicked with the mouse
Sets whether the widget can own the input focus.
Widget implementations should set focusable to true in
their init() function if they want to receive keyboard input.
Note that having focusable be true is only one of the
necessary conditions for being focusable. A widget must
also be sensitive and can-focus and not have an ancestor
that is marked as not can-focus in order to receive input
focus.
See Gtk.Widget.grab_focus for actually setting the input focus on a widget.
whether or not widget can own the input focus
Sets the font map to use for text rendering in the widget.
The font map is the object that is used to look up fonts. Setting a custom font map can be useful in special situations, e.g. when you need to add application-specific fonts to the set of available fonts.
When not set, the widget will inherit the font map from its parent.
Sets the cairo_font_options_t used for text rendering
in the widget.
When not set, the default font options for the Gdk.Display will be used.
Optionaloptions: default.FontOptionsa cairo_font_options_t struct to unset any previously set default font options
Sets whether the entry has a beveled frame around it.
new value
Sets the has-tooltip property on the widget.
whether or not widget has a tooltip
Sets whether the widget would like any available extra horizontal space.
When a user resizes a window, widgets with expand set to true generally receive the extra space. For example, a list or scrollable area or document in your window would often be set to expand.
Call this function to set the expand flag if you would like your widget to become larger horizontally when the window has extra room.
By default, widgets automatically expand if any of their children
want to expand. (To see if a widget will automatically expand given
its current children and state, call Gtk.Widget.compute_expand.
A widget can decide how the expandability of children affects its
own expansion by overriding the compute_expand virtual method on
Gtk.Widget.).
Setting hexpand explicitly with this function will override the automatic expand behavior.
This function forces the widget to expand or not to expand, regardless of children. The override occurs because Gtk.Widget.set_hexpand sets the hexpand-set property (see Gtk.Widget.set_hexpand_set) which causes the widget’s hexpand value to be used, rather than looking at children and widget state.
whether to expand
Sets whether the hexpand flag will be used.
The Gtk.Widget.hexpand_set property will be set automatically when you call Gtk.Widget.set_hexpand to set hexpand, so the most likely reason to use this function would be to unset an explicit expand flag.
If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.
value for hexpand-set property
Sets whether the icon is activatable.
Icon position
true if the icon should be activatable
Sets up the icon at the given position as drag source.
This makes it so that GTK will start a drag operation when the user clicks and drags the icon.
icon position

Sets the icon shown in the entry at the specified position from the current icon theme.
If the icon isn’t known, a “broken image” icon will be displayed instead.

Use null for tooltip to remove an existing tooltip.
See also Gtk.Widget.set_tooltip_text and Gtk.Entry.set_icon_tooltip_markup.
If you unset the widget tooltip via
Gtk.Widget.set_tooltip_text or
Gtk.Widget.set_tooltip_markup, this sets
Gtk.Widget.has_tooltip to false, which suppresses
icon tooltips too. You can resolve this by then calling
Gtk.Widget.set_has_tooltip to set
Gtk.Widget.has_tooltip back to true, or
setting at least one non-empty tooltip on any icon
achieves the same result.

Sets the character to use in place of the actual text in “password mode”.
See Gtk.Entry.set_visibility for how to enable “password mode”.
By default, GTK picks the best invisible char available in the current font. If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.

Sets the maximum allowed length of the contents of the widget.
If the current contents are longer than the given length, then they will be truncated to fit. The length is in characters.
This is equivalent to getting entry's Gtk.EntryBuffer and
calling Gtk.EntryBuffer.set_max_length on it.

Sets the desired maximum width in characters of editable.

Sets the text that will be used in the context menu of the Gtk.Entry when the specified icon is activatable. Selecting this item in the menu results, from all aspects, the same than clicking on the specified icon. This greatly simplifies making accessible applications, because the icons aren't focusable when using keyboard navigation. This is why Gtk recommends to add the same action to the context menu.
either GTK_ENTRY_ICON_PRIMARY or GTK_ENTRY_ICON_SECONDARY
the text used for the menu item in the context menu, or NULL to not add a menu item.
Sets a widgets name.
Setting a name allows you to refer to the widget from a CSS file. You can apply a style to widgets with a particular name in the CSS file. See the documentation for the CSS syntax (on the same page as the docs for Gtk.StyleContext.
Note that the CSS syntax has certain special characters to delimit and represent elements in a selector (period, #, >, *...), so using these will make your widget impossible to match by name. Any combination of alphanumeric symbols, dashes and underscores will suffice.
name for the widget
Requests the widget to be rendered partially transparent.
An opacity of 0 is fully transparent and an opacity of 1 is fully opaque.
Opacity works on both toplevel widgets and child widgets, although there are some limitations: For toplevel widgets, applying opacity depends on the capabilities of the windowing system. On X11, this has any effect only on X displays with a compositing manager, see Gdk.Display.is_composited. On Windows and Wayland it will always work, although setting a window’s opacity after the window has been shown may cause some flicker.
Note that the opacity is inherited through inclusion — if you set a toplevel to be partially translucent, all of its content will appear translucent, since it is ultimatively rendered on that toplevel. The opacity value itself is not inherited by child widgets (since that would make widgets deeper in the hierarchy progressively more translucent). As a consequence, Gtk.Popover instances and other Gtk.Native widgets with their own surface will use their own opacity value, and thus by default appear non-translucent, even if they are attached to a toplevel that is translucent.
desired opacity, between 0 and 1
Sets how the widget treats content that is drawn outside the it's content area.
See the definition of Gtk.Overflow for details.
This setting is provided for widget implementations and should not be used by application code.
The default value is Gtk.Overflow.VISIBLE.
Sets whether the text is overwritten when typing in the Gtk.Entry.
new value
Sets the parent widget of the widget.
This takes care of details such as updating the state and style of the child to reflect its new location and resizing the parent. The opposite function is Gtk.Widget.unparent.
This function is useful only when implementing subclasses of Gtk.Widget.
Sets text to be displayed in entry when it is empty.
This can be used to give a visual hint of the expected contents of the Gtk.Entry.
Optionaltext: stringa string to be displayed when entry is empty and unfocused
Sets the cursor position in the editable to the given value.
The cursor is displayed before the character with the given (base 0)
index in the contents of the editable. The value must be less than
or equal to the number of characters in the editable. A value of -1
indicates that the position should be set after the last character
of the editable. Note that position is in characters, not in bytes.

Causes the entry’s progress indicator to “fill in” the given fraction of the bar.
The fraction should be between 0.0 and 1.0, inclusive.

Sets whether the widget will be treated as the default widget within its toplevel when it has the focus, even if another widget is the default.
whether or not widget can be a default widget
Sets the sensitivity of the widget.
A widget is sensitive if the user can interact with it. Insensitive widgets are “grayed out” and the user can’t interact with them. Insensitive widgets are known as “inactive”, “disabled”, or “ghosted” in some other toolkits.
true to make the widget sensitive
Sets the minimum size of the widget.
That is, the widget’s size request will be at least width
by height. You can use this function to force a widget to
be larger than it normally would be.
In most cases, Gtk.Window.set_default_size is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request.
Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it is basically impossible to hardcode a size that will always work.
The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested.
If the size request in a given direction is -1 (unset), then the “natural” size request of the widget will be used instead.
The size request set here does not include any margin from the properties Gtk.Widget.margin_start, Gtk.Widget.margin_end, Gtk.Widget.margin_top, and Gtk.Widget.margin_bottom, but it does include pretty much all other padding or border properties set by any subclass of Gtk.Widget.
width widget should request, or -1 to unset

Turns on flag values in the current widget state.
Typical widget states are insensitive, prelighted, etc.
This function accepts the values Gtk.StateFlags.DIR-LTR and Gtk.StateFlags.DIR-RTL but ignores them. If you want to set the widget's direction, use Gtk.Widget.set_direction.
This function is for use in widget implementations.

value for vexpand-set property
Sets whether the contents of the entry are visible or not.
When visibility is set to false, characters are displayed
as the invisible char, and will also appear that way when
the text in the entry widget is copied elsewhere.
By default, GTK picks the best invisible character available in the current font, but it can be changed with Gtk.Entry.set_invisible_char.
Note that you probably want to set Gtk.Entry.input_purpose
to Gtk.InputPurpose.PASSWORD or Gtk.InputPurpose.PIN to
inform input methods about the purpose of this entry,
in addition to setting visibility to false.
true if the contents of the entry are displayed as plaintext
Sets the visibility state of widget.
Note that setting this to true doesn’t mean the widget is actually viewable, see Gtk.Widget.get_visible.

Changes the size request of the editable to be about the
right size for n_chars characters.
Note that it changes the size request, the size can still
be affected by how you pack the widget into containers.
If n_chars is -1, the size reverts to the default size.
width in chars
Returns whether the widget should contribute to the measuring and allocation of its parent.
This is false for invisible children, but also for children that have their own surface, such as Gtk.Popover instances.
true if child should be included in measuring and allocating
Flags a widget to be displayed.
Any widget that isn’t shown will not appear on the screen.
Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen.
When a toplevel widget is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel widget is realized and mapped.
Allocates widget with a transformation that translates
the origin to the position in allocation.
This is a simple form of Gtk.Widget.allocate.
Snapshots a child of the widget.
When a widget receives a call to the snapshot function,
it must send synthetic Gtk.Widget.snapshot calls
to all children. This function provides a convenient way
of doing this. A widget, when it receives a call to its
Gtk.Widget.snapshot function, calls
gtk_widget_snapshot_child() once for each child, passing in
the snapshot the widget received.
This function takes care of translating the origin of snapshot,
and deciding whether the child needs to be snapshot.
It does nothing for children that implement Gtk.Native.

Begins editing on a cell_editable.
The Gtk.CellRenderer for the cell creates and returns a Gtk.CellEditable from
gtk_cell_renderer_start_editing(), configured for the Gtk.CellRenderer type.
gtk_cell_editable_start_editing() can then set up cell_editable suitably for
editing a cell, e.g. making the Esc key emit Gtk.CellEditable::editing-done.
Note that the cell_editable is created on-demand for the current edit; its
lifetime is temporary and does not persist across other edits and/or cells.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
name of the key
the data if found, or null if no such data exists.
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of
g_object_steal_qdata() would have left the destroy function set,
and thus the partial string list would have been freed upon
g_object_set_qdata_full().

Stops a signal's emission by the given signal name. This will prevent the default handler and any subsequent signal handlers from being invoked.
Name of the signal to stop emission of
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one GObject.Object::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Translates coordinates relative to src_widget’s allocation
to coordinates relative to dest_widget’s allocations.
In order to perform this operation, both widget must share
a common ancestor. If that is not the case, dest_x and dest_y
are set to 0 and false is returned.

Causes a widget to be unmapped if it’s currently mapped.
This function is only for use in widget implementations.
Removes widget from its parent.
This function is only for use in widget implementations, typically in dispose.
Causes a widget to be unrealized.
This frees all GDK resources associated with the widget.
This function is only useful in widget implementations.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the GObject.Object may be reused in future (for example, if it is
an instance variable of another object), it is recommended to clear the
pointer to null rather than retain a dangling pointer to a potentially
invalid GObject.Object instance. Use g_clear_object() for this.
Unsets the invisible char, so that the default invisible char is used again. See Gtk.Entry.set_invisible_char.
Turns off flag values for the current widget state.

Virtualvfunc_Class handler for the Gtk.Entry::activate signal. The default
implementation activates the gtk.activate-default action.
Virtualvfunc_Virtualvfunc_Virtualvfunc_Computes whether a container should give this widget extra space when possible.
Virtualvfunc_the constructed function is called by g_object_new() as the
final step of the object creation process. At the point of the call, all
construction properties have been set on the object. The purpose of this
call is to allow for object initialisation steps that can only be performed
after construction properties have been set. constructed implementors
should chain up to the constructed call of their parent class to allow it
to complete its initialisation.
Virtualvfunc_Tests if a given point is contained in the widget.
The coordinates for (x, y) must be in widget coordinates, so
(0, 0) is assumed to be the top left of widget's content area.
X coordinate to test, relative to widget's origin
Y coordinate to test, relative to widget's origin
Virtualvfunc_Vfunc called when the CSS used by widget was changed. Widgets should then discard their caches that depend on CSS and queue resizes or redraws accordingly. The default implementation will take care of this for all the default CSS properties, so implementations must chain up.

Virtualvfunc_Deletes a sequence of characters.
The characters that are deleted are those characters at positions
from start_pos up to, but not including end_pos. If end_pos is
negative, then the characters deleted are those from start_pos to
the end of the text.
Note that the positions are specified in characters, not bytes.

Virtualvfunc_Signal emitted when the text direction of a widget changes.
Virtualvfunc_Virtualvfunc_the dispose function is supposed to drop all references to other
objects, but keep the instance otherwise intact, so that client method
invocations still work. It may be run multiple times (due to reference
loops). Before returning, dispose should chain up to the dispose method
of the parent class.
Virtualvfunc_Deletes a sequence of characters.
The characters that are deleted are those characters at positions

Virtualvfunc_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the

Virtualvfunc_Virtualvfunc_Retrieves the accessible parent for an accessible object.
This function returns NULL for top level widgets.
Virtualvfunc_Virtualvfunc_Queries the coordinates and dimensions of this accessible
This functionality can be overridden by Gtk.Accessible implementations, e.g. to get the bounds from an ignored child widget.
Virtualvfunc_Gets the Gtk.Editable that editable is delegating its
implementation to.
Typically, the delegate is a Gtk.Text widget.
Virtualvfunc_Retrieves the first accessible child of an accessible object.
Virtualvfunc_The getter corresponding to set_id. Implement this
if you implement set_id.
Virtualvfunc_Virtualvfunc_Retrieves the next accessible sibling of an accessible object
Virtualvfunc_Queries a platform state, such as focus.
This functionality can be overridden by Gtk.Accessible implementations, e.g. to get platform state from an ignored child widget, as is the case for Gtk.Text wrappers.
platform state to query
Virtualvfunc_Virtualvfunc_Gets whether the widget prefers a height-for-width layout or a width-for-height layout.
Single-child widgets generally propagate the preference of their child, more complex widgets need to request something either in context of their children or in context of their allocation capabilities.
Virtualvfunc_Retrieves the selection bound of the editable.
start_pos will be filled with the start of the selection and
end_pos with end. If no text was selected both will be identical
and false will be returned.
Note that positions are specified in characters, not bytes.
Virtualvfunc_Retrieves the contents of editable.
The returned string is owned by GTK and must not be modified or freed.
Virtualvfunc_Causes widget to have the keyboard focus for the window
that it belongs to.
If widget is not focusable, or its Gtk.Widget.grab_focus
implementation cannot transfer the focus to a descendant of widget
that is focusable, it will not take focus and false will be returned.
Calling Gtk.Widget.grab_focus on an already focused widget is allowed, should not have an effect, and return true.
Virtualvfunc_Reverses the effects of [method.Gtk.Widget.show].
This is causing the widget to be hidden (invisible to the user).
Virtualvfunc_Inserts length bytes of text into the contents of the
widget, at position position.

The function updates position to point after the newly
inserted text.

location of the position text will be inserted at
Virtualvfunc_Emits the Gtk.Widget::keynav-failed signal on the widget.
This function should be called whenever keyboard navigation within a single widget hits a boundary.
The return value of this function should be interpreted in a way similar to the return value of Gtk.Widget.child_focus. When true is returned, stay in the widget, the failed keyboard navigation is ok and/or there is nowhere we can/should move the focus to. When false is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling Gtk.Widget.child_focus on the widget’s toplevel.
The default Gtk.Widget::keynav-failed handler returns
false for Gtk.DirectionType.TAB-FORWARD and
Gtk.DirectionType.TAB-BACKWARD. For the other values
of Gtk.DirectionType it returns true.
Whenever the default handler returns true, it also calls Gtk.Widget.error_bell to notify the user of the failed keyboard navigation.
A use case for providing an own implementation of ::keynav-failed
(either by connecting to it or by overriding it) would be a row of
Gtk.Entry widgets where the user should be able to navigate
the entire row with the cursor keys, as e.g. known from user
interfaces that require entering license keys.
direction of focus movement
Virtualvfunc_Causes a widget to be mapped if it isn’t already.
This function is only for use in widget implementations.
Virtualvfunc_Measures widget in the orientation orientation and for the given for_size.
As an example, if orientation is Gtk.Orientation.HORIZONTAL and for_size
is 300, this functions will compute the minimum and natural width of widget
if it is allocated at a height of 300 pixels.
See GtkWidget’s geometry management section for a more details on implementing Gtk.Widget.measure.
the orientation to measure
Size for the opposite of orientation, i.e. if orientation is Gtk.Orientation.HORIZONTAL, this is the height the widget should be measured with. The Gtk.Orientation.VERTICAL case is analogous. This way, both height-for-width and width-for-height requests can be implemented. If no size is known, -1 can be passed.
Virtualvfunc_Emits the Gtk.Widget::mnemonic-activate signal.
true if there are other widgets with the same mnemonic
Virtualvfunc_Signal emitted when a change of focus is requested
Virtualvfunc_Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class
that registered the property, you should use g_object_notify_by_pspec()
instead.
Note that emission of the notify signal may be blocked with
g_object_freeze_notify(). In this case, the signal emissions are queued
and will be emitted (in reverse order) when g_object_thaw_notify() is
called.
Virtualvfunc_Called when a builder finishes the parsing of a UI definition. It is normally not necessary to implement this, unless you need to perform special cleanup actions. Gtk.Window sets the Gtk.Widget.visible property here.
Virtualvfunc_Virtualvfunc_Creates the GDK resources associated with a widget.
Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically.
Realizing a widget requires all the widget’s parent widgets to be
realized; calling this function realizes the widget’s parents
in addition to widget itself. If a widget is not yet inside a
toplevel window when you realize it, bad things will happen.
This function is primarily used in widget implementations, and
isn’t very useful otherwise. Many times when you think you might
need it, a better approach is to connect to a signal that will be
called after the widget is realized automatically, such as
Gtk.Widget::realize.
Virtualvfunc_Emits the Gtk.CellEditable::remove-widget signal.
Virtualvfunc_Called when the widget gets added to a Gtk.Root widget. Must chain up
Virtualvfunc_Sets a property of a buildable object.
It is normally not necessary to implement this, g_object_set_property()
is used by default. Gtk.Window implements this to delay showing itself
(i.e. setting the Gtk.Widget.visible property) until the whole
interface is created.
Virtualvfunc_Set the focus child of the widget.
This function is only suitable for widget implementations. If you want a certain widget to get the input focus, call Gtk.Widget.grab_focus on it.
Virtualvfunc_Stores the id attribute given in the Gtk.Builder UI definition. Gtk.Widget stores the name as object data. Implement this method if your object has some notion of “ID” and it makes sense to map the XML id attribute to it.
Virtualvfunc_the generic setter for all properties of this type. Should be
overridden for every type with properties. If implementations of
set_property don't emit property change notification explicitly, this will
be done implicitly by the type system. However, if the notify signal is
emitted explicitly, the type system will not emit it a second time.
Virtualvfunc_Selects a region of text.
The characters that are selected are those characters at positions
from start_pos up to, but not including end_pos. If end_pos is
negative, then the characters selected are those characters from
start_pos to the end of the text.
Note that positions are specified in characters, not bytes.
start of region
end of region
Virtualvfunc_Flags a widget to be displayed.
Any widget that isn’t shown will not appear on the screen.
Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen.
When a toplevel widget is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel widget is realized and mapped.
Virtualvfunc_Called to set the allocation, if the widget does not have a layout manager.
Virtualvfunc_Virtualvfunc_Begins editing on a cell_editable.
The Gtk.CellRenderer for the cell creates and returns a Gtk.CellEditable from
gtk_cell_renderer_start_editing(), configured for the Gtk.CellRenderer type.
gtk_cell_editable_start_editing() can then set up cell_editable suitably for
editing a cell, e.g. making the Esc key emit Gtk.CellEditable::editing-done.
Note that the cell_editable is created on-demand for the current edit; its
lifetime is temporary and does not persist across other edits and/or cells.
Virtualvfunc_Signal emitted when the widget state changes,
see gtk_widget_get_state_flags().
Virtualvfunc_Emitted when a system setting was changed. Must chain up.
Virtualvfunc_Causes a widget to be unmapped if it’s currently mapped.
This function is only for use in widget implementations.
Virtualvfunc_Causes a widget to be unrealized.
This frees all GDK resources associated with the widget.
This function is only useful in widget implementations.
Virtualvfunc_Called when the widget is about to be removed from its Gtk.Root widget. Must chain up
This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

Staticinterface_Add a property to an interface; this is only useful for interfaces

g_object_class_override_property() will be used so that the object

A single-line text entry widget.
A fairly large set of key bindings are supported by default. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.
When using an entry for passwords and other sensitive information, it can be put into “password mode” using Gtk.Entry.set_visibility. In this mode, entered text is displayed using a “invisible” character. By default, GTK picks the best invisible character that is available in the current font, but it can be changed with Gtk.Entry.set_invisible_char.
Gtk.Entry has the ability to display progress or activity information behind the text. To make an entry display such information, use Gtk.Entry.set_progress_fraction or Gtk.Entry.set_progress_pulse_step.
Additionally, Gtk.Entry can show icons at either side of the entry. These icons can be activatable by clicking, can be set up as drag source and can have tooltips. To add an icon, use Gtk.Entry.set_icon_from_gicon or one of the various other functions that set an icon from an icon name or a paintable. To trigger an action when the user clicks an icon, connect to the
Gtk.Entry::icon-presssignal. To allow DND operations from an icon, use Gtk.Entry.set_icon_drag_source. To set a tooltip on an icon, use Gtk.Entry.set_icon_tooltip_text or the corresponding function for markup.Note that functionality or information that is only available by clicking on an icon in an entry may not be accessible at all to users which are not able to use a mouse or other pointing device. It is therefore recommended that any such functionality should also be available by other means, e.g. via the context menu of the entry.
CSS nodes
Gtk.Entry has a main node with the name entry. Depending on the properties of the entry, the style classes .read-only and .flat may appear. The style classes .warning and .error may also be used with entries.
When the entry shows icons, it adds subnodes with the name image and the style class .left or .right, depending on where the icon appears.
When the entry shows progress, it adds a subnode with the name progress. The node has the style class .pulse when the shown progress is pulsing.
For all the subnodes added to the text node in various situations, see Gtk.Text.
GtkEntry as GtkBuildable
The Gtk.Entry implementation of the Gtk.Buildable interface supports a custom
<attributes>element, which supports any number of<attribute>elements. The<attribute>element has attributes named “name“, “value“, “start“ and “end“ and allows you to specify Pango.Attribute values for this label.An example of a UI definition fragment specifying Pango attributes:
The start and end attributes specify the range of characters to which the Pango attribute applies. If start and end are not specified, the attribute is applied to the whole text. Note that specifying ranges does not make much sense with translatable attributes. Use markup embedded in the translatable content instead.
Accessibility
Gtk.Entry uses the Gtk.AccessibleRole.TEXT_BOX role.
