Optionalproperties: Partial<Atk.NoOpObject.ConstructorProps>Internal$signalsCompile-time signal type information.
This instance property is generated only for TypeScript type checking. It is not defined at runtime and should not be accessed in JS code.
Static$gtypeAdds the specified column to the selection.
a gint representing a column in table
a gboolean representing if the column was successfully added to the selection, or 0 if value does not implement this interface.
Adds a relationship of the specified type with the specified target.
The Atk.RelationType of the relation
The Atk.Object which is to be the target of the relation.
TRUE if the relationship is added.
Adds the specified row to the selection.
a gint representing a row in table
a gboolean representing if row was successfully added to selection, or 0 if value does not implement this interface.
Adds the specified accessible child of the object to the object's selection.
a gint specifying the child index.
TRUE if success, FALSE otherwise.
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 property on source to bind
the target GObject.Object
the property on target to bind
flags to pass to GObject.Binding
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.

Perform the specified action on the object.
the action index corresponding to the action to be performed

SignalemitThis 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.
Gets the accessible id of the accessible.

Gets the keybinding which can be used to activate this action, if one exists. The string returned should contain localized, human-readable, key sequences as they would appear when displayed on screen. It must be in the format "mnemonic;sequence;shortcut".
Example: For a traditional "New..." menu item, the expected return value would be: "N;Alt+F:N;Ctrl+N" for the English locale and "N;Alt+D:N;Strg+N" for the German locale. If, hypothetically, this menu item lacked a mnemonic, it would be represented by ";;Ctrl+N" and ";;Strg+N" respectively.

The number of selected regions, or -1 in the case of failure.
Returns a non-localized string naming the specified action of the object. This name is generally not descriptive of the end result of the action, but instead names the 'interaction type' which the object supports. By convention, the above strings should be used to represent the actions which correspond to the common point-and-click interaction techniques of the same name: i.e. "click", "press", "release", "drag", "drop", "popup", etc. The "popup" action should be used to pop up a context menu for the object, if one exists.

the one assigned with atk_object_set_parent(), but it is assumed
that ATK implementors have ways to get the parent of the object
without the need of assigning it manually with
atk_object_set_parent(), and will return it with this method.
If you are only interested on the parent assigned with
atk_object_set_parent(), use atk_object_peek_parent().
an Atk.Object representing the accessible parent of the accessible
Gets the position of component in the form of
a point specifying component's top-left corner.
If the position can not be obtained (e.g. a non-embedded plug or missing support), x and y are set to -1.
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.

Returns the number of rows occupied by this cell accessible.
a gint representing the number of rows occupied by this cell, or 0 if the cell does not implement this method.
Creates an Atk.AttributeSet which consists of the attributes explicitly
set at the position offset in the text. start_offset and end_offset are
set to the start and end of the range around offset where the attributes are

after the range. See the enum AtkTextAttribute for types of text
attributes that can be returned. Note that other attributes may also be
returned.

a newly allocated string containing the selected text. Use g_free() to free the returned string.
Gets the number of accessible children currently selected.

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.
Emits a state-change signal for the specified state.
Note that as a general rule when the state of an existing object changes, emitting a notification is expected.

Gets the accessible parent of the accessible, if it has been
manually assigned with atk_object_set_parent. Otherwise, this
function returns null.
This method is intended as an utility for ATK implementors, and not
to be exposed to accessible tools. See atk_object_get_parent() for
further reference.
an Atk.Object representing the accessible parent of the accessible if assigned
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.

Gets the Atk.RelationSet associated with the object.
an Atk.RelationSet representing the relation set of the object.
Gets a reference to the accessible object representing the specified
selected child of the object.
Note: callers should not rely on null or on a zero value for
indication of whether AtkSelectionIface is implemented, they should
use type checking/interface checking macros or the
atk_get_accessible_value() convenience method.
a gint specifying the index in the selection set. (e.g. the ith selection as opposed to the ith child).
an Atk.Object representing the selected accessible, or null if selection does not implement this interface.
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().

Causes every child of the object to be selected if the object supports multiple selections.
TRUE if success, FALSE otherwise.
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 accessible ID of the accessible. This is not meant to be presented to the user, but to be an ID which is stable over application development. Typically, this is the gtkbuilder ID. Such an ID will be available for instance to identify a given well-known accessible object for tailored screen reading, or for automatic regression testing.

Sets the value for the given attribute_name inside document.
a character string representing the name of the attribute whose value is being set.

Sets the caption for the table.
a Atk.Object representing the caption to set for table
Sets the caret (cursor) position to the specified offset.
In the case of rich-text content, this method should either grab focus or move the sequential focus navigation starting point (if the application supports this concept) as if the user had clicked on the new caret position. Typically, this means that the target of this operation is the node containing the new caret position or one of its ancestors. In other words, after this method is called, if the user advances focus, it should move to the first focusable node following the new caret position.
Calling this method should also scroll the application viewport in a way that matches the behavior of the application's typical caret motion or tab navigation as closely as possible. This also means that if the application's caret motion or focus navigation does not trigger a scroll operation, this method should not trigger one either. If the application does not have a caret motion or focus navigation operation, this method should try to scroll the new caret position into view while minimizing unnecessary scroll motion.
the character offset of the new caret position
true if successful, false otherwise.
Sets the description text for the specified column of the table.
a gint representing a column in table
a gchar representing the description text to set for the specified column of the table
Sets the value of this object.
a GObject.Value which is the desired new accessible value.
true if new value is successfully set, false otherwise.
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.

Makes 1 or more selections within this document denoted by the given array of AtkTextSelections. Any existing physical selection (inside or outside this document) is replaced by the new selections. All objects within the given selection ranges must be descendants of this document. Otherwise FALSE will be returned.
a GArray of AtkTextSelections to be selected.
TRUE if the selection was made successfully; FALSE otherwise.
Sets the value of this object.
This method is intended to provide a way to change the value of the object. In any case, it is possible that the value can't be modified (ie: a read-only component). If the value changes due this call, it is possible that the text could change, and will trigger an Atk.Value.SignalSignatures.value_changed | Atk.Value::value-changed signal emission.
Note for implementors: the deprecated atk_value_set_current_value()
method returned TRUE or FALSE depending if the value was assigned
or not. In the practice several implementors were not able to
decide it, and returned TRUE in any case. For that reason it is not
required anymore to return if the value was properly assigned or
not.
a double which is the desired new accessible value.
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.

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.
Unblocks a handler so it will be called again during any signal emissions
Handler ID of the handler to be unblocked
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.

Virtualvfunc_Virtualvfunc_Virtualvfunc_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_Checks whether the specified point is within the extent of the component.

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_instance finalization function, should finish the finalization of
the instance begun in dispose and chain up to the finalize method of the
parent class.
Virtualvfunc_The signal handler which is executed when there is a focus event for an object. This virtual function is deprecated since 2.9.4 and it should not be overriden. Use the Atk.Object.SignalSignatures.state_change | Atk.Object::state-change "focused" signal instead.

component, on a scale from 0 (fully transparent) to 1.0
(fully opaque).
Virtualvfunc_Get a list of properties applied to this object as a whole, as an Atk.AttributeSet consisting of name-value pairs. As such these attributes may be considered weakly-typed properties or annotations, as distinct from strongly-typed object data available via other get/set methods. Not all objects have explicit "name-value pair" Atk.AttributeSet properties.

values cannot be obtained (for instance, if the object is not onscreen).
If the size can not be obtained (e.g. missing support), x and y are set to -1.
Virtualvfunc_Gets the minimum increment by which the value of this object may be changed. If zero, the minimum increment is undefined, which may mean that it is limited only by the floating point precision of the platform.
Virtualvfunc_Gets a gint representing the index at the specified row and
column.

a gint representing a column in table
Virtualvfunc_Gets the 0-based index of this accessible in its parent; returns -1 if the accessible does not have an accessible parent.
Virtualvfunc_Gets the keybinding which can be used to activate this action, if one exists. The string returned should contain localized, human-readable, key sequences as they would appear when displayed on screen. It must be in the format "mnemonic;sequence;shortcut".
Example: For a traditional "New..." menu item, the expected return value would be: "N;Alt+F:N;Ctrl+N" for the English locale and "N;Alt+D:N;Strg+N" for the German locale. If, hypothetically, this menu item lacked a mnemonic, it would be represented by ";;Ctrl+N" and ";;Strg+N" respectively.

Virtualvfunc_Gets the number of links within this hypertext document.
Virtualvfunc_Gets the number of rows in the table.
Virtualvfunc_Gets the number of selected regions.
Virtualvfunc_Returns a non-localized string naming the specified action of the object. This name is generally not descriptive of the end result of the action, but instead names the 'interaction type' which the object supports. By convention, the above strings should be used to represent the actions which correspond to the common point-and-click interaction techniques of the same name: i.e. "click", "press", "release", "drag", "drop", "popup", etc. The "popup" action should be used to pop up a context menu for the object, if one exists.
For technical reasons, some toolkits cannot guarantee that the
reported action is actually 'bound' to a nontrivial user event;
i.e. the result of some actions via atk_action_do_action() may be
NIL.
the action index corresponding to the action to be performed
Virtualvfunc_Gets a UTF-8 string indicating the POSIX-style LC_MESSAGES locale

the one assigned with atk_object_set_parent(), but it is assumed
that ATK implementors have ways to get the parent of the object
without the need of assigning it manually with
atk_object_set_parent(), and will return it with this method.
If you are only interested on the parent assigned with
atk_object_set_parent(), use atk_object_peek_parent().
Virtualvfunc_Gets the position of component in the form of
a point specifying component's top-left corner.
If the position can not be obtained (e.g. a non-embedded plug or missing support), x and y are set to -1.

Specify whether coordinates are relative to the screen or widget window.
Virtualvfunc_Virtualvfunc_Gets a gint representing the row at the specified index_.
a gint representing an index in table
Virtualvfunc_Gets the row and column indexes and span of this cell accessible.

Virtualvfunc_Creates an Atk.AttributeSet which consists of the attributes explicitly
set at the position offset in the text. start_offset and end_offset are
set to the start and end of the range around offset where the attributes are
invariant. Note that end_offset is the offset of the first character
after the range. See the enum AtkTextAttribute for types of text
attributes that can be returned. Note that other attributes may also be
returned.

a gint** that is to contain the selected row numbers
Virtualvfunc_Gets the text from the specified selection.
The selection number. The selected regions are assigned numbers that correspond to how far the region is from the start of the text. The selected region closest to the beginning of the text region is assigned the number 0, etc. Note that adding, moving or deleting a selected region can change the numbering.
Virtualvfunc_Gets the number of accessible children currently selected.
Note: callers should not rely on null or on a zero value for
indication of whether AtkSelectionIface is implemented, they should
use type checking/interface checking macros or the
atk_get_accessible_value() convenience method.
Virtualvfunc_Gets the size of the component in terms of width and height.
If the size can not be obtained (e.g. a non-embedded plug or missing support), width and height are set to -1.

offset is returned.
If granularity is ATK_TEXT_GRANULARITY_WORD the returned string
is from the word start at or before the offset to the word start after
the offset.
The returned string will contain the word at the offset if the offset is inside a word and will contain the word before the offset if the offset is not inside a word.
If granularity is ATK_TEXT_GRANULARITY_SENTENCE the returned string
is from the sentence start at or before the offset to the sentence
start after the offset.

Virtualvfunc_Virtualvfunc_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_Virtualvfunc_Sets the caption for the table.
a Atk.Object representing the caption to set for table
Virtualvfunc_Sets the caret (cursor) position to the specified offset.
In the case of rich-text content, this method should either grab focus or move the sequential focus navigation starting point (if the application supports this concept) as if the user had clicked on the new caret position. Typically, this means that the target of this operation is the node containing the new caret position or one of its ancestors. In other words, after this method is called, if the user advances focus, it should move to the first focusable node following the new caret position.
Calling this method should also scroll the application viewport in a way that matches the behavior of the application's typical caret motion or tab navigation as closely as possible. This also means that if the application's caret motion or focus navigation does not trigger a scroll operation, this method should not trigger one either. If the application does not have a caret motion or focus navigation operation, this method should try to scroll the new caret position into view while minimizing unnecessary scroll motion.

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_Virtualvfunc_Sets the description text for the specified row of table.
a gint representing a row in table
a gchar representing the description text to set for the specified row of table
Virtualvfunc_Virtualvfunc_Sets the attributes for a specified range. See the ATK_ATTRIBUTE macros (such as #ATK_ATTRIBUTE_LEFT_MARGIN) for examples of attributes that can be set. Note that other attributes that do not have corresponding ATK_ATTRIBUTE macros may also be set for certain text widgets.
start of range in which to set attributes
end of range in which to set attributes
Virtualvfunc_Changes the start and end offset of the specified selection.
The selection number. The selected regions are assigned numbers that correspond to how far the region is from the start of the text. The selected region closest to the beginning of the text region is assigned the number 0, etc. Note that adding, moving or deleting a selected region can change the numbering.
the new starting character offset of the selection
the new end position of (e.g. offset immediately past) the selection
Virtualvfunc_Set the size of the component in terms of width and height.
width to set for component
height to set for component
Virtualvfunc_Sets the summary description of the table.
an Atk.Object representing the summary description to set for table
Virtualvfunc_Set text contents of text.
string to set for text contents of text
Virtualvfunc_Makes 1 or more selections within this document denoted by the given array of AtkTextSelections. Any existing physical selection (inside or outside this document) is replaced by the new selections. All objects within the given selection ranges must be descendants of this document. Otherwise FALSE will be returned.
a GArray of AtkTextSelections to be selected.
Virtualvfunc_Sets the value of this object.
This method is intended to provide a way to change the value of the object. In any case, it is possible that the value can't be modified (ie: a read-only component). If the value changes due this call, it is possible that the text could change, and will trigger an Atk.Value.SignalSignatures.value_changed | Atk.Value::value-changed signal emission.
Note for implementors: the deprecated atk_value_set_current_value()
method returned TRUE or FALSE depending if the value was assigned
or not. In the practice several implementors were not able to
decide it, and returned TRUE in any case. For that reason it is not
required anymore to return if the value was properly assigned or
not.
a double which is the desired new accessible value.
Virtualvfunc_Virtualvfunc_Virtualvfunc_Virtualvfunc_the signal handler which is executed when there is a text change. This virtual function is deprecated sice 2.9.4 and it should not be overriden.
Virtualvfunc_Virtualvfunc_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.
GObject.Closure to watch
StaticnewStatic_Staticcompat_Optionaldata: anyStaticfind_Staticinstall_Staticinstall_the id for the new property
the GObject.ParamSpec for the new property
Staticinterface_Find the GObject.ParamSpec with the given name for an
interface. Generally, the interface vtable passed in as g_iface
will be the default vtable from g_type_default_interface_ref(), or,
if you know the interface has already been loaded,
g_type_default_interface_peek().
any interface vtable for the interface, or the default vtable for the interface
name of a property to look up.
Staticinterface_Add a property to an interface; this is only useful for interfaces
that are added to GObject-derived types. Adding a property to an
interface forces all objects classes with that interface to have a
compatible property. The compatible property could be a newly
created GObject.ParamSpec, but normally
g_object_class_override_property() will be used so that the object
class only needs to provide an implementation and inherits the
property description, default value, bounds, and so forth from the
interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
GObject.TypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
If pspec is a floating reference, it will be consumed.
any interface vtable for the interface, or the default vtable for the interface.
the GObject.ParamSpec for the new property
Staticinterface_Lists the properties of an interface.Generally, the interface
vtable passed in as g_iface will be the default vtable from
g_type_default_interface_ref(), or, if you know the interface has
already been loaded, g_type_default_interface_peek().
any interface vtable for the interface, or the default vtable for the interface
Staticlist_StaticnewvStaticoverride_the new property ID
the name of a property registered in a parent class or in an interface of this class.
An AtkObject which purports to implement all ATK interfaces.
An AtkNoOpObject is an AtkObject which purports to implement all ATK interfaces. It is the type of AtkObject which is created if an accessible object is requested for an object type for which no factory type is specified.
