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.

Creates a binding between source_property on source and target_property

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

Handler ID of the handler to be disconnected
SignalemitSets the current keyboard focus to be at cell, if the column contains
2 or more editable and activatable cells.
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.
Returns the current x alignment of tree_column. This value can range
between 0.0 and 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

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.
Adds the cell to end of the column. If expand is false, then the cell
is allocated no more space than it needs. Any unused space is divided
evenly between cells for which expand is true.
The Gtk.CellRenderer.
true if cell is to be given extra space allocated to tree_column.
Packs the cell into the beginning of the column. If expand is false, then
the cell is allocated no more space than it needs. Any unused space is divided
evenly between cells for which expand is true.
The Gtk.CellRenderer.
true if cell is to be given extra space allocated to tree_column.
Flags the column, and the cell renderers added to this column, to have their sizes renegotiated.
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().

Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Sets multiple properties of an object at once. The properties argument should be a dictionary mapping property names to values.

Sets the alignment of the title or custom widget inside the column header. The alignment determines its location inside the button -- 0.0 for left, 0.5 for center, 1.0 for right.
The alignment, which is between [0.0 and 1.0] inclusive.
Sets the Gtk.TreeCellDataFunc to use for the column. This
function is used instead of the standard attributes mapping for
setting the column value, and should set the value of tree_column's
cell renderer as appropriate. func may be null to remove an
older one.
Optionalfunc: Gtk.TreeCellDataFuncThe Gtk.TreeCellDataFunc to use.
Sets the header to be active if clickable is true. When the header is
active, then it can take keyboard focus, and can be clicked.
true if the header is active.
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 column to take available extra space. This space is shared equally
amongst all columns that have the expand set to true. If no column has this
option set, then the last column gets all extra space. By default, every
column is created with this false.
Along with “fixed-width”, the “expand” property changes when the column is resized by the user.
true if the column should expand to fill available space.
If fixed_width is not -1, sets the fixed width of tree_column; otherwise
unsets it. The effective value of fixed_width is clamped between the
minimum and maximum width of the column; however, the value stored in the
“fixed-width” property is not clamped. If the column sizing is
#GTK_TREE_VIEW_COLUMN_GROW_ONLY or #GTK_TREE_VIEW_COLUMN_AUTOSIZE, setting
a fixed width overrides the automatically calculated width. Note that
fixed_width is only a hint to GTK+; the width actually allocated to the
column may be greater or less than requested.
Along with “expand”, the “fixed-width” property changes when the column is resized by the user.
The new fixed width, in pixels, or -1.
Sets the maximum width of the tree_column. If max_width is -1, then the
maximum width is unset. Note, the column can actually be wider than max
width if it’s the last column in a view. In this case, the column expands to
fill any extra space.
The maximum width of the column in pixels, or -1.
Sets the minimum width of the tree_column. If min_width is -1, then the
minimum width is unset.
The minimum width of the column in pixels, or -1.
Sets the name of the buildable object.

If reorderable is true, then the column can be reordered by the end user

true, if the column can be reordered.
If resizable is true, then the user can explicitly resize the column by
grabbing the outer edge of the column button. If resizable is true and
sizing mode of the column is #GTK_TREE_VIEW_COLUMN_AUTOSIZE, then the sizing
mode is changed to #GTK_TREE_VIEW_COLUMN_GROW_ONLY.
true, if the column can be resized
Sets the growth behavior of tree_column to type.
Sets the logical sort_column_id that this column sorts on when this column
is selected for sorting. Doing so makes the column header clickable.
The sort_column_id of the model to sort on.
Call this function with a setting of true to display an arrow in
the header button indicating the column is sorted. Call
gtk_tree_view_column_set_sort_order() to change the direction of
the arrow.
true to display an indicator that the column is sorted
Changes the appearance of the sort indicator.
This does not actually sort the model. Use
gtk_tree_view_column_set_sort_column_id() if you want automatic sorting
support. This function is primarily for custom sorting behavior, and should
be used in conjunction with gtk_tree_sortable_set_sort_column_id() to do
that. For custom models, the mechanism will vary.
The sort indicator changes direction to indicate normal sort or reverse sort.
Note that you must have the sort indicator enabled to see anything when
calling this function; see gtk_tree_view_column_set_sort_indicator().
Sets the spacing field of tree_column, which is the number of pixels to
place between cell renderers packed into it.

Sets the title of the tree_column. If a custom widget has been set, then
this value is ignored.
The title of the tree_column.
Sets the visibility of tree_column.
true if the tree_column is visible.
Sets the widget in the header to be widget. If widget is null, then the
header button is set with a Gtk.Label set to the title of tree_column.

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().

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_Adds an attribute mapping to the list in cell_layout.
The column is the column of the model to get a value from, and the
attribute is the parameter on cell to be set from the value. So for
example if column 2 of the model contains strings, you could have the
“text” attribute of a Gtk.CellRendererText get its values from column 2.

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_Returns the underlying Gtk.CellArea which might be cell_layout
if called on a Gtk.CellArea or might be null if no Gtk.CellArea
is used by cell_layout.
Virtualvfunc_Returns the cell renderers which have been added to cell_layout.
Virtualvfunc_Virtualvfunc_Gets the name of the buildable object.
Gtk.Builder sets the name based on the

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

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_Adds the cell to the end of cell_layout. If expand is false, then the

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.
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.
