Class

GtkAccessible

Description [src]

class Gtk.Accessible : Atk.Object {
  parent: AtkObject
}

The GtkAccessible class is the base class for accessible implementations for GtkWidget subclasses. It is a thin wrapper around AtkObject, which adds facilities for associating a widget with its accessible object.

An accessible implementation for a third-party widget should derive from GtkAccessible and implement the suitable interfaces from ATK, such as AtkText or AtkSelection. To establish the connection between the widget class and its corresponding acccessible implementation, override the get_accessible vfunc in GtkWidgetClass.

Instance methods

gtk_accessible_connect_widget_destroyed

This function specifies the callback function to be called when the widget corresponding to a GtkAccessible is destroyed.

Deprecated since: 3.4

gtk_accessible_get_widget

Gets the GtkWidget corresponding to the GtkAccessible. The returned widget does not have a reference added, so you do not need to unref it.

Available since: 2.22

gtk_accessible_set_widget

Sets the GtkWidget corresponding to the GtkAccessible.

Available since: 2.22

Signals

Signals inherited from AtkObject (6)
Atk.Object::active-descendant-changed

The “active-descendant-changed” signal is emitted by an object which has the state ATK_STATE_MANAGES_DESCENDANTS when the focus object in the object changes. For instance, a table will emit the signal when the cell in the table which has focus changes.

Atk.Object::children-changed

The signal “children-changed” is emitted when a child is added or removed form an object. It supports two details: “add” and “remove”

Atk.Object::focus-event

The signal “focus-event” is emitted when an object gained or lost focus.

Deprecated since: 2.9.4

Atk.Object::property-change

The signal “property-change” is emitted when an object’s property value changes. arg1 contains an AtkPropertyValues with the name and the new value of the property whose value has changed. Note that, as with GObject notify, getting this signal does not guarantee that the value of the property has actually changed; it may also be emitted when the setter of the property is called to reinstate the previous value.

Atk.Object::state-change

The “state-change” signal is emitted when an object’s state changes. The detail value identifies the state type which has changed.

Atk.Object::visible-data-changed

The “visible-data-changed” signal is emitted when the visual appearance of the object changed.

Signals inherited from GObject (1)
GObject.Object::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
