Class
GtkAccessible
Description [src]
class Gtk.Accessible : Atk.Object
{
/* No available fields */
}
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: 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.
since: 2.22

Signals
Signals inherited from AtkObject (8)
AtkObject::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.
AtkObject::announcement
The “announcement” signal can be emitted to pass an announcement on to be read by a screen reader.
AtkObject::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”.
AtkObject::focus-event
The signal “focus-event” is emitted when an object gained or lost focus.
AtkObject::notification
The “notification” signal can be emitted to pass an announcement on to be read by a screen reader.
AtkObject::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.
AtkObject::state-change
The “state-change” signal is emitted when an object’s state changes. The detail value identifies the state type which has changed.
AtkObject::visible-data-changed
The “visible-data-changed” signal is emitted when the visual appearance of the object changed.
Signals inherited from GObject (1)
GObject::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.
