Gtk.Accessible

Gtk.Accessible — Accessibility support for widgets

Object Hierarchy:

    GObject
    ╰── AtkObject
        ╰── Gtk.Accessible

Functions:

• connect_widget_destroyed (self)
• get_widget (self) -> Gtk.Widget
• set_widget (self, widget:Gtk.Widget=None)

Description:

The Gtk.Accessible class is the base class for accessible implementations for Gtk.Widget subclasses. It is a thin wrapper around Atk.Object, which adds facilities for associating a widget with its accessible object.

An accessible implementation for a third-party widget should derive from Gtk.Accessible and implement the suitable interfaces from Atk, such as Atk.Text or Atk.Selection. To establish the connection between the widget class and its corresponding acccessible implementation, override the get_accessible vfunc in Gtk.WidgetClass.

Function Details:

connect_widget_destroyed()

connect_widget_destroyed (self)

Gtk.Accessible:connect_widget_destroyed has been deprecated since version 3.4 and should not be used in newly-written code. Use Gtk.Accessible:set_widget() and its vfuncs. This function specifies the callback function to be calledwhen the widget corresponding to a Gtk.Accessible is destroyed.

get_widget (self) -> Gtk.Widget

Gets the Gtk.Widget corresponding to the Gtk.Accessible.The returned widget does not have a reference added, soyou do not need to unref it.
