GtkAccessible

GtkAccessible — Accessibility support for widgets

Properties

GtkWidget * widget Read / Write

Types and Values

struct GtkAccessible

Object Hierarchy

    GObject
    ╰── AtkObject
        ╰── GtkAccessible

Includes

#include <gtk/gtk.h>

Description

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.

Functions

gtk_accessible_connect_widget_destroyed ()

void
gtk_accessible_connect_widget_destroyed
                               (GtkAccessible *accessible);

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 called when the widget corresponding to a GtkAccessible is destroyed.

Parameters

accessible

a GtkAccessible

 

gtk_accessible_get_widget ()

GtkWidget *
gtk_accessible_get_widget (GtkAccessible *accessible);

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

Parameters

accessible

a GtkAccessible

 

Returns

pointer to the GtkWidget corresponding to the GtkAccessible, or NULL.

[transfer none]

gtk_accessible_set_widget ()

void
gtk_accessible_set_widget (GtkAccessible *accessible,
                           GtkWidget *widget);

Sets the GtkWidget corresponding to the GtkAccessible.

accessible will not hold a reference to widget . It is the caller’s responsibility to ensure that when widget is destroyed, the widget is unset by calling this function again with widget set to NULL.

Parameters

widget

a GtkWidget or NULL to unset.

[allow-none]
