Class Details¶

class Gtk.ATContext(**kwargs)¶

Bases:: GObject.Object
Abstract:: Yes
Structure:: Gtk.ATContextClass

GtkATContext is an abstract class provided by GTK to communicate to platform-specific assistive technologies API.

Each platform supported by GTK implements a GtkATContext subclass, and is responsible for updating the accessible state in response to state changes in GtkAccessible.

classmethod create(accessible_role, accessible, display)[source]¶

Parameters:

accessible_role (Gtk.AccessibleRole) – the accessible role used by the GtkATContext
accessible (Gtk.Accessible) – the GtkAccessible implementation using the GtkATContext
display (Gdk.Display) – the GdkDisplay used by the GtkATContext

Returns:

the GtkATContext

Return type:

Gtk.ATContext or None

Creates a new GtkATContext instance for the given accessible role, accessible instance, and display connection.

The GtkATContext implementation being instantiated will depend on the platform.

get_accessible()[source]¶

Returns:: a GtkAccessible
Return type:: Gtk.Accessible

Retrieves the GtkAccessible using this context.

get_accessible_role()[source]¶

Returns:: a GtkAccessibleRole
Return type:: Gtk.AccessibleRole

Retrieves the accessible role of this context.

Signal Details¶

Gtk.ATContext.signals.state_change(a_t_context)¶

Signal Name:: state-change
Flags:: RUN_FIRST
