Gtk.ATContext¶

class — extends GObject.Object

Communicates with 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
def create(cls, accessible_role: AccessibleRole | int, accessible: Accessible, display: Gdk.Display) -> ATContext | 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.

Parameters:
