public class ATContext
extends Object

`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`.

getClassHandler

public static ClassHandler getClassHandler()

createATContext

public static ATContext createATContext(int accessible_role,
 @Nonnull
 Accessible accessible,
 @Nonnull
 Display display)

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:

accessible_role - the accessible role used by the `GtkATContext`

accessible - the `GtkAccessible` implementation using the `GtkATContext`

display - the `GdkDisplay` used by the `GtkATContext`

Returns:

the `GtkATContext`

getAccessible

public Accessible getAccessible()

Retrieves the `GtkAccessible` using this context.

Returns:

a `GtkAccessible`

getAccessibleRole

public int getAccessibleRole()

Retrieves the accessible role of this context.

Returns:

a `GtkAccessibleRole`

onStateChange

public SignalHandler onStateChange(ATContext.OnStateChange signal)

Connect to signal "state-change".
See ATContext.OnStateChange.onStateChange() for signal description.
Field SIGNAL_ON_STATE_CHANGE contains original signal name and can be used as resource reference.

Parameters:

signal - callback function (lambda).

Returns:

SignalHandler. Can be used to disconnect signal and to release callback function.
