@Generated("io.github.jwharm.JavaGI")
public abstract class ATContext
extends GObject

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.

Constructor Details

ATContext

public ATContext(MemorySegment address)

Create a ATContext proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ATContext

public ATContext()

Creates a new ATContext.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ATContext class

Returns:

the GType

asParent

protected ATContext asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

create

public static ATContext create(AccessibleRole accessibleRole,
 Accessible accessible,
 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:

accessibleRole - 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 AccessibleRole getAccessibleRole()

Retrieves the accessible role of this context.

Returns:

a GtkAccessibleRole

onStateChange

public SignalConnection<ATContext.StateChangeCallback> onStateChange(ATContext.StateChangeCallback handler)

Emitted when the attributes of the accessible for the GtkATContext instance change.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

• ATContext.StateChangeCallback.run()

emitStateChange

public void emitStateChange()

Emits the "state-change" signal. See onStateChange(org.gnome.gtk.ATContext.StateChangeCallback).
