Class ATContext

java.lang.Object

org.javagi.base.ProxyInstance

org.gnome.gobject.TypeInstance

org.gnome.gobject.GObject

org.gnome.gtk.ATContext

All Implemented Interfaces:

Proxy

Direct Known Subclasses:

ATContext.ATContext$Impl

@Generated("org.javagi.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 instance for the provided memory address.

Parameters:

address - the memory address of the native object

ATContext

public ATContext()

Create a new ATContext.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ATContext class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ATContext asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class GObject

Returns:

the instance as if it were its parent type

create

public static @Nullable 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(ATContext.StateChangeCallback).
