QWaylandCompositorExtension::QWaylandCompositorExtension()

Creates a QWaylandCompositorExtension with no container.

See also setExtensionContainer().

QWaylandCompositorExtension::QWaylandCompositorExtension(QWaylandObject *container)

Creates a QWaylandCompositorExtension and adds it to the extension container. The container does not become the parent of the QWaylandCompositorExtension.

The extension adds itself to container later, when initialize() is called. For this to happen automatically, an event loop must be running in the current thread.

The QWaylandCompositorExtension will remove itself again when it is destroyed.

QWaylandObject *QWaylandCompositorExtension::extensionContainer() const

Returns the extension container for this QWaylandCompositorExtension or null if none has been set.

See also setExtensionContainer().

[pure virtual] const struct wl_interface *QWaylandCompositorExtension::extensionInterface() const

A pure virtual function which should be reimplemented to return the wl_interface which corresponds to this QWaylandCompositorExtension.

[virtual] void QWaylandCompositorExtension::initialize()

Initializes the QWaylandCompositorExtension. The default implementation adopts the parent object as extension container if none has been set, and if the parent inherits from QWaylandObject. The default implementation also adds the QWaylandCompositorExtension to the list of extensions managed by the extension container.

Override this function in subclasses to provide custom initialization code.

void QWaylandCompositorExtension::setExtensionContainer(QWaylandObject *container)

Sets the extension container for this QWaylandCompositorExtension to container. This must be called before initialize() and cannot be changed once the QWaylandCompositorExtension has been initialized.
