QWaylandCompositorExtension is the base class for implementing Wayland extensions on the compositor-side of the connection. If no other extension container is explicitly set, it will automatically add itself to its parent object, granted that this inherits from QWaylandObject .
For example, for registering global extensions, you can inherit from QWaylandCompositorExtension and pass the QWaylandCompositor object as extension container.

Creates a QWaylandCompositorExtension with no container.
另请参阅 setExtensionContainer ().
Creates a QWaylandCompositorExtension and adds it to the extension container 。 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.
Returns the extension container for this QWaylandCompositorExtension or null if none has been set.

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
()
初始化 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.
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.
