详细描述

QWaylandCompositorExtensionTemplate is a template class which inherits QWaylandCompositorExtension and is convenience for building custom Wayland extensions with Qt.

It provides the connection between Qt Wayland Compositor and the class generated by qtwaylandscanner , based on the XML description of the extension protocol.

It provides two specific pieces of convenience:

• A reimplementation of QWaylandCompositorExtension::extensionInterface () which returns the wl_interface pointer for the qtwaylandscanner-generated base class.
• A static findIn () function which searches for an instance of the extension in a provided container, and returns this if it is found.

Typically, a new extension will dual-inherit QWaylandCompositorExtensionTemplate and the class generated by qtwaylandscanner .

QWaylandCompositorExtensionTemplate should be parameterized with the subclass itself:

class MyExtension
    : public QWaylandCompositorExtensionTemplate<MyExtension>
    , QtWaylandServer::my_extension
					

在此范例中， MyExtension is an implementation of the generated interface my_extension .

成员函数文档编制

[static] T *QWaylandCompositorExtensionTemplate:: findIn ( QWaylandObject * container )

If any instance of the interface has been registered with container , this is returned. Otherwise null is returned. The look-up is based on the generated interfaceName() which matches the interface name in the protocol description.
