In Qt 6.5, a QNativeInterface::QWaylandApplication interface will be added for direct access to native Wayland objects used in Qt's internal structures, as well as for retrieving information about the user's most recent actions, which may be required for passing to Wayland protocol extensions. The new interface is implemented in the QNativeInterface namespace, which also provides calls to access the native APIs for X11 and Android platforms. In the future, additional QWaylandWindow interfaces for low-level access to windows and QWaylandScreen for output access (wl_output) are expected, which are currently positioned as experimental and hidden within the QNativeInterface::Private area.
