 * \since 6.3
 * \brief Provides a shell extension for Qt applications running on a Qt Wayland Compositor.
 *
 * The QtShell extension provides a way to associate an QtShellSurface with a regular Wayland
 * surface. The QtShell extension is written to support the window management features which are
 * supported by Qt. It may be suitable on a platform where both the compositor and client
 * applications are written with Qt, and where applications are trusted not to abuse features such
 * as manual window positioning and "bring-to-front".
 *
 * For other use cases, consider using IviApplication or XdgShell instead.
 *
 * \code
 * import QtWayland.Compositor.QtShell
 *
 * WaylandCompositor {
 *     property ListModel shellSurfaces: ListModel {}
 *     QtShell {
 *         onQtShellSurfaceCreated: {
 *              shellSurfaces.append({shellSurface: qtShellSurface})
 *         }
 *     }
