Detailed Description
This class is part of the QWaylandWlShell extension and provides a way to extend the functionality of an existing QWaylandSurface with features specific to desktop-style compositors, such as resizing and moving the surface.
It corresponds to the Wayland interface wl_shell_surface.

Member Function Documentation
QWaylandWlShellSurface::QWaylandWlShellSurface(QWaylandWlShell *shell, QWaylandSurface *surface, const QWaylandResource &res)
Constructs a QWaylandWlShellSurface for surface and initializes it with the given shell and resource res.
QWaylandWlShellSurface::QWaylandWlShellSurface()
Constructs a QWaylandWlShellSurface.
[slot] void QWaylandWlShellSurface::ping()
Sends a ping event to the client. If the client replies to the event the pong signal will be emitted.
[static] QWaylandWlShellSurface *QWaylandWlShellSurface::fromResource(wl_resource *resource)
Returns the QWaylandWlShellSurface object associated with the given resource, or null if no such object exists.
void QWaylandWlShellSurface::initialize(QWaylandWlShell *shell, QWaylandSurface *surface, const QWaylandResource &resource)
Initializes the QWaylandWlShellSurface and associates it with the given shell, surface, and resource.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
void QWaylandWlShellSurface::sendConfigure(const QSize &size, QWaylandWlShellSurface::ResizeEdge edges)
Sends a configure event to the client, suggesting that it resize its surface to the provided size. The edges provide a hint about how the surface was resized.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
void QWaylandWlShellSurface::sendPopupDone()
Sends a popup_done event to the client to indicate that the user has clicked somewhere outside the client's surfaces.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
