 * \title Qt Wayland Compositor Examples - Multi Screen
 * \example multi-screen
 * \brief Multi Screen is a desktop-style Wayland compositor for multiple screens.
 * \ingroup qtwaylandcompositor-examples
 *
 * Multi-screen is a desktop-style Wayland compositor example for multiple
 * screens.
 *
 * When a client creates a shell surface, one ShellSurfaceItem is created on
 * each screen. The ShellSurfaceItem will be visible only on one (or two)
 * screens at a time. ShellSurfaceItem positions are synchronized so that when
 * windows enter one screen they are moved off another at the same time.
 *
 * WaylandQuickItem::setPrimary() is called at appropriate times to set the
 * primary view for the ShellSurface, which is used when the client asks to be
 * maximized or fullscreen.
