Detailed Description

\qmltype WaylandCompositor \nativetype QWaylandCompositor \inqmlmodule QtWayland.Compositor

Since: 5.8

Manages the Wayland display server.

The WaylandCompositor manages the connections to the clients, as well as the different \l{WaylandOutput}{outputs} and \l{QWaylandSeat}{seats}.

Normally, a compositor application will have a single WaylandCompositor instance, which can have several outputs as children. When a client requests the compositor to create a surface, the request is handled by the onSurfaceRequested handler.

Extensions that are supported by the compositor should be instantiated and added to the extensions property or simply as direct children of WaylandCompositor.

If this is not possible, reimplement this function in your compositor subclass to implement custom logic. The default implementation only grabs shared memory and OpenGL buffers, reimplement this in your compositor subclass to handle more buffer types.

◆ retainedSelection

bool QWaylandCompositor::retainedSelection

readwrite

\qmlproperty bool QtWayland.Compositor::WaylandCompositor::retainedSelection \default false

This property controls whether the compositor retains a copy of clipboard selection data. When true, the compositor eagerly reads and caches all clipboard data from the owning client. This incurs a performance cost.

◆ socketName

\qmlproperty string QtWayland.Compositor::WaylandCompositor::socketName

This property holds the socket name used by WaylandCompositor to communicate with clients. It must be set before the component is completed.

If the socketName is empty (the default), the contents of the start argument --wayland-socket-name are used instead. If the argument is not set, the compositor tries to find a socket name, which is {wayland-0} by default.
