Detailed Description

\qmltype XdgShell \instantiates QWaylandXdgShell \inqmlmodule QtWayland.Compositor.XdgShell

Since
5.12

Provides an extension for desktop-style user interfaces.

The XdgShell extension provides a way to associate a XdgToplevel or XdgPopup with a regular Wayland surface. Using the XdgToplevel interface, the client can request that the surface is resized, moved, and so on.

XdgShell corresponds to the Wayland interface, xdg_shell.

To provide the functionality of the shell extension in a compositor, create an instance of the XdgShell component and add it to the list of extensions supported by the compositor:

\qml import QtWayland.Compositor.XdgShell

WaylandCompositor { XdgShell { // ... } } \endqml

\inmodule QtWaylandCompositor
