详细描述

The XdgShell extension provides a way to associate a XdgToplevel or XdgPopup 与常规 Waylnd 表面。使用 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:

import QtWayland.Compositor.XdgShell
WaylandCompositor {
    XdgShell {
        // ...
    }
}
