## Detailed Description

The XdgDecorationManagerV1 extension provides a way for a compositor to announce support for server-side window decorations, and for xdg-shell clients to communicate whether they prefer client-side or server-side decorations.

XdgDecorationManagerV1 corresponds to the Wayland interface, `zxdg_decoration_manager_v1`.

To provide the functionality of the extension in a compositor, create an instance of the XdgDecorationManagerV1 component and add it to the list of extensions supported by the compositor:

     import QtWayland.Compositor

     WaylandCompositor {
         // Xdg decoration manager assumes xdg-shell is being used
         XdgShell {
             onToplevelCreated: // ...
         }
         XdgDecorationManagerV1 {
             // Provide a hint to clients that support the extension they should use server-side
             // decorations.
             preferredMode: XdgToplevel.ServerSideDecoration
         }
     }

## Property Documentation

preferredMode : string

This property holds the decoration mode the compositor prefers.

This is the mode used for clients that don't indicate a preference for server-side or client-side decorations.
