Protocol for grabbing the keyboard from Xwayland
This protocol is application-specific to meet the needs of the X11 protocol through Xwayland. It provides a way for Xwayland to request all keyboard events to be forwarded to a surface even when the surface does not have keyboard focus.
In the X11 protocol, a client may request an “active grab” on the keyboard. On success, all key events are reported only to the grabbing X11 client. For details, see XGrabKeyboard(3).
The core Wayland protocol does not have a notion of an active keyboard grab. When running in Xwayland, X11 applications may acquire an active grab inside Xwayland but that cannot be translated to the Wayland compositor who may set the input focus to some other surface. In doing so, it breaks the X11 client assumption that all key events are reported to the grabbing client.
This protocol specifies a way for Xwayland to request all keyboard be directed to the given surface. The protocol does not guarantee that the compositor will honor this request and it does not prescribe user interfaces on how to handle the respond. For example, a compositor may inform the user that all key events are now forwarded to the given client surface, or it may ask the user for permission to do so.
Compositors are required to restrict access to this application specific protocol to Xwayland alone.
