— context object for Xwayland shell
xwayland_shell_v1 is a singleton global object that provides the ability to create a xwayland_surface_v1 object for a given wl_surface.
This interface is intended to be bound by the Xwayland server.
A compositor must not allow clients other than Xwayland to bind to this interface. A compositor should hide this global from other clients' wl_registry. A client the compositor does not consider to be an Xwayland server attempting to bind this interface will result in an implementation-defined error.
An Xwayland server that has bound this interface must not set the `WL_SURFACE_ID` atom on a window.
— destroy the Xwayland shell object
Destroy the xwayland_shell_v1 object.
The child objects created via this interface are unaffected.
— assign the xwayland_surface surface role
Create an xwayland_surface_v1 interface for a given wl_surface object and gives it the xwayland_surface role. It is illegal to create an xwayland_surface_v1 for a wl_surface which already has an assigned role and this will result in the `role` protocol error.
See the documentation of xwayland_surface_v1 for more details about what an xwayland_surface_v1 is and how it is used.
role: given wl_surface has another role
— interface for associating Xwayland windows to wl_surfaces
An Xwayland surface is a surface managed by an Xwayland server. It is used for associating surfaces to Xwayland windows.
The Xwayland server associated with actions in this interface is determined by the Wayland client making the request.
The client must call wl_surface.commit on the corresponding wl_surface for the xwayland_surface_v1 state to take effect.
— associates a Xwayland window to a wl_surface
Associates an Xwayland window to a wl_surface. The association state is double-buffered and will be applied at the time wl_surface.commit of the corresponding wl_surface is called.
The `serial_lo` and `serial_hi` parameters specify a non-zero monotonic serial number which is entirely unique and provided by the Xwayland server equal to the serial value provided by a client message with a message type of the `WL_SURFACE_SERIAL` atom on the X11 window for this surface to be associated to.
The serial value in the `WL_SURFACE_SERIAL` client message is specified as having the lo-bits specified in `l` and the hi-bits specified in `l`.
If the serial value provided by `serial_lo` and `serial_hi` is not valid, the `invalid_serial` protocol error will be raised.
An X11 window may be associated with multiple surfaces throughout its lifespan. (eg. unmapping and remapping a window). For each wl_surface, this state must not be committed more than once, otherwise the `already_associated` protocol error will be raised.
uint: The lower 32-bits of the serial number associated with the X11 window
uint: The upper 32-bits of the serial number associated with the X11 window
— destroy the Xwayland surface object
Destroy the xwayland_surface_v1 object.
Any already existing associations are unaffected by this action.
already_associated: given wl_surface is already associated with an X11 window
invalid_serial: serial was not valid
