Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

remove sub-surface interface

The sub-surface interface is removed from the wl_surface object that was turned into a sub-surface with a wl_subcompositor.get_subsurface request. The wl_surface’s association to the parent is deleted. The wl_surface is unmapped immediately.

This is a destructor, once sent this object cannot be used any longer.

SetPosition

reposition the sub-surface

This sets the position of the sub-surface, relative to the parent surface.

The sub-surface will be moved so that its origin (top left corner pixel) will be at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative values are allowed.

The initial position is 0, 0.

Position is double-buffered state on the parent surface, see wl_subsurface and wl_surface.commit for more information.

Fields

x: i32

x coordinate in the parent surface

y: i32

y coordinate in the parent surface

PlaceAbove

restack the sub-surface

This sub-surface is taken from the stack, and put back just above the reference surface, changing the z-order of the sub-surfaces. The reference surface must be one of the sibling surfaces, or the parent surface. Using any other surface, including this sub-surface, will cause a protocol error.

A new sub-surface is initially added as the top-most in the stack of its siblings and parent.

Z-order is double-buffered state on the parent surface, see wl_subsurface and wl_surface.commit for more information.

Fields

sibling: WlSurface

the reference surface

PlaceBelow

restack the sub-surface

The sub-surface is placed just below the reference surface.

See wl_subsurface.place_above.

Fields

sibling: WlSurface

the reference surface

SetSync

set sub-surface to synchronized mode

Change the commit behaviour of the sub-surface to synchronized mode.

See wl_subsurface and wl_surface.commit for more information.

SetDesync

set sub-surface to desynchronized mode

Change the commit behaviour of the sub-surface to desynchronized mode.

See wl_subsurface and wl_surface.commit for more information.
