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

unbind from the subcompositor interface

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wl_subsurface objects included.

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

GetSubsurface

Fields

surface: WlSurface

the surface to be turned into a sub-surface

parent: WlSurface

the parent surface

give a surface the role sub-surface

Create a sub-surface interface for the given surface, and associate it with the given parent surface. This turns a plain wl_surface into a sub-surface.

The to-be sub-surface must not already have another role, and it must not have an existing wl_subsurface object. Otherwise the bad_surface protocol error is raised.

Adding sub-surfaces to a parent is a double-buffered operation on the parent (see wl_surface.commit). The effect of adding a sub-surface becomes visible on the next time the state of the parent surface is applied.

The parent surface must not be one of the child surface’s descendants, and the parent must be different from the child surface, otherwise the bad_parent protocol error is raised.

This request modifies the behaviour of wl_surface.commit request on the sub-surface, see the documentation on wl_subsurface interface.
