The wl_surface.commit request atomically + applies all pending state, replacing the current state. After commit, the + new pending state is as documented for each related request. + + + + + Requests that the compositor anchor the surface to the specified edges + and corners. If two orthoginal edges are specified (e.g. 'top' and + 'left'), then the anchor point will be the intersection of the edges + (e.g. the top left corner of the output); otherwise the anchor point + will be centered on that edge, or in the center if none is specified. + + Anchor is double-buffered, see wl_surface.commit. + + + + + + + Requests that the compositor avoids occluding an area of the surface + with other surfaces. The compositor's use of this information is + implementation-dependent - do not assume that this region will not + actually be occluded. + + This value is only meaningful if the surface is anchored to an edge, + rather than a corner. The zone is the number of pixels from the edge + that are considered exclusive. + + Exclusive zone is double-buffered, see wl_surface.commit. + + + + + + + Requests that the surface be placed some distance away from the anchor + point on the output, in pixels. Setting this value for edges you are + not anchored to has no effect. + + Margin is double-buffered, see wl_surface.commit. + + + + + + + + + + This assigns an xdg_popup's parent to this layer_surface.

If the client picks a smaller size and + is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the + surface will be centered on this axis. + + If the width or height arguments are zero, it means the client should + decide its own window dimension. + + + + + + + + + + + + + + + + + + + + + + Clients can use this interface to specify input semantics for a layer + surface on a given seat.
