|
|
|
|
|
|
<p>Set the pointer surface, i.e., the surface that contains the
|
|
|
|
|
|
pointer image (cursor). This request gives the surface the role
|
|
|
|
|
|
of a cursor. If the surface already has another role, it raises
|
|
|
|
|
|
a protocol error.</p>
|
|
|
|
|
|
<p>The cursor actually changes only if the pointer
|
|
|
|
|
|
focus for this device is one of the requesting client's surfaces
|
|
|
|
|
|
or the surface parameter is the current pointer surface. If
|
|
|
|
|
|
there was a previous surface set with this request it is
|
|
|
|
|
|
replaced. If surface is NULL, the pointer image is hidden.</p>
|
|
|
|
|
|
<p>The parameters hotspot_x and hotspot_y define the position of
|
|
|
|
|
|
the pointer surface relative to the pointer location. Its
|
|
|
|
|
|
top-left corner is always at (x, y) - (hotspot_x, hotspot_y),
|
|
|
|
|
|
where (x, y) are the coordinates of the pointer location, in
|
|
|
|
|
|
surface-local coordinates.</p>
|
|
|
|
|
|
<p>On surface.attach requests to the pointer surface, hotspot_x
|
|
|
|
|
|
and hotspot_y are decremented by the x and y parameters
|
|
|
|
|
|
passed to the request. Attach must be confirmed by
|
|
|
|
|
|
wl_surface.commit as usual.</p>
|
|
|
|
|
|
<p>The hotspot can also be updated by passing the currently set
|
|
|
|
|
|
pointer surface to this request with new values for hotspot_x
|
|
|
|
|
|
and hotspot_y.</p>
|
|
|
|
|
|
<p>The current and pending input regions of the wl_surface are
|
|
|
|
|
|
cleared, and wl_surface.set_input_region is ignored until the
|
|
|
|
|
|
wl_surface is no longer used as the cursor. When the use as a
|
|
|
|
|
|
cursor ends, the current and pending input regions become
|
|
|
|
|
|
undefined, and the wl_surface is unmapped.</p>

|
|
|
|
|
|
<p>Using this request a client can tell the server that it is not going to
|
|
|
|
|
|
use the pointer object anymore.</p>
|
|
|
|
|
|
<p>This request destroys the pointer proxy object, so clients must not call
|
|
|
|
|
|
wl_pointer_destroy() after using this request.</p>
|
|
|
|
|
|
<p>This is a destructor, you cannot send requests to this object any longer once this method is called.
