This global offers an alternative, optional way to set cursor images. This
new way uses enumerated cursors instead of a wl_surface like
wl_pointer.set_cursor does.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.

Destructor
Request

The device cursor shape remains unchanged.
set device cursor to the shape
Request
Since Version 1
Sets the device cursor to the specified shape. The compositor will
change the cursor image based on the specified shape.
The cursor actually changes only if the input device focus is one of
the requesting client's surfaces. If any, the previous cursor image
(surface or shape) is replaced.
The "shape" argument must be a valid enum entry, otherwise the
invalid_shape protocol error is raised.
This is similar to the wl_pointer.set_cursor and
zwp_tablet_tool_v2.set_cursor requests, but this request accepts a
shape instead of contents in the form of a surface. Clients can mix
set_cursor and set_shape requests.
The serial parameter must match the latest wl_pointer.enter or
zwp_tablet_tool_v2.proximity_in serial number sent to the client.
Otherwise the request will be ignored.
| Argument | Type | Description |
|---|
| serial | uint | serial number of the enter event |
| shape | uint<shape> | |
This enum describes cursor shapes.
The names are taken from the CSS W3C specification:
https://w3c.github.io/csswg-drafts/css-ui/#cursor
with a few additions.
Note that there are some groups of cursor shapes that are related:
The first group is drag-and-drop cursors which are used to indicate
the selected action during dnd operations. The second group is resize
cursors which are used to indicate resizing and moving possibilities
on window borders. It is recommended that the shapes in these groups
should use visually compatible images and metaphors.
