Interface wp_cursor_shape_manager_v1 — cursor shape manager

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.

Request wp_cursor_shape_manager_v1.destroy — destroy the manager

Destroy the cursor shape manager.

Request wp_cursor_shape_manager_v1.get_pointer — manage the cursor shape of a pointer device

Obtain a wp_cursor_shape_device_v1 for a wl_pointer object.

When the pointer capability is removed from the wl_seat, the wp_cursor_shape_device_v1 object becomes inert.

Request wp_cursor_shape_manager_v1.get_tablet_tool_v2 — manage the cursor shape of a tablet tool device

Obtain a wp_cursor_shape_device_v1 for a zwp_tablet_tool_v2 object.

When the zwp_tablet_tool_v2 is removed, the wp_cursor_shape_device_v1 object becomes inert.

Interface wp_cursor_shape_device_v1 — cursor shape for a device

This interface allows clients to set the cursor shape.

Request wp_cursor_shape_device_v1.destroy — destroy the cursor shape device

Destroy the cursor shape device.

The device cursor shape remains unchanged.

Request wp_cursor_shape_device_v1.set_shape — set device cursor to the shape

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.

  • serial uint: serial number of the enter event
  • shape uint: None
