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.

SetFeedback

set compositor feedback

Request that the compositor use the provided feedback string associated with this ring. This request should be issued immediately after a wp_tablet_pad_group.mode_switch event from the corresponding group is received, or whenever the ring is mapped to a different action. See wp_tablet_pad_group.mode_switch for more details.

Clients are encouraged to provide context-aware descriptions for the actions associated with the ring; compositors may use this information to offer visual feedback about the button layout (eg. on-screen displays).

The provided string 'description' is a UTF-8 encoded string to be associated with this ring, and is considered user-visible; general internationalization rules apply.

The serial argument will be that of the last wp_tablet_pad_group.mode_switch event received for the group of this ring. Requests providing other serials than the most recent one will be ignored.

Fields of SetFeedback

description: Stringserial: u32

Destroy

destroy the ring object

This destroys the client's resource for this ring object.

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