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

Requests the compositor to use the provided feedback string associated with this button. This request should be issued immediately after a wp_tablet_pad_group.mode_switch event from the corresponding group is received, or whenever a button 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 each button, and compositors may use this information to offer visual feedback on the button layout (e.g. on-screen displays).

Button indices start at 0. Setting the feedback string on a button that is reserved by the compositor (i.e. not belonging to any wp_tablet_pad_group) does not generate an error but the compositor is free to ignore the request.

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 button. Requests providing other serials than the most recent one will be ignored.

Fields

button: u32

button index

description: String

button description

serial: u32

serial of the mode switch event

Destroy

destroy the pad object

Destroy the wp_tablet_pad object. Objects created from this object are unaffected and should be destroyed separately.

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