Variants (Non-exhaustive)

This enum is marked as 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

Fields

button: u32

button index

description: String

button description

serial: u32

serial of the mode switch event

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.

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 sent this object cannot be used any longer.
