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 dial. This request should be issued immediately after a zwp_tablet_pad_group_v2.mode_switch event from the corresponding group is received, or whenever the dial is mapped to a different action. See zwp_tablet_pad_group_v2.mode_switch for more details.

Clients are encouraged to provide context-aware descriptions for the actions associated with the dial, and 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 zwp_tablet_pad_group_v2.mode_switch event received for the group of this dial. Requests providing other serials than the most recent one will be ignored.

Fields

description: String

dial description

serial: u32

serial of the mode switch event

Destroy

destroy the dial object

This destroys the client’s resource for this dial object.

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