Enum wayland_protocols::unstable::tablet::v2::server::zwp_tablet_pad_v2::Request [−][src]
#[non_exhaustive] pub enum Request { SetFeedback { button: u32, description: String, serial: u32, }, Destroy, }
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
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 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.
