Struct ZwpTabletPadDialV2

pub struct ZwpTabletPadDialV2 { /* private fields */ }

Available on crate feature wayland and Linux only.

pad dial

A rotary control, e.g. a dial or a wheel.

Events on a dial are logically grouped by the zwp_tablet_pad_dial_v2.frame event.

See also the Event enum for this interface.

Implementations

impl ZwpTabletPadDialV2

pub fn set_feedback(&self, description: String, serial: u32)

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.

pub fn destroy(&self)

destroy the dial object

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