zwp_tablet_pad_group_v2.rs

//! a set of buttons, rings and strips
//!
//! A pad group describes a distinct (sub)set of buttons, rings and strips
//! present in the tablet. The criteria of this grouping is usually positional,
//! eg. if a tablet has buttons on the left and right side, 2 groups will be
//! presented. The physical arrangement of groups is undisclosed and may
//! change on the fly.
//!
//! Pad groups will announce their features during pad initialization. Between
//! the corresponding wp_tablet_pad.group event and wp_tablet_pad_group.done, the
//! pad group will announce the buttons, rings and strips contained in it,
//! plus the number of supported modes.
//!
//! Modes are a mechanism to allow multiple groups of actions for every element
//! in the pad group. The number of groups and available modes in each is
//! persistent across device plugs. The current mode is user-switchable, it
//! will be announced through the wp_tablet_pad_group.mode_switch event both
//! whenever it is switched, and after wp_tablet_pad.enter.
//!
//! The current mode logically applies to all elements in the pad group,
//! although it is at clients' discretion whether to actually perform different
//! actions, and/or issue the respective .set_feedback requests to notify the
//! compositor. See the wp_tablet_pad_group.mode_switch event for more details.
