Struct TouchGestureArena
pub struct TouchGestureArena { /* private fields */ }Expand description
Resolves taps, pans, multi-finger swipes and pinches from raw direct-touch contacts. It reports continuous pan/pinch updates and at most one terminal tap or swipe. Long-press timing remains a host concern because it needs a frame/timer wake even when no touch event arrives.
Implementations§
§impl TouchGestureArena
impl TouchGestureArena
pub fn new() -> TouchGestureArena
pub fn shell_owns_current(&self) -> bool
pub fn shell_owns_current(&self) -> bool
Once a third contact joins, the whole stream remains shell-owned through every release; ownership must not flicker back to an app when the contact count falls from three to two.
pub fn cancel_all(&mut self)
pub fn cancel_all(&mut self)
Drop every direct-touch contact without producing a terminal gesture. Used when the compositor loses the input source or transfers the whole seat to the lock screen.
pub fn on_touch( &mut self, id: u64, position: Point, phase: GesturePhase, ) -> Vec<TouchGestureEvent>
pub fn contact_count(&self) -> usize
pub fn contact_count(&self) -> usize
Contacts currently down.
