Variants

Begin

multi-finger swipe begin

This event is sent when a multi-finger swipe gesture is detected on the device.

Fields of Begin

serial: u32time: u32surface: Proxy<WlSurface>fingers: u32

Update

multi-finger swipe motion

This event is sent when a multi-finger swipe gesture changes the position of the logical center.

The dx and dy coordinates are relative coordinates of the logical center of the gesture compared to the previous event.

Fields of Update

time: u32dx: f64dy: f64

End

multi-finger swipe end

This event is sent when a multi-finger swipe gesture ceases to be valid. This may happen when one or more fingers are lifted or the gesture is cancelled.

When a gesture is cancelled, the client should undo state changes caused by this gesture. What causes a gesture to be cancelled is implementation-dependent.

Fields of End
