a hold gesture object

A hold gesture object notifies a client about a single- or multi-finger hold gesture detected on an indirect input device such as a touchpad. The gesture is usually initiated by one or more fingers being held down without significant movement. The precise conditions of when such a gesture is detected are implementation-dependent.

In particular, this gesture may be used to cancel kinetic scrolling.

A hold gesture consists of two stages: begin and end. Unlike pinch and swipe there is no update stage. There cannot be multiple simultaneous hold, pinch or swipe gestures on a same pointer/seat, how compositors prevent these situations is implementation-dependent.

A gesture may be cancelled by the compositor or the hardware. Clients should not consider performing permanent or irreversible actions until the end of a gesture has been received.
