|

A global interface to provide semantic touchpad gestures for a given
|
||||
pointer.
|
||||
|
||||
Two gestures are currently supported: swipe and zoom/rotate.
|
||||
All gestures follow a three-stage cycle: begin, update, end and
|
||||
are identified by a unique id.
|
||||
|
||||
Warning! The protocol described in this file is experimental and
|
||||
backward incompatible changes may be made. Backward compatible changes
|
||||
may be added together with the corresponding interface version bump.
|
||||
Backward incompatible changes are done by bumping the version number in
|
||||
the protocol and interface names and resetting the interface version.
|
||||
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||
version number in the protocol and interface names are removed and the
|
||||
interface version number is reset.

<description summary="a swipe gesture object">
|
||||
A swipe gesture object notifies a client about a multi-finger swipe
|

gesture detected on an indirect input device such as a touchpad.
|
||||
The gesture is usually initiated by multiple fingers moving in the
|
||||
same direction but once initiated the direction may change.

||||
The precise conditions of when such a gesture is detected are
|
||||
implementation-dependent.
|

A gesture consists of three stages: begin, update (optional) and end.
|
||||
There cannot be multiple simultaneous 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.

This event is sent when a multi-finger pinch gesture changes the

position of the logical center, the rotation or the relative scale.

|

The dx and dy coordinates are relative coordinates in the
|

surface coordinate space of the logical center of the gesture.
|
||||
|
||||
The scale factor is an absolute scale compared to the
|

pointer_gesture_pinch.begin event, e.g. a scale of 2 means the fingers
|
||||
are now twice as far apart as on pointer_gesture_pinch.begin.
|
||||
|
||||
The rotation is the relative angle in degrees clockwise compared to the previous
|
||||
pointer_gesture_pinch.begin or pointer_gesture_pinch.update event.
