Update copyright information

2011-04-28T16:43:16+00:00

The license information was always right, but the copyright information for this particular project was never quite right. Corrected with this patch. No functional changes. Signed-off-by: Henrik Rydberg

Convert to utouch-frame mapping

2011-04-04T17:46:29+00:00

Remove the grail-internal mapping code and rely directly on utouch-frame instead. Passes the unit test designed for this change. Signed-off-by: Henrik Rydberg

Decouple timeout from discard

2011-03-28T20:02:11+00:00

Move the actual gesture discard from the recognition phase to the instantiation phase. Signed-off-by: Henrik Rydberg

Make reset logic of pinch and drag same as for drag

2011-03-14T11:55:20+00:00

There is no direct reason for one-fingered pinch/rotate gestures to be discarded immediately, so only reset gestures on touch down, as for drags. Signed-off-by: Henrik Rydberg

Introduce gesture timeouts

2011-03-14T11:55:19+00:00

The timeout of a gesture is integral to the gesture type. This patch introduces timeout per gesture type, potentially enabling more control over gesture timing aspects. The timeout logic replaces the recently added recognition state. Signed-off-by: Henrik Rydberg

Replace touch logic with utouch frame engine

2011-01-02T11:39:07+00:00

The original grail uses an internal touch framework and exports some touch information as extended attributes to gesture events. This was never quite the intention, but rather to expose gestures and touches on a similar footing, such that grail can be input agnostic. This patch starts off by replacing the internal touch framework with the utouch-frame engine. Signed-off-by: Henrik Rydberg

Add contact information to the property list

2010-08-19T20:15:55+00:00

Add the five first contacts to the property list, and unify the handling of all gesture types in this regard. To avoid duplication, move the scaling of properties closer to the gesture recognizer. Move all gesture event handling code to grail-event.c, simplifying the structure somewhat. Signed-off-by: Henrik Rydberg

split out bounding box computation

Add environment and meta gestures

2010-08-11T16:59:29+00:00

With meta gestures, the gesture starts given a certain number of fingers, but can then continue even if the number of fingers change. By configuration, such gestures live on a different priority plane from normal gestures. To match window manager specs, this patch adds the environment and meta planes, and add drag, pinch and rotate gestures initiated with three and four fingers, respectively.
