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

Fix problem with tap properties at touch release -again

2011-03-24T19:34:20+00:00

This problem was fixed in the early grail stages, and reappeared in Aug 2010, in commit 241c5ec0. This one-liner fixes the problem, because the only interesting update to the properties state at maximum number of fingers is the end time. Signed-off-by: Henrik Rydberg

Reset tap state after timeout

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

A touch and hold will not properly reset the tap state, such that the next tap fails to register. Fixed with this patch. Signed-off-by: Henrik Rydberg

Fix tap event leakage

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

As an earlier stabilizing measure, very short taps were not registered as such but discarded, potentially letting the touch information through as non-gesture events. This should rather be handled in utouch-frame, and thus the code his dropped here. [rydberg@euromail.se: folded in unused code removal] Signed-off-by: Chase Douglas 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 tap state to the tapping model

2010-09-21T10:56:17+00:00

Add the ability to read off the tap state in the tapping model. Useful for emulation i lieu of tapping gestures. Signed-off-by: Henrik Rydberg

Do not tap when leaving fingers on the pad

2010-09-21T10:56:17+00:00

The current code will treat a 3-down-2-up as a tap. This patch changes the logic so that taps are only emitted when the number of fingers returns to the baseline. Signed-off-by: Henrik Rydberg

Inhibit taps immediately after a finger is lifted

2010-09-10T12:06:10+00:00

The intentional tap starts with a finger in the air. This patch treats the sequence up-down-up as unintentional, unless performed with a single finger. Fixes the problem with accidental taps during multi-finger gestures. Signed-off-by: Henrik Rydberg

Cancel tapping also on zoom events

2010-09-09T19:05:11+00:00

The current code cancels tapping when dragging is active. This patch adds zooming to the set, to inhibit tapping also when a perfect zoom without dragging is performed. Reported-by: Chase Douglas Signed-off-by: Henrik Rydberg
