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

Discard tapping even when there are zero events between down and up

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

The current logic assumes there will be at least one frame with between touch up and touch down or the tap will not be properly timed out. Fixed with this patch. Reported-by: Chase Douglas Signed-off-by: Henrik Rydberg

Introduce tapping from any finger configuration

2010-08-26T14:29:01+00:00

The current code only emits taps from zero fingers to N fingers. This patch introduces tapping from any prior finger configuration. A tap is defined as an increased number of fingers followed by a decrease within the tap timeout. A tap is reported as the maximum number of fingers present during the tap sequence.

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

Make tapping position appear properly

Filter abs events by default in grail-gesture

2010-08-10T14:04:18+00:00

Also connect the timeout for press with the timeout of tapping. Signed-off-by: Henrik Rydberg

Add property declarations to grail-types

2010-08-10T14:04:18+00:00

Also add accumulated values for delta and velocity properties. Signed-off-by: Henrik Rydberg

Keep both raw and action delta in move model

2010-08-08T10:05:16+00:00

Accumulated values can be obtained either by using the raw_delta, which is the actual (filtered) change between frames, or by using the action delta, which sums up to the same position, but in a non- linear fashion. Use the raw delta for pointer gestures. Signed-off-by: Henrik Rydberg

Send proper begin/update/end status for gestures

2010-08-07T18:47:56+00:00

For transient gestures like taps, use update only. Signed-off-by: Henrik Rydberg
