* Drop movement during gesture decayArturo Castro2010-04-151-2/+7
| | | | | | | | | | | With this patch, finger motion is divided into two phases; one attack phase where fingers are added to the trackpad, and one decay phase, where fingers leave the trackpad. The decay delay is set considerably larger than the attack delay. The prime effect is to ignore accidental pointer movement right after a two-finger scroll.

* Delay movement after a finger configuration changeArturo Castro2010-04-151-8/+20
| | | | | | | | | | The current code responds to finger movement immediately after a finger has been placed on the trackpad, even if the touch is accidental. This patch delays the effect of the finger by 70 ms, resulting in fewer accidental movements.

* Keep logical buttons separate from the hardware onesHenrik Rydberg2010-04-151-4/+8
| | | | | | | | | The button extraction currently modifies the MTState buttons, upsetting the semantics in a bad way. This patch adds the logical button state to the Memory structure, and uses it to compute the logical button change. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Only extract movement from identical finger configurationsHenrik Rydberg2010-04-151-16/+21
| | | | | | | | | The current code would extract movement from a rapid change from one finger to the next, resulting in unwanted jumps. This patch first checks that the finger configuration is the same before attempting to extract movement. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Reorganize gesture codeHenrik Rydberg2010-04-151-18/+32
| | | | | | | Break out extraction of movement, buttons and type. Only code traversal, no logical changes. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Introduce the MTStateHenrik Rydberg2010-04-151-11/+12
| | | | | | | | | | | | | | | The HWState keeps, for good reason, both touching fingers and fingers going away. However, this implies that additional logic is needed to keep track of the number of actual touching fingers. In particular the test for touching fingers is somewhat misplaced in hwstate.c. Moreover, HWState should only exist in one instance, since it contains data which does not need to be referred to during gesture extraction. This patch introduces the MTState structure, which keeps more digested data for gesture extraction. In particular, it only keeps the actual touches.

* Rename State to HWStateHenrik Rydberg2010-04-151-11/+11
| | | | | | | Rename the hardware state struct State to HWState, to make room for additional state structures. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
