grail.git/src, branch v1.0.15

Only support pure absolute devices at this time

2010-09-28T09:28:45+00:00

There are some hybrid relative/absolute devices out there, like the magic mouse, for which special behavior, outside the current scope of grail, is expected. This patch disables grail for those devices. 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

Add tap emulation

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

Touchscreens always emit a button event when touching the screen. Trackpads, however, are considered hovering while touching the pad, and instead uses taps to emits button events, which is traditionally implemented elsewhere, and thus leaves a functionality discrepancy. This patch adds tap emulation to grail, utilizing gesture engine. Signed-off-by: Henrik Rydberg

Split pointer status and report status

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

Separate out reporting of the touch state, such that reporting can be deferred. Does not introduce any logic changes. 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

bug: Only report position change events

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

This bug was introduced in v1.0.11. Only report events when the pointer position is actually changing. Signed-off-by: Henrik Rydberg

Reorganize input event emulation code

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

Inject the emulated events into the event buffer instead, and move the pointer logic into the emulation handler. Introduces no logical changes, but reveals the bug in the position event frequency. Signed-off-by: Henrik Rydberg

Move input event filter from tail side to head side

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

There is no need to buffer events that will be ignored later on, so move the event filter to the upstream side. This also allows the event buffer to be used for injected events. Signed-off-by: Henrik Rydberg

Simplify book-keeping of active gestures

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

The current frame computation returns the event types to filter, which is less useful than knowing what gesture types are active in the frame. Add the active gesture types to the frame struct and simplify usage. Signed-off-by: Henrik Rydberg

Allow slow tapping

2010-09-10T12:06:12+00:00

For the benefit of hardware that cannot accurately meet the desirable response times, allow for tapping times up to 300 ms. Signed-off-by: Henrik Rydberg
