** Description changed:
+ Feature Freeze Exception:
+
+ The current uTouch stack does not have any gesture events that fire when
+ touches begin. Touches must move to cross a threshold before emitting
+ any events. However, gestures on touch begin is a necessary
+ functionality for Natty Unity work. The related branches include the
+ addition of a new "touch" gesture type.
+
When Unity doesn't get an init signal from GEIS we simply cannot perform
any actions when the user presses but has not yet performed a gesture.
Several touch specifications call for such behavior, these include:
- * 3 finger touch to show the window handles
- * alt-tab
- * tap then hold
+ * 3 finger touch to show the window handles
+ * alt-tab
+ * tap then hold
(among others).
- The most critical of these is 3 finger touch to show the window handles
+ The most critical of these is 3 finger touch to show the window handles.
+
+ This new code is in ppa:utouch-team/unstable and is being actively used
+ and developed against by the Unity team.
+
+ The changes necessitate enlarging the event type bitmask inside geis, so
+ regression risk is small but non-trivial. The addition of the touch
+ gesture itself is an ABI addition (no API changes, and no ABI
+ breakages).
