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

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

Support legacy devices

2010-09-09T08:17:09+00:00

Simulate MT touch events for legacy devices that support the DOUBLETAP, TRIPLETAP and QUADTAP events. This allows multi-finger tap and drag gestures to be emitted, providing a basic level of MT functionality for legacy devices. Signed-off-by: Henrik Rydberg

Make orientation computation more robust

2010-08-30T00:57:38+00:00

The MT protocol defines the angle to be between -Pi/2 and Pi/2, and expects the defined range to be symmetric around zero. Make the angle computation more robust against varying definitions in the kernel drivers. Signed-off-by: Henrik Rydberg

Simplify touch machinery

2010-08-19T18:03:15+00:00

To be able to model touch information uniformly across all supported devices, the semantics of the touch attributes has to be treated explicitly. Drop the generic touch property array and replace it by an actual structure. In addition, the touch-engine abstraction turned out to not be needed, so drop it as well. Signed-off-by: Henrik Rydberg
