Android: Fix right click getting triggered when stylus isn't moved much
Problem:
If you slightly move the stylus on canvas, Android's gesture detector thinks that this is just a natural jitter and sends long-press "event" (which in turn launches the assigned action, default one being popup palette). In fa7e7016, I modified the platform code to handle long press in a way that we first end (or cancel if available) the previous event (touch/tablet). And then send a right click event. This prevents Qt from immediately firing the highlighted item in context menu.
This resulted in a problem where canvas would show popup palette whenever stylus was moved in a minimal fashion, earlier it didn't happen because when the tablet events were on (as we never ended the event) the mouse events would be blocked.
Solutions:
- Disabling right click for all but touch events for which the Gesture Detector is optimized.
- Tuning the gesture detector to handle stylus events as well.
- Reverting fa7e7016 and letting things work like before.
What do you think would be the best solution given the use case of this feature?
