I've got a wacom pen with a button. How can I trigger scrolling when moving the pen with the button pressed?
According to xev
, below, the triggering events are MotionNotify with state 0x200.
If this isn't done trivially, an idea I have is to build a service to read these events from somewhere and transform them into other events. This way, I can define gestures, as well. With this approach:
- Where can I read them?
- How can I write events back?
- Are there libraries to detect gestures?
