How the manual scroll should work?
If through the WAIT(-1) command, i should receive a list like this: {type, [x,y], [dx,dy]}
where:
type should be the type of touch event
[x,y] should be the initial position and
[dx,dy] should be the delta from the last mouse down.
Does this mean that i need to track a MOUSE DOWN (type 0) and then a STRETCH (type 5)?
it is not clear to me the logic of how it works,
thanks for any clarification,
Giancarlo
