Dear Erik, I have a query here regarding how does a touch screen driver work? I have TS driver working but the calibration points seem to be not set properly. When I launch an qt application, the touch on "edit" dropdown button opens the "file" dropdown button. Any clink on any button of the application does not activate it but rather is activated when I click bit right to the button (off it). How do I set these calibration points & what is their importance? Thanks for ur previous support. I think u can help me in this regards too.
