Use of touch screen

[reidarT]

Do I need to do anything in my application if I want to use a touch screen
instead of keyboard/mouse,
or is everything controlled by the screen drivers?

The touch screen drivers should control it. I have used both ELO and 3M
drivers and they both act the same. Just make sure your buttons take into
account fat fingers.

I have done this for my restaurant management program and it requires no
extra programming since the mouse events "Click" and "DoubleClidk" are
triggered by the touch screen. Also, you can implement Drag and Drop thru
the mouse down, move events and mouse up. However, some events such as mouse
move won't trigger unless the screen is pressed. Also, the mousehover event
won't work.

The main problem that I had was that the buttons have to be quite large
since the perspective of the user depends a lot on the height of the screen.
Also, you need to allow a button for the user to calibrate the touch screen
since it needs calibration almost weekly.
