I haave written a programm, in which you can click buttons, and a text will appear. Now, I have to know, if MousePressed() works on a touchscreen monitor, that means you dont click the mouse, but you tap the screen.

Yes, it should work the same. I use Processing‘s IOS version, and mousePressed detects Touch input, so it should work the same for you.

I have a touchscreen laptop. If you want, I can test some code for you.

It works fine on my Lenovo Yoga. If I keep my finger on the screen and move over the buttons they get a red outline (hover effect), and when I release my finger it counts as a click.
Keep in mind that once I’ve clicked somewhere on the screen, the mouse cursor is still there but it’s turned invisble by Windows.This means that once I’ve pressed the back button, the button in the left corner is hovered since my invisible cursor is still placed there. The moment I touch the screen elsewhere the red hover effect vanishes.
If you need anything else tested just let me know 🙂

could you check already what hardware that would be? you have to run with?
> a monitor with
- a HDMI input
- USB output ( from like capacitive touch screen )

it is like a normal screen, but it has touch. Also the input is VGA

you can touch any monitor…
but if it has a touch screen it still have to give
that TOUCH EVENT back to the computer ( emulating a mouse ? THATs the question )
( and can not do by a VGA cable i think )

i not understand what is the problem to ask the people what told you
about that you have to use that equipment.
( or do a pre test on it )
