touch events in linux using Qt

Question

I am trying to program touch events in linux using Qt. My touch screen works, however when I touch the screen I get mouse events rather than touch events. The mouse cursor moves to where I touch the screen. I don't know if it is a Qt problem or something that happens at the OS level.

I am using Qt 5.4.0 on Debian Jessie.

Since you did not share any source code, its hard to know what happens wrong on your side. Take a look at this documentation:

• Detailed Description of QTouchEvent Class
• Touch Input Examples

All that examples works well, and you need to test it on your side. If it will not work for you, it means that there are some problems on your side, otherwise, it mean that you forgot something in your application (like Qt::WA_AcceptTouchEvents attribute set, or not set to true the acceptTouchEvents attribute at graphics items...).
