Touchscreen no work
-
Hello Qt people,
I try run my projet on RPI, I had follow this tutorial for cross compilation,
https://visualgdb.com/tutorials/raspberry/qt/embedded/Now I can use qmake and make, and compile for my RPI, launch the app directly with console without desktop environnement,
I can start application (simple test app with one button and messagebox), if I use mouse it work.
But I need use touchscreen (USB), and this one doing nothing.
Can you give to me way for fix my problem ? I had try tslib, I can calibrate touchscreen with ts_calibrate and some parameter, but when I use command ./myapp -plugin tslib, app return warning "qt tslib couldn't load module input".
NB: In this tutorial in ./configure I don't put qt-mouse-tslib parameter.
Have nice day

What does this mean? Does your touchscreen not work at all? Or you do not get the touch events?

Hello jsulm,
The touchscreen not work at all, I had some result with use environnement variable QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event0
But the event "clicked()" no work, only "pressed()"
If I touch one button with clicked event, it's visual pressed but no exec his event.
