Qt 5.10.1 EGLFS libinput Touchscreen rotation
I try to do my first development on Rapsberri PI 3 and Qt.
I use Qt 5.10.1 with cross compilation for Raspberry 3
I have a 7" LCD with USB touchscreen rotate a 90°.
I found the solution to rotate the screen with config.txt adding :
and the touchscreen is rotated with adding call a batch script in
the script is :
xinput set-prop 'FocalTech Lab FTxxxx MultiTouch' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
So the touchscreen is working in startx
My problem is with programs in Qt using EGLFS and libinput. I can not rotate my touchscreen.
I read a lot a post talking about wayland, tslib, ts_calibrate, evdev.... But I think it is for old development.
I am pretty sure there is a simple solution for nowadays.
