Have a look in
/etc/X11/xinit/xinitrc and see if there are any lines like this;
DISPLAY=:0 xinput --set-prop 'ADS7846 Touchscreen' 'Evdev Axes Swap' 1 DISPLAY=:0 xinput --set-prop 'ADS7846 Touchscreen' 'Evdev Axis Inversion' 1 1
If there are, delete them.
Then delete the calibration file and then reboot to run the calibration program again.

I am not familiar with Qt. However, in your code.. can you force it to display the output on a given framebuffer? If so.. use framebuffer /dev/fb1
