Qt 4.8.6 touch is not working
Need your help to understand qt touch process
My events are occurring in cat /dev/input/dev whenever I touch on screen
But when I run ts_calibrate it is not recognise my touch on screen also I have exported required environment variables still it is same
Can one help with this, thank you in advance....
If ts-calibrate does not recognize it as touch screen, it's possible that your device is seen as a mouse.

Thank you for replying @SGaist ,
How to check if my device is seen as mouse?
Coz in ts_calibrate I tried to click points using mouse but none of them get clicked...
then how to change to recognise as touch only?
That's something you should first check with the screen model you are using.
Not getting your point @SGaist
I am using goodix gt911 touchpad driver which recognises my touch on evetest
My point is: at no point did you mention what device you were using nor how it was supposed to be recognized by your system as a touch screen.
You just added now that it was recognized by evdev.
What if you disable evdev ?
By the way, are you locked to that old version of Qt ?
It has reached end of life a long time ago and you are not even using the latest of the Qt 4 series.
Ohh sorry, I am using friendlyarm arm linux based device
And that os using qt 4 only that's why we are stuck at qt version 4
And event are occurring on evdev as well as on cat I put device for touch meaning at kernel level it is working fine
But at user level it not recognise at all in qt app and in ts_calibrate

Hi @SGaist ,
Somehow I am able to resolve touch issue I am able to touch on my app now only issue is touch is inverted like when I move touch at right pointer move towards left......

There's the invert module explained in tslib's readme.
