Invert Mouse Position

I have a QT GUI where i needed to rotate when launching the Application
due to mechanical position of the LCD.

I use this on launching the App.
./myApp -qws -display transformed:rot180:1

It flips the GUI correctly. However the mouse is reversed.
- If i move the mouse to left it move right on the GUI.
- If i move the mouse to right it move left on the GUI.
- If i move the mouse to up it move down on the GUI.
- If i move the mouse to down it move up on the GUI.

How do invert the mouse movement?


Thanks
