User defined rotations and scales with the mouse?

[qlands]

Hi,

Do anyone knows of an example for implementing user defined rotations and scales using the mouse and using QTransform or QMatrix4x4? For example having a polygon on a 2D canvas, to allow the user to scale and rotate the box with the mouse.

Thanks,
Carlos
