Hi all,
I have an image and want to enable tracking the mouse as you move around the screen or image. When I move the mouse on the image, the portion of the mouse pointer on image has to be displayed on other window.

I want some idea about how I can do it using qt3.3.x

Some more info-->
I have created a QMainwindow, a widget where the image is displayed, The mainwindow is the parent of widget. The zooming option on mouseWheel event is finished and I'm able to zoom the image.

Please follow this link to get an idea about what I want
