painting a compass

hi friends,

my present target is to create a compass or a 360* plane showing a polar coordiate on the plane .. can any one suggest me a good way to paint the object where i can have a control on coordinate systems or having experience on working similar object ...

thanks in advance ...

Qwt has a compass widget. QwtPolar offers a plot widget for polar coordinates.

and can we override the widget paint to our will ..?
bcz i tried QPlotter but without docs of Qwt i felt handbroken ...
