I am using Qwt 5.0.1 and Qt 3.3.5. I want to subclass my own PlotCurve from QwtPlotCurve.
The derived PlotCurve may looks like a circle with a filled color. I give it left, right, top, bottom and center point data(or only a radius and a center point data) and also a specified filled color. The PlotCurve should be shown as a filled circle based on these data by .
Could someone tell me the basic method to do it ? Some code examples will be better.
Thanks a lot.
Best regards
