: It should be easy to convert CreateRoundRectRgn to : a GrRoundRect function, but I'm not familiar with : Win32 API, and it seems that RECT in CreateRoundRectRgn : is not the same with GR_RECT. Could someone tell me : which structures and functions should be replaced?
This code may be a bit tricky, ultimately you will be rewriting it completely to use GrLine and GrDrawPoint calls to draw a rounded rectangle. The example you have uses region-unions, and none of that will work for drawing your rounded rectangle. To draw a rounded rectangle, each corner is drawn as one quarter of a circle, connected to the top, bottom and side lines. Perhaps you should just use the GrArc and GrLine routines after drawing a rounded rectangle on graph paper. For the arc radius, you can use the code in CreateRoundRectRgn that sets the left and right rectangle values. As another thought, I think FLTK supports rounded rectangles, you might look at that code and convert it to nano-X API.
