Brian,
Indeed glrect is gl2, I meant you can use gl2 cmd to draw on a isigraph surface
and then save the result into a bmp file. Then display the bmp on an owner-draw
button so that you do need to worry paint event.
For your context, I agree with Oleg that it should be done on one isigraph only,
One reason is that isigraph is never transparent even if glclear because there
will always a white background. Similar to J grid or treeview, visualise that
there is a large canvas and draw everything (bitmap, frame, rectangle, button,
line, checkbox, ...) by yourself.
