Am I right that the only kind of non-rectangular clipping available in FLTK is FL:Window's set_shape() method?
Well, I guess that somewhat depends on what you're trying to achieve (and possibly on what you mean by rectangular too!)
For clipping within a window it may be possible to composite a series of overlapping rectangles to produce more complex outlines, for example (though not exactly smoothed curves!)
Also, many surfaces will allow you to define a stencil to draw through, which will clip to an arbitrary shape.
What is it that you are trying to achieve?
And, just to tie up with Manolo's comment, the approaches I suggest don't really have any "direct" support via fltk API, so will need some surface-specific coding, be that X11, Win32, Quartz, GL, etc... -- IanFrom my Fairphone FP3
