Oh yes, I remember that. Yes, it was sluggish, if I recall your sample code correctly, but it did more or less work. > Now the interesting news: there are also many components with > rectilinear shapes (like L-shape, T-shape and many more). > > The easiest way - for me - would be the possibility of > widgets not only x,y,w,h but with a polygonal boundary. This > would be a cool feature :-). Irregular widgets are tricky. One thought though, is this a sort of "tetris-like" scene, where all the polygons could be built from simpler rectilinear widgets? If so, maybe you can derive a "Fl_Lego" from Fl_Box (or FL_something, anyway) then use that to make your shapes up. That could then be dropped onto your surface like the current boxes, and pop up your tooltips etc. In my head (and I have not actually tried to write any code for this) the "Fl_Lego" would contain a list of Fl_Boxes that comprise the full shape, and all the boxes would have the same colour, tooltip, etc. Well, maybe, I don't know...
