Hi, I am trying to modify the fl_dial class to look something like this: http://soundsandgear.com/wp-content/uploads/2009/07/massive.jpg
I have created the images i need, but i can't find a way to show them "nicely". Using fltk image classes I have some problems: 1) when i scale them they look bad. 2) i can't rotate them 3) fltk doesn't seem to handle transparency correctly (with .xpm alpha works, but it's only a 1 bit alpha) 4) it crashes if i try to load a too big png (eg. 500*500 px) I tried doing some test with opengl (as the documentation says it's possible to use opengl to draw inside a widget) but the opengl image just flashes and disappears suddenly. Is it actually possible to draw a widget with openGL? Can someone give me a small example? I also tried using another library for image processing (cImg), but they use a different image representation, so i have to convert it pixel by pixel and it's too slow. Tl;dr: HOW DO I GO ABOUT MAKING A COOL LOOKING WIDGET? (antialiased, scales properly (interpolation)) I would also like to know, if my widget "changes shape" is there a way in his draw() method to first redraw the background and then draw the widget itself? otherwise it would leave a 'trail'... please someone help me! _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
