Oh no, it doesn't depend on coordinates, it depends on screen! I just figured out, that on my left screen I get the whole window, but when moving the test window to the right screen, the offscreen drawing starts to get cut and when totally on right screen (my main screen) it vanishs. Offscreen drawing was first step to save a jpeg screenshot and now I can see, how it changes. It's the same, when using Fl_Window(x, y, w, h). Is it a known problem, that offscreen drawing doesn't work for both screens of dual screen systems? I'm using Fedora 14, Kernel 2.6.35.14, GNOME 2.32.0 _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
