I'm guessing your "UI" class is not actually derived from an FLTK widget. If so, that's the reason your handle() method isn't being called; FLTK doesn't know about it.
What you need is to make a class that /derives/ from an FLTK widget, and define your handle(int) method there, so that it /overrides/ fltk's own internal handle() method. Look at this example which shows just that: http://seriss.com/people/erco/fltk/#GLCursor This example derives a class "MyGlWindow" that derives from Fl_Gl_Window (in this case, but could just as easily be an Fl_Window) and defines a handle() method to override Fl_Gl_Window's own. Note that the handle() method calls Fl_Gl_Window::handle(e) to pass the event down to the derived class's handle() method, so that the underlying class gets a shot at processing the event too. Be sure yours does this, and preserves the return value for the handle() method, which is very important. In your case you can probably get what you want by leaving your existing UI class alone, but make a separate new class called MyGlutWindow, in a file called MyGlutWindow.H, eg: #include <FL/Fl_Window.H> // include the widget.. class MyGlutWindow : public Fl_Window { // ..that you derive from public: MyGlutWindow(int X,int Y,int W,int H,const char *L=0) : Fl_Window(X,Y,W,H,L) { } int handle(int e) { ..do your event handling here.. } }; Then in fluid, open the 'Properties' for the FLTK window you're trying to grab the events for, and under the C++ tab in the properties dialog, set the Class: to MyGlutWindow. Make sure your fluid file has a "#include <MyGlutWindow.H>", so that when fluid writes out the code, that include is always saved into the .cxx and/or .h file that fluid generates. This way fluid will use your derived window class instead of Fl_Window in your ui->make_window() call. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
