Um, I may be missing something important, but why have you created a new button
inside your derived button class?
In general, that is not needed...
Here's a way to do this; perhaps this is what you meant?
---------
// fltk-config --compile button-demo.cxx
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Button.H>
class newButton : public Fl_Button
{
public:
newButton(int x, int y, int w, int h, const char * l = 0):Fl_Button(x, y, w,
h, l)
{
box(FL_GTK_ROUND_UP_BOX);
color((Fl_Color)24);
selection_color((Fl_Color)24);
labelcolor(FL_WHITE);
labelfont(1);
}
};
static Fl_Double_Window *main_win = (Fl_Double_Window *)0;
static void cb_Quit(Fl_Button*, void*) {
if(main_win) main_win->hide();
}
int main(int argc, char **argv) {
main_win = new Fl_Double_Window(100, 100, 439, 321, "Main win");
main_win->begin();
newButton* myButton = new newButton(345, 265, 80, 35, "Quit");
myButton->callback((Fl_Callback*)cb_Quit);
main_win->end();
main_win->show(argc, argv);
return Fl::run();
} // main
/* end of file */
