You got to watch the order in which things are updated and so forth in
your loop - for me this works better:
----------------->%---------------------------------
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
static void cb_close(Fl_Widget*, void*) {
Fl_Window *win = Fl::first_window();
while(win)
{
Fl_Window *tmp = win;
win = Fl::next_window(win);
tmp->hide();
}
}
int main(int argc, char **argv)
{
Fl_Double_Window *w1 = new Fl_Double_Window(500, 300, "Win 1");
w1->box(FL_FLAT_BOX);
w1->end();
w1->callback(cb_close);
Fl_Double_Window *w2 = new Fl_Double_Window(500, 300, "Win 2");
w2->box(FL_FLAT_BOX);
w2->end();
Fl_Double_Window *w3 = new Fl_Double_Window(500, 300, "Win 3");
w3->box(FL_FLAT_BOX);
w3->end();
w1->show(argc, argv);
w2->show();
w3->show();
return Fl::run();
}
/* end of file */
