Finally, the following code worked. Can you tell me why?
int main(int argc, char **argv)
{
// Fl_Group::current(NULL);
// Fl_Window *w = new Fl_Window(0,0,0,0);
Fl_Button *button1 = new Fl_Button(2,2,80,40,"Hello");
Fl_Group *flow_panel = new Fl_Group(2,2,100,100);
Fl_Group::current(flow_panel);
flow_panel->begin();
flow_panel->add(button1);
flow_panel->end();
Fl_Window *window = new Fl_Window(2,2,300,300);
Fl_Group::current(window);
window->begin();
window->add(flow_panel);
window->end();
window->show();
//flow_panel->show();
//button1->show();
Fl::run();
return 0;
}
Thanks & regards, Asif
