FLTK Closing window

Question

I am using FLTK. I have a window with a variety of buttons the user can click to perform some action. In my int main() i have a switch statement to handle all of these. When the user clicks exit the switch statement is setup like so:

case Exit_program:
    cout << "save files and exit\n";
    do_save_exit(sw);

This goes to the do_save_exit function that creates a exit confirmation window with two buttons yes (exit) and no (don't exit). I got the yes button to work, exits the program, but the no button mean i should just hide the confirmation window. This is the follow functions:

void yes(Address addr, Address)
{
    exit(0);
}
void no(Address addr, Address)
{

}
void do_save_exit(Window& w)
{
    Window quit(Point(w.x()+100, w.y()+100), 250, 55, "Exit confirmation");
    Text conf(Point(15,15),"Do you really want to save and exit?");
    Button yes(Point(60, 20),35,30,"Yes",yes);
    Button no(Point(140, 20),35,30,"No",no);
    quit.attach(conf);
    quit.attach(yes);
    quit.attach(no);
    wait_for_main_window_click();
}

The problem is, when i click the no button it goes to void no, but I can't go anywhere from there. I just want to do quit.hide() but the no function doesn't have sight of the quit window (out of scope). How should I proceed? Thank you

P.S: I have thought about using a pointer to the quit window and then using the pointer to quit the window in the no function but am not sure how to do that exactly.

You probably need to look at using a modal (i.e., dialog) window. Look at <FL/fl_ask.h>

if (fl_ask("Do you really want to save and exit?"))
    save_and_exit();

The header also has functions for the popup's font, title, etc.
