// "$Id$"
//
// Standard dialog test program for the Fast Light Tool Kit (FLTK).
//
// Demonstrates how to use readqueue to see if a button has been
// pushed, and to see if a window has been closed, thus avoiding
// the need to define callbacks.
//
// This also demonstrates how to trap attempts by the user to
// close the last window by overriding Fl::exit
