   4 // Standard dialog test program for the Fast Light Tool Kit (FLTK).
   5 //
   6 // Demonstrates how to use readqueue to see if a button has been
   7 // pushed, and to see if a window has been closed, thus avoiding
   8 // the need to define callbacks.
   9 //
  10 // This also demonstrates how to trap attempts by the user to
  11 // close the last window by overriding Fl::exit
