/* This program displays a "pulsing" (or whatever it's called)
 * ProgressBar, adds a timeout function to keep it updated, shows how
 * to make a derived widget in conjunction with libglade, demonstrates
 * overloading a function for a signal instead of connecting a
 * separate function to the signal, and show using a glibmm timer.
 *
 * Note that most programs update progress bars during some kind of
 * function that doesn't return to the main event loop (unlike this
 * simple example).  In that case, you must manually tell gtk to
 * update widgets yourself by calling Gtk::MainContext::iteration.
 * (See example-3.cc for an example of doing this in a different
 * context).
