/** Create popup windows.
 *
 * Dialog boxes are a convenient way to prompt the user for a small amount
 * of input, eg. to display a message, ask a question, or anything else that
 * does not require extensive effort on the user's part.
 *
 * gtkmm treats a dialog as a window split vertically. The top section is a
 * Gtk::VBox, and is where widgets such as a Gtk::Label or a Gtk::Entry should be
 * packed. The bottom area is known as the action_area. This is generally
 * used for packing buttons into the dialog which may perform functions such
 * as cancel, ok, or apply. The two areas are separated by a Gtk::HSeparator.
 *
 * The dialog can be 'modal' (that is, one which freezes the rest of the
 * application from user input) - this can be specified in the Gtk::Dialog
 * constructor.
 *
 * When adding buttons using add_button(), clicking the button will emit
 * signal_response() with a "response id" you specified. You are encouraged
 * to use the Gtk::ResponseType enum. If a dialog receives a delete event,
 * the "response" signal will be emitted with a response id of
 * Gtk::RESPONSE_NONE.
 *
 * If you want to block waiting for a dialog to return before returning control
 * flow to your code, you can call run(). This function enters a
 * recursive main loop and waits for the user to respond to the dialog, returning
 * the response ID corresponding to the button the user clicked.
