Shows a widget. If the widget is an unmapped toplevel widget (i.e. a GtkWindow that has not yet been shown), enter the main loop and wait for the window to actually be mapped. This is equivilent to calling show immediately followed by gtk::main() .

Note: Once the main loop has begun your application will be able to recveive user events. Make sure that show_now() is the method you want to call before using it.
