9.3. The abstract message utility functions
Gnome provides utility functions for relaying simple messages to the user and asking simple questions. The utility functions serve two purposes: first, they keep programmers from writing dozens of identical dialogs; second, they let the user choose whether messages should appear in dialogs or on the appbar. The main set of utility functions assume that your app uses the GnomeApp widget, and that one is visible at the time they're called. These functions have a dialog backend and an appbar backend. The dialog backend is exposed, so you can use it directly if you have no GnomeApp widget available. The GnomeApp functions do not assume you have an appbar available; you should use them even if your app has no appbar. In some cases it makes a difference (for example, dialog can be positioned relative to the GnomeApp).
