7 GObject signals can be used to notify applications of events specific to
8 this object. Note, however, that the application needs to be aware of
9 signals and their meaning, so if you're looking for a generic way for
10 application-element interaction, signals are probably not what you're
11 looking for. In many cases, however, signals can be very useful. See the
12 [GObject documentation](http://library.gnome.org/devel/gobject/stable/)
13 for all internals about signals.
