Gtk+ Signal question

[Michael Lausch <mla gams co at>]

Suppose i have a class which emits two signals. `error' and
`warning'. I want to have a defautl action for this signals, if the
user didn't connect any actions to the signal. The default action
should not be executed, if the user wants to handle the signals. If no 
actions are connected to the signals, the default action shoudl be
executed.

How can this be done?
