Hi David, take a look at the source for gtkadjustment, you can copy out
the bits you need.

You need to:

- make a new class, inheriting from GtkData
- have a member for your signal
- haev a static array of signal ids in your implementation
- build the signal in _class_init with gtk_signal_new()
- attach the signal to your class with gtk_object_class_add_signals()
- provide a function which emits your signal from an instance
