Selectively trapping keypresses

["Jeffrey Ratcliffe" <jeffrey ratcliffe gmail com>]

How do I check whether a Gtk2::Ex::Simple::List is being edited (when
selectively trapping keypresses)?

I want to

a. When the user presses enter, save the new data to a file
b. Whilst the user is entering data, suggest values (text)

Are there edited or insert-text signals? I can't find anything.

I'm not sure of the best way to proceed, and would be grateful for any help.

Regards

Jeff
