gtkmmm-2.4 TreeView and Tab key for saving data to Model



Hi list,

I'm a new user of gtkmm2-4 and I've already tried all the examples in
the documentation. I've found some old emails in the list that explain
how to change cursor position in a ListStore via tab-key but none
explain how to save the edited cells after pressing tab. From the
documentation I've understood that using append_column_editable()
instead append_column should be enough but only if U press Enter key. I
would like to have the same behavior, such as saving inserted
information, but using the TAB. Is there an easy way to do that? 

Thank you.

g.
