Yes. I did this a while back, but would need to find an archive to 
provide you with exact code.

Connect to the GtkCellRenderer "editing-started" signal. In that 
callback, you will have an GtkEntry (GtkCellEditable) object. Connect to 
the Entry's "changed" signal and keep a permanent string around with the 
text the user is typing. Also preserve the path and column being edited 
(obtained with "editing-started").

Also connect to GtkCellRenderer "editing-canceled" signal. In this 
callback, use the path, column, and text you retained from 
"editing-started", and update the ListStore.
