The completer calls setText(), which will always reset the modification 
state to False.

You could disable the save button by default, and then connect the 
textChanged signal of all the line-edits to a handler which re-enables 
the save button as appropriate.

But it's also worth asking whether you *really* need to check whether 
each individual value has changed. Why not just save them all whenever 
the user chooses to save?
