I enable saving after a line is modified but I have 5 lines that can be
modified, that is originally why I did the isModified check. I suppose I
don't really need to save individuals values. I will switch to saving the
whole record.

Thanks for clearing it up what it was doing for me.

The completer calls setText(), which will always reset the modification state to \
False.<br> <br>
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.<br> <br>
But it&#39;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?<span class="HOEnZb"><font color="#888888"><br> <br>
