Hi everyone,

I have a Gui created from using Qt where it has widgets that creates 
locators (populated as part of a list item in QListWidget) and interacts 
with some of its attributes (eg. the TranslateXYZ + Local PositionXYZ)

In maya context, you will be able to perform n times of undo. But my 
question here is how can I make undo to happen within the Gui?
Currently, if I have made changes in (assuming by default the line edit 
starts with 0):

   - Set 10 in the translate x line edit
   - Set 5 in the translate y line edit

If I tried to press 'Ctrl+Z' where the translate y line edit is in focus, 
it is able to change the value from 5 to 0.
However if I go to the translate x line edit, nothing happens and the value 
still stuck at value of 10.

Or if I have made a button that says "Key Selected", while it does keys the 
attribute, however when using Undo, I have to hit Ctrl+Z multiple just so 
to 'remove' the key that I have set.

Is there a better way in which I can try adopting that allows me to do undo 
more efficiently?
