How to check the changes/Edit done on the form onStackWidget

Hi All,

I have Form on Stacked Widget now end user can edits the form, I need to prompt a message box only in case the form is edited.

How we can check this scenario in QT.

Thanks in Advance,

What do you mean with "prompt a mesagge box only in case the form is edited"?
Do you mean that someone can enter new data and after pressing a button (for example) a message box is shown?

If so, compare current values against previous values.
