Hey! I am trying to implement the undo and redo facility in pyqt. I have gone through some sites and was wondering whether iyou always need to create subclasses and their definitions for the undo/redo action. My program currently has a single window in which the user enters information which is used to update a text file as soon as the user leaves the field- so i essentially need to undo the text in that field as well as the file. I am puzzled as to how to approach this. Any help will be much appreciated!
