Undo and redo features in a Tkinter Text widget?

Question

I need to make both a Control + Z and Shift + Control + Z function in a Tkinter Text widget, so that one may undo and redo things.

Does anyone have an idea on how to do it?

Answer 1

The tkinter Text widget supports undo and redo operations using a stack

At the following link you can find more information:

http://www.tkdocs.com/tutorial/text.html#more

Otherwise you could look at the tkinter or Tk docs for the Text widget and how to create a binding to some keys. The tkinter Text widget function you need is edit_undo.

Answer 2

The Tkinter Text widget already supports undo with Control + Z and redo with Shift + Control + Z, but you have to enable them on the widget with undo=True. You might also want to use autoseparators=True and maxundo=-1. See this link https://www.tcl.tk/man/tcl8.5/TkCmd/text.htm#M65.
