I'm using Tkinter in Python, and trying to create code to run when a text box's value is changed. All the code I find online uses a mysterious tk member of Tkinter widgets, and I can't find any documentation on it! I found it's of type tkapp, but there's no documentation on that either.
Where can I find a decent resource which explains to me the workings of this mysterious thing? (Even better, where can I just find documentation on Tkinter? All I can find are tutorials).
tkapp is the highest "master". If you make a widget on the root window, tkapp is the master of that.
What is Tkinter's tkapp?
