I am writing a Python program in TKinter on Ubuntu to import and print the name of files from particular folder in Text widget. It is just adding filenames to the previous filnames in the Text widget, but I want to clear it first, then add a fresh list of filenames. But I am struggling to clear the Text widget's previous list of filenames. Can someone please explain how to clear a Text widget?

How can I mark a portion of a tkinter text widget as readonly? That is, I want to be able to allow editing only in certain parts of the widget. For example, I want to allow editing only after a prompt but not before, to simulate a console. The most bullet-proof solution is to intercept the low-level insert and delete commands, and put logic in there to prevent insertions and deletions based on some sort of criteria. For example, you could disallow edits within any range of text that has the tag "readonly". Here's an example of this technique. It takes advantage of the fact that all insertions

Every time a character is entered into a Text widget, I want to get the contents of that widget and subtract its length from a certain number (basically a "you have x characters left" deal). But the StringVar() is always one event behind. This is, from what I gather, because the event is processed before the character is entered into the Text widget. This means that if I have 3 characters in the field and I enter a 4th, the StringVar is updated but is still 3 characters long, then it updates to 4 when I enter a 5th character. Is there a way to keep the two in line? Here's some code. I removed
