Tkinter Entry Widget Not Updating

I've searched everywhere on the web but unfortunately no where did I find an answer to this question: after setting a tkinter Entry() widget's textvariable to a textvariable. the

Solution 1:

A textvariable associated with an Entry should be a StringVar(). I don't se any such declaration in your code.

self.save_file_name = StringVar()

To set and get the value of a StringVar() you must use the set() or get() method, eg.

defsaveFileName(self):
    if(self.save_file_name.get() != ""):
        self.window.destroy()
        # etc, etc.

Also, don't create more than one instance of Tk() as in:

defaskForFilename(self):
    self.window = tk.Tk()

Use Toplevel() instead. Or even better: use the tkinter filedialogs.
