How do I force these ttk apps to resize when I resize the window?
<p>I have comments in a number of places where I've tried to use the columnconfigure or rowconfigure methods to cause the windows to resize, but none of it seems to be working. I can also take out mainloop() and my program runs exactly the same. This leads me to believe I'm perhaps not calling/using mainloop correctly. The methods are mostly just for organization, and I know they're not reusable methods right now. I was planning on maybe fixing that at some point, but that's not the purpose of this post. </p>
