tkinter - Expanding a Listbox inside a Notebook

tkinter - Expanding a Listbox inside a Notebook

As the title says, I'm trying to make a Listbox object occupy all space
that is inside a Notebook pane.
Here is a screenshot of what I have so far:

What I want to do is to expand the Listbox to occupy all the space that's
on the right. I know that if I say listbox['width'] = value to a high
enough value, the Notebook panes' titles will not bug this. However I am
looking for alternative ways to do this, either resorting to grid() (what
I'm using in this project) or pack().
