Python Tkinter, problem with alignment of buttons in Notebook widget

Question

I have a problem with the Notebook-widget of Python's Tkinter-module when aligning buttons.

I don't understand how to achieve in the attached code, that in the 'text'-tab the two buttons 'previous' and 'next' stick to the lower border of the root-window, independent of the length of the text in the Message-widget. The two buttons shall only be present in the 'text' tab, not in the other two tabs.

I want to display different texts of different lengths and I want the buttons be always positioned at the lower border of the window.

Could anybody explain what I have to change in the code, please?

Answer 1

I configured 'tab1' with 'rowconfigure' and it worked. It is indeed the main frame of the tab1...
Hope it helps
