Would https://www.swharden.com/wp/2010-03-03-viewing-large-images-with-scrollbars-using-python-tk-and-pil/ help?The complex UI element called "Table" that is created and handled within the exe does not support a horizontal scroll-bar, there is not much that can be customized about it within python really.
I am playing with the idea of creating a python class to be used to easily create tables that are made up of many small and simple UI elements without having to write lot's of code every time such a table is needed.
It would allow much of the table functionality to be held within python, but it's a big project so it will take time to make.
The build queue is a simple example of a table handled mostly within python.
