[Tkinter] Horizontal extension of widgets + frame size adapted to content

[deanhystad]

You don't need, nor even want, to use a canvas to scroll the tree. This will have the undesired effect of scrolling the column headers so they are not always visible. The tree widget knows how to work with a scroll bar. When you hook the scrollbar directly to the tree widget, moving the scrollbar only moves the column values. The headers remain visible at the top. I think this is what happens in menator's program.
