Answer 1

What you want to do is to make sure that the canvas always has enough columns to scroll one whole screen right or left. The first thing to do is start with that many columns. If you want each column to be 100 pixels, and you want the canvas itself to be 400 pixels, then you need a total of 1200 pixels worth of columns: 4 columns to the left, 4 visible columns, and 4 columns to the right.

Next, create a proxy for the scrollbar -- a custom command that gets called whenever the scrollbar is dragged. The first thing it should do is call the xview method of the canvas to do the actual scrolling. Then, once the canvas has been scrolled you need to calculate if you need to add any more columns to the right or the left to always maintain the buffer.

Once you've added any new columns to the right or left, you need to recompute the scrollregion of the canvas. When you do that, tkinter will automatically adjust the position and size of the scrollbar thumb.
