I need to load a text file with 5,000 - 10,000 lines of text into a grid with 16 controls per row (3 text fields and 13 radio buttons), then allow the user to scroll through the data smoothly. Currently I create a grid layout and load all the rows of data at once. This works for small files (< 1000 rows), but after that the load times for creating the grid increase dramatically. (Last time it took 10 minutes to load, and scrolling was unendurably slow.)

Clearly, creating 100,000+ controls is not a scalable solution, so I will have to create a smaller grid and page through the data, swapping the bound variables constantly. And I will need to play with the scrollbar, because the bottom of the loaded data is not necessarily the bottom of all the data.

Does anyone have any Tk examples that do this? I have only used the Scrolled method to make scrollbars, and I doubt that it can handle this situation (unless you know otherwise!)
