How do I scroll a JTable as the selection cursor moves out-of-view?

Question

If a row is selected in a JTable, and the user navigates up and down using arrow keys, as the selection moves out of view, the table automatically scrolls. In my app, I am programmatically selecting rows, but if the selection is out of view, the table does not scroll. does anyone know how to achieve this? I know I could examine the position of the selected row etc. and scroll the view myself, but this seems clunky. Ideally, I would fire off KeyEvents to get the behaviour for free, but I can't see where to fire them to

I know I could examine the position of the selected row etc. and scroll the view myselfWhy? Thats what the methods where designed for (assuming you are talking about the scrollRectToVisible(...) method).
Ideally, I would fire off KeyEvents to get the behaviour for free,That seems clunky to me.
When you use KeyEvents its a cause / effect relationship. That is first you use a KeyEvent to change selection. Then then if the table is at the bottom it scroll one row. So in you program if you on on row 5 and you want to select row 30, you would need to invoke 25 KeyEvents. Seems pointless to me unless you have special logice that processes every row as it gets selected.
If you want to persue this route then you can just invoke the default actions for the up/ down/ left/ right keys. This posting should give you an idea of how to do this:
