I have a JTable in a JScrollPane.  The JTable may contain up to 100,000
items.

When I grab the scroll cursor and move it down, the table model's
getValueAt(rowIndex, columnIndex) method for every item in the entire range.

What I want is to only refresh the contents of the JTable when the user has
dropped the scroll cursor in it's new location, not during the entire drag
range.

Is there a simple way to tell JScrollPane to only refresh the view only
after the drag of the cursor is done?

Sam

There is no simple way that I am aware of.

Of course, it is possible to do, but you would probably have to
customize the UI delegate classes, which gets complicated.
