Fickering on JTable / Double Buffering

[Jason]

I have an applet which basically consists of a big JTable.

However, every time just a single cell in the table is updated, the whole
table flickers when repaint is called.

How can I get rid of the flicker. I have tried using double buffering, but
that doesn't work or I am not doing it right. Is double buffering the way to
do and if so, how do you achieve this with a JTable

Thanks

J

Swing components are double buffered by default. If you have code in there
that is trying to double buffer that may itself be causing problems. You
also shouldn't be calling repaint. You should be firing a cellUpdated call.
That way the renderer only needs to repaint the appropriate cells, and not
the complete screen.

Have you looked at the Sun tutorial on using JTables at
