JTable doesn't repaint
Henri Benoit
I have a JTable. At the beginning the model is empty. Then I feed data
in the model but nothing happens. I just wrote a few
System.out.println(<name of the function>) at the beginning of all the
functions. It says I set the data in the model (5 rows) and then
getRowCount is called 5 times and each time returns 5. But the display
isn't refreshed and getValueAt is never called. After setting the rows
in the model, I do call repaint() but it doesn't seem to do anything
(The five calls to getRowCount() are made after I call repaint()).
I got another table which works fine. I couldn't find any difference in
the code. The only difference I see is that the one which works is
contained in a JScrollPane in a JFrame and the one which doesn't work is
in a JScrollPane in a JPanel in a JTabbedPane.
Has anybody experienced the same problem and solved it ?
Thanx

refreshing by itself. To see changes instantly you need to call revalidate()
method on JTable and then repaint() after setting the data.

of the fire... methods it provides. When you've modified the model, call one
of them to get the table to redraw. They generate a TableModelEvent which is
sent to the table (it's a listener of the TableModel) and the tableChanged
method is called and this calculates just how much of the table needs to be
redrawn. If you just call invalidate() or repaint() you may end up drawing
much more of the table than you really need to, and this can slow things
significantly if your renderers are drawing something complex.
