[Advanced-java] window refresh question

[Jesper Berglund]

Hi Alvin.

How does the application recieve data for the tables?
If it is on the event dispatch thread I can clearly see the swamping.
Try recieve the data on another thread and add it in you're tablemodel 
with  SwingUtilities.invokeLater().

Does the table show all the data available?
Make the operator search for the data that the operator is interested of 
and set a maximum value for the number of rows in the table.
In my experience the "search for data by scrolling the table up and 
down"-method with a large amount of table rows is inefficient and a 
waste of time.
