Loosing my JTable after I print
I am working on an application in which I query a database, then display the information in a JTable. If the user desires, they can hit the PRINT button which will print the table for them.
The problem I am having is that after the user hits OK on the print dialog box, the JTable they are working with disappears! It print fine, but for some reason I cannot go back in and re-create or edit the table without destroying the whole object and starting over. Any suggestions?
