I would like to pop up a dialog from one of the tables on my screen. I am having issues. I am not sure if I set up the editor properly. I have seen code where dialogs are created outside of the custom editor's code and inside, which is proper? I know i have to use a button and encapsulate the button with the editor, should i show the dialog when the button is pushed, or when the editor begins editing? Where can I find examples/information

getContentPane().add(scroller, "North" );
JPanel jpnl1 = new JPanel();
back = new JButton("Back to Do a New Search");
jpnl1.add(Box.createRigidArea(new Dimension(5,5)));
getContentPane().add(jpnl1, "South");

JPanel jpnl2 = new JPanel();
JLabel displayheadline = new JLabel("Click a airline that you
prefer to make a booking");
