Listener for a JTabbedPane

Question

HI all,
I am trying to update a String on a "summary tab sheet" (in a JTabbedPane) when the tab is selected. When I look in the API, I notice that it has a ChangeEvent associated with it, but I am not quite sure when it fires. I was assuming that it was when any of the tabs were clicked on. The following code compiles and runs, but doesn't execute the code in the stateChanged method that I have defined here. "vehiclePane" is the name of my JTabbedPane. I had the same code (the code in the stateChanged method) in an ActionListener (actionPerformed method) which fired off of a button on the summaryPanel, and it generated the results I wanted into the JTextArea on the summaryPanel. But my assignment calls out to have the String updated when the tab is clicked. I would appreciate any advice!
vehiclePane.addChangeListener(new ChangeListener()
public void stateChanged(ChangeEvent e)
String carOptions = getOptions(myOptions);
String summaryStatement = ("The Type of Auto is a : " + getType(type)+ "\n\n" +
carOptions + "\n\nThe Interior Color is: " + color.getIntColor() +
"\n\nThe Exterior Color is: " + color.getExtColor() +
"\n\nThe Price of Your Vehicle is: $" + price.getNewPrice());
setTextArea(summaryStatement);
});

Swing related questions should be posted in the Swing forum.
-> I was assuming that it was when any of the tabs were clicked on.
You assume correctly. If it doesn't work then you are doing something wrong. Hence the need for a SSCCE.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.
