You will have to register changeListener with your JTabbedPane.
eg.
if you have a JTabbedPane _tabbedPane, after instantiating, you add a changeListener to _tabbedPane...
_tabbedPane.addChangeListner(new YourChangeListener());
-------
now, this class called YourChangeListener, will get notifications if a diffrent tab is selected.
the definition of the class will look like this:
public class YourChangeListener implements ChangeListener{
//you will also need a method called stateChanged
public void stateChanged(ChangeEvent changeEvent) {
JTabbedPane sourceTabbedPane = (JTabbedPane)changeEvent.getSource();
int index = sourceTabbedPane.getSelectedIndex();
System.err.println("Currently selected tab no. is : "+index);
}
}
