Java Forum / GUI / January 2005JTabbePane
I have a JTabbedPane and have three JPanels forming the three tabs. I need to set the default button on one or other Panel depending which one is active / showing at the time. How do I do this ? I need to toggle the default buttons on the panels but I need to know which panel is currently showing. Do I detect the active panel using a listener on both Panel classes or can I detect something and set it in the JTabbedPanel ?? > I have a JTabbedPane and have three JPanels forming the three tabs.

The ChangeListener will get notified whenever the selected tab changes; the JTabbedPane itself will be the source of the ChangeEvent, and then you can call getSelectedComponent or getSelectedIndex to see what is currently showing.
