public class JTabbedPane

extends JComponent

implements Serializable, Accessible, SwingConstants

A component that lets the user switch between a group of components by clicking on a tab with a given title and/or icon. For examples and information on using tabbed panes see How to Use Tabbed Panes, a section in The Java Tutorial.

Tabs/components are added to a TabbedPane object by using the addTab and insertTab methods. A tab is represented by an index corresponding to the position it was added in, where the first tab has an index equal to 0 and the last tab has an index equal to the tab count minus 1.

The TabbedPane uses a SingleSelectionModel to represent the set of tab indices and the currently selected index. If the tab count is greater than 0, then there will always be a selected index, which by default will be initialized to the first tab. If the tab count is 0, then the selected index will be -1.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JTabbedPane key assignments.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.
