- public class JTabbedPane
- extends JComponent
- implements Serializable, Accessible, SwingConstants
A component which lets the user switch between a group of components by
clicking on a tab with a given title and/or icon.
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 indeces 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.
- See Also:
- SingleSelectionModel
See How to Use Tabbed Panes
in The Java Tutorial
for further documentation.
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 Swing1.0 applications. It will
not be possible to load serialized Swing1.0 objects with future releases
of Swing. The JDK1.2 release of Swing will be the compatibility
baseline for the serialized form of Swing objects.
