JTabbedPane

JTabbedPane is a component in the Java Swing library that provides a tabbed pane for organizing multiple components within a single window. Each tab displays a title and optional icon, and selecting a tab shows its associated component while hiding the others.

Tabs can be placed at the top, bottom, left, or right of the pane. When many tabs are present, the tab area can be configured to scroll or to wrap, depending on the layout policy. Each tab can have a tooltip, and individual tabs can be enabled or disabled.

JTabbedPane supports programmatic control of the currently visible tab, including adding and removing tabs, changing titles or icons, and listening for selection changes via ChangeListener. It also supports mnemonics for quick keyboard access to particular tabs.

Usage typically involves creating a JTabbedPane, creating a component for each tab, and calling addTab or insertTab with a title and optional icon. The pane is rendered by a pluggable UI delegate and managed by a model that tracks tabs and the selected index.

JTabbedPane is a standard Swing component available in javax.swing. It is designed to be used in cross-platform Java desktop applications and integrates with Swing’s look-and-feel, accessibility features, and event model.
