With the JTabbedPane class, you can have several components, such as panelsshare the same space. The user chooses which component to view by selecting the tab corresponding to the desired component.

If you want similar functionality without the tab interface, you can use a card layout instead of a tabbed pane. To create a tabbed pane, instantiate JTabbedPanecreate the components you wish it tutroial display, and then add the components to the tabbed pane using the addTab method.

Java JTabbedpane Class Example

The following picture introduces an application called TabbedPaneDemo that has a tabbed pane with four tabs. As the TabbedPaneDemo example shows, a tab can have a tool tip and a mnemonic, and it can display both text and an image.

The default tab placement is set to the TOP location, as shown above. The following code from TabbedPaneDemo. Note that no event-handling code is necessary. The JTabbedPane object takes care of mouse and keyboard events for you. As the previous code shows, the addTab method handles the bulk of the work in setting up a tab in a tabbed pane.

The addTab method has several forms, but they all use both a string title and the component to be displayed by the tab. Optionally, you can specify an icon and tool tip string. The text or icon or both can be null. Another way to create a tab is to use the insertTab method, which lets you specify the index of the tab you’re adding. Note that the addTab method does not allow index specification in this step.

To switch to a specific tab programmatically, use the setSelectedIndex or the setSelectedComponent methods. When building components to add to a tabbed pane, keep in mind that no matter which child of a tabbed pane is visible, each child gets the same amount of space in which to display itself. The preferred size of the tabbed pane is just big enough to display its tallest child at its preferred height, and its widest child at its preferred width.

Similarly, the minimum size of the tabbed pane depends on the biggest minimum width and height of all its children. In the TabbedPaneDemo example, the fourth panel has a preferred width and height that are larger than those of the other panels.

Thus, the preferred size of the tabbed pane is just big enough to display the fourth panel at its preferred size. If you do not understand how preferred size is used, please refer to How Layout Management Works. The TabComponentsDemo example introduces a tabbed pane whose tabs contain real components.

The following code from ButtonTabComponent. Note that event-handling code is necessary. Since each tab contains a real JButton object, you must attach an ActionListener to the close button. As the user clicks the button, the actionPerformed method determines the index of the tab it belongs to and removes the corresponding tab.
