Question:
I want to put a JTabbedPane on a tab of another JTabbedPane for using it as a chapter with different sections below it. How can I do this?
Answer:
You can add a JTabbedPane to a tab of another JTabbedPane in the same way you would add any other component to a JTabbedPane. JTabbedPaneoffers several add and addTab methods that allow different levels of flexibility when adding components. Some of the methods allow you to specify specific layout constraints or add components to a specific tab. The easiest way to get started withJTabbedPane is by using add(String title, Component component). This method will add a new tab with the specified title and containing the indicated component. To add a JTabbedPane instance, just use it as the component parameter. User interface design is not my forte, but I have found it easier to navigate documentation by using a tree control on the side, allowing me to view the entire outline. Embedding a JTabbedPane inside of another JTabbedPane may not be the most effective approach. Nonetheless, this example demonstrates how to do it:
import java.awt.*;import java.awt.event.*;import javax.swing.*;public class TabbedPaneDemo extends JFrame { JTabbedPane _parentTab, _childTab; public TabbedPaneDemo() { _parentTab = new JTabbedPane(); _childTab = new JTabbedPane(); _childTab.add("Section 1", new JLabel("in a galaxy")); _childTab.add("Section 2", new JLabel("far, far away ...")); _parentTab.add("Chapter 1", new JLabel("A long time ago")); _parentTab.add("Chapter 2", _childTab); getContentPane().add(_parentTab, BorderLayout.CENTER); } public static void main(String[] args) { Frame frame; WindowListener exitListener; exitListener = new WindowAdapter() { public void windowClosing(WindowEvent e) { Window window = e.getWindow(); window.setVisible(false); window.dispose(); System.exit(0); } }; frame = new TabbedPaneDemo(); frame.addWindowListener(exitListener); frame.setSize(400, 400); frame.setVisible(true); }}
