The JTabbedPane
class acts as a
combined container and layout manager. It implements
a conventional tab layout, which looks like Figure 13-2.
To add a tab to the layout, you do not use setLayout( )
. You simply create the JTabbedPane
and
call its addTab( )
method, passing in a
String
and a Component
. Example 13-1 is the code for our simple program.
Example 13-1. TabPaneDemo.java
import javax.swing.*; public class TabPaneDemo { protected JTabbedPane tabPane; public TabPaneDemo( ) { tabPane = new JTabbedPane( ); tabPane.add(new JLabel("One", JLabel.CENTER), "First"); tabPane.add(new JLabel("Two", JLabel.CENTER), "Second"); } public static void main(String[] a) { JFrame f = new JFrame("Tab Demo"); f.getContentPane().add(new TabPaneDemo( ).tabPane); f.setSize(120, 100); f.setVisible(true); } }
The third screen shot in Figure 13-2 shows the program with a MS-Windows look and feel, instead of the default Java look and feel. See Section 13.13 for how to change the look and feel of a Swing-based GUI application.
