JTABBEDPANE

Java Swing Tutorial Explaining the JTabbedPane Component. A JTabbedPane contains a tab that can have a tool tip and a mnemonic, and it can display both text and an image.

The shape of a tab and the way in which the selected tab is displayed varies by Look and Feel.

Other JTabbedPane Examples

A JTabbedPane component provides quick access to the mulitiple JPanels using the same space and Window. Consider the following example, which shows the use of JTabbedPane to group information about an end-user.

        public static void main(String args[])
        {
                JTabbedPaneDemo2 tdemo=new JTabbedPaneDemo2();
                tdemo.setSize(300,350);
                tdemo.setVisible(true);                
        }

The above listing uses JTabbedPane to group together the Personal Information, Education Qualification and Areas of Interest of an individual.
