JTabbedPane In Java

Tab Indexing and Placement in JTabbedPane

An index is determined by the location or position in which the tab was added to represent the tabs.

Let's assume you added your first tab to comprehend this better. Then, according to fashion, your last tab added will have an index equal to "tab count minus 1" and your next tab will have an index equal to "0."

The Tabbed Pane classes employ a single selection model that represents both the "now selected index" (i.e., the selected tab's index) and "a group of tab indexes."

As you can see in the property tabbed pane of the window above, the tabs are default positioned at the TOP position. By using the setTabPlacement method, you can move this tab in any of the directions, such as LEFT, RIGHT, or BOTTOM.

Here, we go into further depth about an example of a JTabbedPane in Java:

We will attempt to add the tabbed window to our JFrame at this point. Javax.swing will be used. We will have the ability to add tabs to our frame thanks to the JTabbedPane package.

The example code below uses JTabbedPane to add tabs to our frame.

JTabbedPane Exampletab placement

import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTabbedPane;
public class JTP_Layout
{
JFrame frame;
JTP_Layout()
{
//Creating our JFrame
frame= newJFrame("Tabbed Pane Sample");
//Terminating process after exiting
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Adding TabbedPane Object
JTabbedPanetabbedPane = new JTabbedPane();
//Adding TabbedPane LayoutPolicy
tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
//TabPlacement
//tabbedPane.setTabPlacement(JTabbedPane.BOTTOM);
//Setting our componentobject
//JRadioButton r1=new JRadioButton("A) Tab Component A");
//r1.setBounds(30,30,100,90);
//Adding our First Panel Object
JPanel p1=new JPanel();
//Adding our component to the Panel
//p1.add(r1);
JPanel p2=new JPanel();
JPanel p3=new JPanel();
//Setting boundary values for the tabs
tabbedPane.setBounds(50,50,200,200);
//Naming 'One' asour First Pane
tabbedPane.add("One",p1);
tabbedPane.add("Two",p2);
tabbedPane.add("Three",p3);
//Setting Frame'sposition to the center
frame.add(tabbedPane, BorderLayout.CENTER);
//Setting FRame'sSize
frame.setSize(400, 150);
//Setting visibility asTrue
frame.setVisible(true);
}
public static void main(String args[])
{
new JTP_Layout();
}
}

The output of the aforementioned application is displayed in the window below.

In the example above, we added tabs to our JFrame and gave them various names, such as "One," "Two," etc. Using a straightforward code line like the one below, we can add multiple components under our various tabs.

To add radio buttons to panel One, also known as p1, we first constructed an object for the radio button, designated as r1.

And underneath our initial panel, where we added it, the "Radio Button" component will show up.
