This is an example on how to create a new JSplitPane component for a Java Desktop Application.The JSplitPane is commonly used component because it lets you split your window horizontally or vertically in order to create a wide variety of GUI elements to suit your application’s needs.

In short in order to create a JSplitPane component in Java, one should follow these steps:

  • Create a new JFrame.
  • Call frame.getContentPane().setLayout(new FlowLayout()) to set flow layout for the frame.
  • Create two String arrays that will containt the contents of the two areas of theJSplitPane.
  • Create two JScrollPane components.
  • Create a new JSplitPane with the above JScrollPane components in each side.
  • Use frame.getContentPane().add(splitPane) to add the spilt pane to your frame
package com.javacodegeeks.snippets.desktop;

import java.awt.FlowLayout;
import java.awt.Panel;

import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JSplitPane;

public class CreateJSplitPaneExample {

	private static void createAndShowGUI() {

		// Create and set up the window.
		final JFrame frame = new JFrame("Split Pane Example");

		// Display the window.
		frame.setSize(200, 200);

		// set flow layout for the frame
		frame.getContentPane().setLayout(new FlowLayout());

		String[] options1 = { "Bird", "Cat", "Dog", "Rabbit", "Pig" };
		JComboBox combo1 = new JComboBox(options1);

		String[] options2 = { "Car", "Motorcycle", "Airplane", "Boat" };
		JComboBox combo2 = new JComboBox(options2);

		Panel panel1 = new Panel();

		Panel panel2 = new Panel();

		JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, panel1, panel2);
		// JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT, panel1, panel2);



	public static void main(String[] args) {

  //Schedule a job for the event-dispatching thread:

  //creating and showing this application's GUI.

  javax.swing.SwingUtilities.invokeLater(new Runnable() {

public void run() {
