Create JScrollPane example

In this example we are going to see how to create a JScrollPane container in a Java Desktop Application. This is one of the most important components in a GUI application, especially when your client code has to handle and to display a large amount of data.

It is very simple to create a JScrollPane. All you have to do is:

  • Create a new JFrame.
  • Create a JTextArea.
  • Call new JScrollPane(textArea) to create a scrollable Text Area. Remember that JScrollPane is a container and you can add any component you want to it to make it scrollable.
  • Use setHorizontalScrollBarPolicy and setVerticalScrollBarPolicy to set the vertical and horizontal scroll bar policies.

Let’s see the code:

package com.javacodegeeks.snippets.desktop;

import java.awt.FlowLayout;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

public class CreateJScrollPaneExample {

	private static final long serialVersionUID = 1L;

	private static void createAndShowGUI() {

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

		// Display the window.
		frame.setSize(200, 200);
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

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

		JTextArea textArea = new JTextArea(5, 5);
		JScrollPane scrollableTextArea = new JScrollPane(textArea);

		scrollableTextArea.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
		scrollableTextArea.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);

		frame.getContentPane().add(scrollableTextArea);

	}

	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() {

    createAndShowGUI(); 

}

  });
    }

}
