Create read-only (non-editable) JTextField

In this example we are going to see how to create read-only JTextFields in Java Desktop Applications. This is very useful in many occasions.

In order to create a non editable JTextField, all you have to do is:

  • Create a class that extends JFrame.
  • Create a new JTextField.
  • Use setEditable(false) that sets the specified boolean to indicate whether or not this textfield should be editable.
  • Use add to add the field to the frame.

 
Let’s see the code:

package com.javacodegeeks.snippets.desktop;

import java.awt.FlowLayout;

import javax.swing.JFrame;
import javax.swing.JTextField;

public class CreateReadOnlyJTextField extends JFrame {

	private static final long serialVersionUID = 1L;

	public CreateReadOnlyJTextField() {

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

		// create JTextField
		JTextField field = new JTextField();
		field.setText("Java Code Geeks");

		// Sets the specified boolean to indicate whether or not
	    // this textfield should be editable.
		field.setEditable(false);

		// add textfield to frame
		add(field);

	}

	private static void createAndShowGUI() {

  //Create and set up the window.

  JFrame frame = new CreateReadOnlyJTextField();

  //Display the window.

  frame.pack();

  frame.setVisible(true);

  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

	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(); 

}

  });
    }

}

 
This was an example on how to create read-only (non-editable) JTextField.
