JTextField

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.
