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
addthe 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.
Thanks!
