addActionListeners() not recognized ENTER key event for a JTextField

Hello, all. I have the following code in my init() method:

Code :

---

		friend = new JTextField(TEXT_FIELD_SIZE);
		friend.setActionCommand("Add Friend");
		add(friend, WEST);
		add(new JButton("Add Friend"), WEST);
 
		canvas = new FacePamphletCanvas();
		add(canvas);
 
		addActionListeners();

---

and the following code in my actionPerformed submethod:

Code :

---

    public void actionPerformed(ActionEvent e) {
    	String cmd = e.getActionCommand();
    	if(cmd.equals("Add")) addProfile();
    	if(cmd.equals("Delete")) deleteProfile();
    	if(cmd.equals("Lookup")) lookupProfile();
 
    	if(cmd.equals("Change Status")) changeStatus();
    	if(cmd.equals("Change Picture")) changePicture();
    	if(cmd.equals("Add Friend")) addFriend();
	}

I'm using Eclipse as my compiler. I used the debugging tools to discover that when I hit the ENTER key, my program is not recognizing the ActionEvent. It does recognize the ActionEvent when I hit the JButton with the same ActionCommand. Any suggestions? Thank you!

Assuming you've added the ActionListener to the JTextField, the JTextField must have focus to fire the event. Focus occurs when you type inside, or by calling requestFocus

Thanks, copeg. But when I run the program, I do click in the JTextField, type a string, and then hit ENTER. Nothing happens. When I hit the JButton that has the same CommandAction, then the event fires. Any other ideas why my program isn't recognizing the ENTER key as a CommandAction event?

Post an SSCCE that demonstrates the behavior. And make sure you have added the ActionListener to the JTextField.

Pardon my newbie-ness... what's an SSCCE? Also, is there a different way to add the ActionListener to the JTextField specifically? I thought I had already added it properly as demonstrated in the 1st set of code above. Thank you so much for your continued help.

Short, Self Contained, Correct Example - see the link in my signature, or just google the acronym.

You call a method addActionListeners(), and did not post the code. We can only guess what you did...hence the request for an SSCCE

I hope this is an SSCCE. I think you should be able to run this and recreate my results. Thanx again for any help. :)

Code :

---

import acm.program.*;
import java.awt.event.*;
import javax.swing.*;
 
public class TestActionListeners extends ConsoleProgram {
 
	public void init() {
		JTextField status = new JTextField(25);
		status.setActionCommand("Change Status");
		add(status, WEST);
		add(new JButton("Change Status"), WEST);
 
		addActionListeners();
	}
 
	public void actionPerformed(ActionEvent e) {
		String cmd = e.getActionCommand();
		if(cmd.equals("Change Status")) println("Status changed.");
	}
 
}

Not an SSCCE....where is the addActionListeners method defined? Are you required to use the class ConsoleProgram (it is a 3rd party library, and IMO for beginners it defeats the process of learning the ins and outs of how to create a GUI)? And where in that method could it add an ActionListener to the local variable status? Recommend reading the following? How to Write an Action Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)

Thanks, copeg. I will check out the reading and go from there. :)
