JTextArea on PopUp -JTextArea isn't editable

[Richy76]

I am having an issue with putting a JTextArea on a popup panel. When a button is pressed, a popup should appear with a JTextArea on it. This area should be editable (e.g the user should be able to input text into it). There is a button on the pop up which, when pressed, should make the popup disapear (and will ultimately process the text input by the user).

However I have the problem that the JTextArea is not editable-although I have set it to Edtitable,

textArea.setEditable(true);

and a test in my code states that it is!

if (textArea.isEditable()) {
				System.out.println("text area is editable");
			}

I have used JTextArea before, and I don't usually have a problem making it editable-but there seems to be some issue when it is placed on a pop up.

This is a for a project where I am creating a messaging application. My idea is that the user will press a button to start composing a message. The popup window with the JTextArea will appear and he will input his message. He will then press a send button which will make the window disappear and send the message.

If anyone can point out where I'm going wrong-or else suggest a better way of doing this (perhaps a different set of components to use), I will be very grateful.

thanks in advance.

Here is the full code of my program.

		

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;



public class TextAreaTest extends JPanel implements ActionListener {

	
	protected JTextArea textArea;
	protected JButton myButton;
	protected Popup popup;
	protected JButton anotherButton;
	protected JPanel myPanel;
	private final static String newline = "\n";

	public  TextAreaTest() {
		super(new GridBagLayout());	

		myButton = new JButton("press this"); //popup window appears when this is pressed
		myButton.setActionCommand("myButton");
		myButton.addActionListener(this);
		add(myButton);

		anotherButton = new JButton("anotherButton"); //button on popup. closes popup when pressed
		anotherButton.setActionCommand("anotherButton");		
		anotherButton.addActionListener(this);



		textArea = new JTextArea(5, 20);
		textArea.setEditable(true); //note: set to true!

		textArea.append("this is the text Area");
		JScrollPane scrollPane = new JScrollPane(textArea);

		myPanel = new JPanel(); //this is the popup panel
		myPanel.add(anotherButton);
		myPanel.add(scrollPane);
	}

	public void actionPerformed(ActionEvent e) {

		String command = e.getActionCommand();

		if(command.equals("myButton")) {
			PopupFactory factory = PopupFactory.getSharedInstance();
			popup = factory.getPopup(null, myPanel, 0, 0);

			popup.show();

			if (textArea.isEditable()) { 

				System.out.println("text area is editable");
			}

		} else if (command.equals("anotherButton")) {
			System.out.println("another Button pressed");
			String text = textArea.getText();
			System.out.println(text);

			popup.hide();
		}






	}



	private static void createAndShowGUI() {
		//Create and set up the window.
		JFrame frame = new JFrame("TextDemo");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		//Add contents to the window.
		frame.add(new TextAreaTest());

		//Display the window.
		frame.pack();
		frame.setVisible(true);
	}

	public static void main(String[] args) {
		//Schedule a job for the event dispatch thread:
		//creating and showing this application's GUI.
		javax.swing.SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				createAndShowGUI();
			}
		});
	}


}

Your task calls for a JDialog: How to Make Dialogs.

Thanks. I've had a quick look at that link. Immediately I don't see any mention of JTextArea there

Can you just briefly tell me if it is definitely the case that you can put a JTextArea on a JDialog?

Why not have a look at it again, in depth. A JDialog is a root container just like a JFrame. You can just about put any component in it (actually, like a JFrame, in its contentPane), including JTextAreas, JPanels, ... whatever.
