Hi Roedy,
I think that the emphasis for this Q was indeed on the JTextArea, not
a Dialog. That is if I read you correctly.

Hi Knute and Roedy,

My solution:

From:

A subsection of this text above: "Adding the Editable Text Area"; a
code snip
adapted for my solution and this scroll code snip inserted in the
original code above:

  /** Create a frame with JTextArea and a menubar
    * with a "File" dropdown menu.
   **/
  FileChooseApp (String title) {
    super (title);

    Container content_pane = getContentPane ();

    // Create a user interface.
    content_pane.setLayout ( new BorderLayout () );
    fTextArea = new JTextArea ("");

    //added this code snip for scroll
    content_pane.add (fTextArea, "Center");
    fTextArea.setEditable(true);
    JScrollPane areaScrollPane = new JScrollPane(fTextArea);// added
this for scroll
 
areaScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); //
added this for

scroll
    areaScrollPane.setPreferredSize(new Dimension(200, 175));// added
this for scroll
    areaScrollPane.setBorder(BorderFactory.createTitledBorder("Enter
or Edit Text:"));// added this for scroll
    content_pane.add(areaScrollPane); // added this for scroll

   //ended this code snip for scroll

    // Use the helper method makeMenuItem
    // for making the menu items and registering
    // their listener.
    JMenu m = new JMenu ("File");

    // Modify task names to something relevant to
    // the particular program.
    m.add (fMenuOpen = makeMenuItem ("Open"));
    m.add (fMenuOpen = makeMenuItem ("Save"));
    m.add (fMenuClose = makeMenuItem ("Quit"));

    JMenuBar mb = new JMenuBar ();
    mb.add (m);

    setJMenuBar (mb);
    setSize (400,400);
  } // ctor

Thanks
