JTextArea as a pop up

[Priyatham Anisetty]

Hi I am wondering if I can Pop up a JTextArea as PopUp , so the user will be able to edit the text in the textarea.


Thanks in Advance .

What happened when you tried? To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates your problem.

The short answer is yes. Here is a sample:

        JButton popUpButton = new JButton("Pop Up");
        menuBar.add(popUpButton);
        final JDialog dialog = new JDialog();
        popUpButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                dialog.setVisible(true);
            }
        });
        dialog.setModal(true);
        dialog.add(new JTextArea());

This will create button on the menuBar that pops up a modal dialog box that contains a JTextArea. Of course, you'll need to set your bounds etc.

The question was about using a popup, not a modal JDialog. Apart from that, please DontBeACodeMill <- link

No! Use an appropriate layout manager.

So you prefer the long answer, but you don't want me to be a CodeMill. A Popup object does not allow a user to edit the JTextArea, but there are several ways to get a Pop Up, popup or PopUp without it being of type javax.swing.Popup. One is a JDialog. If you want to keep the focus on the pop up until the user is done entering the text, you can set modal, but that is simply an option. In my sample, I did not set any layout manager, size, text, etc. that I leave for you.

Depends what you mean by 'the long answer'

Did you go through the link to find why?

Wrong. It does not by default allow the user to edit the JTextArea. Changing that behavior is just a matter of invoking the relevant methods. One method, actually.

I wouldn't classify a JDialog as a popup. JPopupMenu, maybe. But the question was about Popup misspelled PopUp, and my initial response was appropriate to the question and could elicit some clarification and a better framed question, benefiting Priyatham in the process.

Your copy/pastable code snippet was akin to spoonfeeding, which is why I pointed you to the FAQ page.

Not really relevant, but OK.

I quote you again:

That isn't a suggestion to use an appropriate layout manager.

Moreover, your code snippet retains the default BorderLayout of the JDialog, and setBounds(...) would be ineffective.

Well I learned something. I didn't realize you could edit inside a Popup, but now I realize you have to have the Popup within the Application's window, then it will allow you to edit it. By default it does allow you to edit the textArea, but only if the Popup is positioned correctly.

Isn't that what forums are for?

I didn't know that, so I've learned something too.

That's not a constraint.
One -- to the text area
Two
Three -- check not null
Four -- set true
