JDialog for status display . .

Question

I just want to implement a status dialog. How to show a JDialog which blocks the user input but allow the parent window processing its own work?

Answer 1

You can use a modal JDialog or JOptionPane (which really is nothing more than a specialized modal JDialog) for this, just be sure to

• the work is not to be done in a parent "window"
• but rather it should be done in a background thread
• and this thread should be started prior to setting the dialog visible.
• Use a SwingWorker for this background thread, and then your dialog can display quantitative progress information by adding a PropertyChangeListener and having the SwingWorker update its progress property.

Answer 2

JOptionPane with JOptionPane.showXXXDialog(); static methods, what else ?

Answer 3

You can create and customize different kind of dialog using JOptionPane. Have a look at JOptionPane Features. Also, have to look at

• JDialog(Dialog owner, boolean modal)

• ModalityTypes

• The best of all could be JOptionPane
