Java OptionPane displays first. Need to launch after program is launched

Question

Object[] options = { "option 1", "option2",
                    "option 3" };
            result = JOptionPane
                    .showOptionDialog(this,
                            "Welcome! ","Welcome Message",
                            JOptionPane.YES_NO_CANCEL_OPTION,
                            JOptionPane.QUESTION_MESSAGE, null, options,
                            options[0]);

I Would like to show this JOptionPane after program is launched. But even if i do it at the end of constructor its invokes first before other components. Is there any way to do it?

Answer 1

It appears that you are calling this prior to the call to "setVisible(true)" on the rest of your application.

I would recommend you take a look at "SwingUtilities.invokeLater()"

to ensure that you code option pane is invoked at a "Later" time on the EDT.

Answer 2

If you're using Swing UIs, you can put the code inside windowOpened event of the JFrame or JDialog .

public void windowOpened(java.awt.event.WindowEvent evt) {
    // your JOptionPane
}

Then your JOptionPane will be shown after the Window becomes visible. I hope this helps.
