A while ago I tried to display swing dialog box to get user input numbers. I had some trouble but got help from a few of the processing veterans on the discussion board that I can use noLoop() and loop() to enclose a swing dialog box. It works perfectly.

I've done some reading and found how to invoke some code on separate threads by using the following syntax:

SwingUtilities.invokeLater(new Runnable() {  
     public void run() {
 
        javax.swing.JOptionPane.showMessageDialog(frame,"Hello!");
     }  
   });  

This way does work without adding noLoop() and loop(). My question here is: could the processing veterans comment on the pros and cons of this method? I'd like to write a stable program. Thank you! ^_^
