I would like to alter the following code so that showNewLevel() is able to return the input[]. If I just alter the signature and add the return as it is I get a return value of null I think because the actionlistener isn't called when I think it is. How can I make this method have similar functionality to JOptionPane.ShowInputDialog()?

It seems that I only needed to set my dialog as modal and I have the functionality I require.
