    public class MessageBox
extends Window
    This class implements a scrollable message box window with customized buttons, delayed unpop and scrolling text.
    for example, to create an automatic unpop after 5 seconds, do: 
       MessageBox mb = new MessageBox("TotalCross","TotalCross is the most exciting tool for developing totally cross-platform programs.",null);
   mb.setUnpopDelay(5000);
   mb.popup(mb);

      • buttonKeys

        public int[] buttonKeys
        If you set the buttonCaptions array in the construction, you can also set this public field to an int array of the keys that maps to each of the buttons. For example, if you set the buttons to {"Ok","Cancel"}, you can map the enter key for the Ok button and the escape key for the Cancel button by assigning: 
         buttonKeys = new int[]{SpecialKeys.ENTER,SpecialKeys.ESCAPE};
        Note that ENTER is also handled as ACTION, since the ENTER key is mapped to ACTION under some platforms.
