If you are doing this at startup and you don't have a "good" shell / 
display (which I did not with my login dialog) then the following code 
will center on the 1st monitor in a multiple monitor setup or only 
monitor if you only have a single.

   Monitor [] ma = display.getMonitors();
    if (ma != null)
      m_shell.setLocation((ma[0].getClientArea().width - pixel.width) / 
2, (ma[0].getClientArea().height - pixel.height) / 2);

In this case I have the height / width of the dialog stored in the 
"pixel" variable.
