setting location of a dialog relative to the parent

I have a dialog that is opening under certain conditions. What I'd like to have happen is the dialog open at a specific location that is relative to the parent. Currently it is opening at the specified location relative to the upper left corner of the screen. This is pretty annoying since I am running a multi-display setup and my applet is opened on the second display. Any suggestions?

Found that this cannot be done reliably in an applet. consider this solved
