 That's not the right way to do it. There's no reason why the systray should 
be a toplevel window, it's part of the Plasma window (you also don't create 
e.g. pushbuttons as toplevel windows that just happen to be in the right 
position WRT the dialog).

 As far as I understood the systray widget cannot be handled normally like 
others for whatever internal reasons, so if you need to keep it separately, 
at least keep it in the toplevel Plasma window. That is, set the Plasma 
toplevel widget as its parent, keep it as the topmost child and keep the 
position relative to it.
