 Yes, it's so. NEdit doesn't have support for this property.

 I personally think that embedding an application that itself doesn't support 
being embedded will always be an ugly hack, whichever way you do it. For this 
NEdit case, you could try searching windows for NEdit's WM_CLASS property 
(xprop | grep WM_CLASS to see what I mean). The Xlib function is called 
XGetClassHint(), and you could possibly also read 
http://tronche.com/gui/x/icccm/sec-4.html#s-4.1.2.5 , and be aware of the 
fact that many apps have this screwed up, and set it differently than the 
specification says.
