Hi,

If it were me, I'd use the deprecated function since it won't be removed 
in GTK+3 and by the time your code is ported to GTK+4, you'll have much 
larger things to worry about.

Another solution would be to just use Xlib directly and read the 
_NET_ACTIVE_WINDOW[0] property on your own, and/or copy the code from 
the deprecated function's implementation[1].

As far as wnck being heavy on resources, I'm not sure what that means, 
but since Xfwm4 is already using it[2], I don't think it will add any 
additional memory overhead (unless you're not using Xfwm4 or anything 
else that uses libwnck), if that's what you meant.
