Are you maybe missing the explicit moc include?

#include "standarddocumentationview_qtb.moc"

or was it

#include "moc_standarddocumentationview_qtb.cpp"

?

Google and test those, maybe it helps.

But in principle, I would claim that this pattern above isn't nice in the 
first place. Rather, have the standarddocumentationview.h include either the 
_qtb or the _web.h, and then have accompanying .cpp files for those headers. 
That should fix it.
