I submitted a bug/suggestion with Trolltech some time ago about adding
QToolTIp::showDocument( QPoint, QTextDocument ) or something of the
sort, which could let you use custom resources you've added to the
document yourself; as this was the second or third time I had to
reimplement QToolTip in order to show thumbnails of internal
application data. The response I received was that they hadn't
considered such a method, but would look into it if many people
requested it. I've referred them to this thread. (Although, many of
the ideas in it are even beyond the scope of simply passing in a
QTextDocument).
