Yeah, I was starting to come to this realization after I posted, by heading back
to the docs and reading what a QMoveEvent object actually is
(http://doc.qt.io/qt-5/qmoveevent.html), specifically the
line:  Move events are sent to widgets that have been moved to a new 
position relative to their parent.

I might have to, but I definitely don't really like this solution since it breaks
encapsulation. What I'm looking at now is since the widget I'm popping up
is supposed to behave somewhat similar to a popup menu, that I should 
probably just hide it whenever focus leaves it. That's probably more what
users would expect to happen, and makes it easier on me anyways.
