Hi Charles,
The spacebar event is caught by the manipulator - if you "throw" the
model to make it spin, hitting space should stop the rotation.
Basically, all events are pushed onto the OSG event queue by the calls
to getEventQueue()->*. Internally, each event handler that has been
added to the view (the manipulator, the stats handler etc) is given a
chance to handle each event as it is taken off the queue. The catch is
that some handlers deal with an event, then stop that event from begin
passed onto any further handlers (typically, this is a good thing ...).
I've had a quick look at the latest SVN and it appears as though the key
events are caught by the OnKey* handlers, but for some reason the stats
are not being displayed ... I don't have time to look further into this
today, but I will over the weekend ... unless some one else has any
ideas first.

I don't know -- whichever osg event handler it is that *does*
successfully
catch the spacebar event. I recompiled the osgviewerWX example with
my 3 line addition and it works, but if don't tell it to use key=32 it
doesn't
work. When there are no special graphics contexts, of course, the "s"
key
toggles the stats just fine, so my guess was that wx is doing something
with the s-key event. I guess by "osg event handler", therefore, i
just mean
the StatsHandler.
