Hi Martin,
You can't reuse (osgGA::GUIEventAdapter::DRAG) case in handle() because the scroll event needs to be cleared.
That's how we do it, and I didn't see any problems... Our code is quite
close to:
case (osgGA::GUIEventAdapter::SCROLL):
case (osgGA::GUIEventAdapter::DRAG):
{
addMouseEvent(ea);
if (calcMovement()) aa.requestRedraw();
aa.requestContinuousUpdate(false);
_thrown = false;
return true;
}
and it works great. Perhaps there's something else that is different.
We've subclassed TrackballManipulator and replaced most of its
functionality with similar (but not quite identical) code...
I like the idea of reusing the drag and 'dy' - I have rewritten it with that
approach. It does lead to having to declare a couple of variables before they
can be set which seems to be against OSG house style (and is generally a bad
idea)
It's not that bad, since you only have an if and an else it can't really
fall through the cracks. As with any programming convention I tend to be
pragmatic...
J-S
