Hi,
In GUIEventHandler class the handle function is like :
handle(const osgGA::GUIEventAdapter& ea,osgGA::GUIActionAdapter& aa,
osg::Object*, osg::NodeVisitor* nv);
But I implement it and find NodeVisitor nv is always empty. How can I set a
nodeVisitor to this function? I trace the code and find this function is called
by viewer class with
Viewer::eventTraversal()
{
...
(*hitr)->handleWithCheckAgainstIgnoreHandledEventsMask( *event, *this, 0, 0);
....
}
it looks like the nodeVisitor is always empty.
Thanks in advance
Hui
