Here I attached a test program with my very 3 problems with osgIntrospection.
(test1) osgIntrospection::Value( osg::Vec3(1,2,3) ) is not "valid",
because the osgIntrospection::Type returned is different from the type
returned by osgIntrospection::Reflection::getType("osg::Vec3"). So,
how do I pass a vec3 to a Value ?
(test2) I get a very strange exception without doing anything? when I
try to get the method setText from osgText::Text type.
(test3) The previous mail, how to access a static method (I wondering
if the static method is been reflected) of a class?
Thank you in advance !
