Hi all.
I am trying to get a WindowManager to work "ontop" of a CompositeViewer
with all its views inside one window.
I have managed to get it up and running but the widgets act wierd, I
can turn them like if they were a node.
Is there a way to achieve this or do i have to create a WindowManager
for every view in the CompositeViwer and
how do i get widgets to move from a view to the other.
I found a similar question on
http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2010-February/039025.html
but nobody seems to have any answers.
Regards Nikola R.
