[Papervision3D] mouse hand cursor, useOwnContainer and viewportLayers - what am I doing wrong?

[Caudwell]

Hello,

I'm trying to conditionally show a hand cursor over selected DO3D objects.

Each object has useOwnContainer = true

After reading Andy Zupko's ViewportLayer code I thought the following would
work:


    do3D.container.buttonMode = true;



but it doesn't. I wondered if it might be to do with the viewport layer
being generated after each render, so I tried:


    layer:ViewportLayer = viewport.getChildLayer(do3d, true);
    layer.buttonMode = true;

still no joy - though I did notice that after this code the container
property of do3D was always non-null (since sometimes the code I'm using to
do this will run before the object has first rendered)


Can anyone see anything wrong with this / point me to any other way of
controlling the hand cursor?



p.s. Also, is there any way to re-purpose the Quad Tree sorting and apply it
to viewport layers, rather than the objects inside a viewport layer?
