currently not. And it is not as straight forward as it might look like as you would have to share OpenSG's bookkeeping information between the two contexts. And than there is the multi-threading structure of the rendering backend to be taken care of. I started re-factoring parts but haven't pushed it that far. The easiest solution for now might be to work with a single PassiveWindow over two application windows, but I have to check if this really works. And it might lack some features. Another might be a something like a lightweight window decorator that keeps one master window (context) and swaps it through slave windows (reusing the master context). With the new year break coming up in these parts of the world ;) I'll put it on my to think about list ;). kind regards gerrit -- Gerrit Voß 盖瑞客 ------------------------------------------------------------ Fraunhofer IDM @ NTU 南洋理工大学, Nanyang Technological University, (NTU) 新加坡, Singapore ------------------------------------------------------------ ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
