Hi Gerrit,
the "editFieldPtr" are currently not necessary but they were there
with both versions of OpenSG.
I will try the current OpenSG version again,
but need to recompile it first.
In the conversion into a cluster application I would like to use
the ClusterServer object without a window.
Using it with a GLUT window works fine!
server = new OSG::ClusterServer(win,
name,
connectionType,
address,
servicePort,
serviceGroup);
Using it with win=NULL and "server->doSync(true);" instead of
"server->render(ract);" seems not to be sufficient.
So what is necessary to make it work with a minimal window class
(without any rendering)?
Thanks,
Christoph
