[osg-users] osgviewerQt integration required

[Robert Osfield]

HI Manish,

I could be a Qt change in behavior that it's setting the context up or
managing the threads in an different way.  Qt's this moving goal posts
with trying to integrate.  Each rev it the way Qt works w.r.t OpenGL
shifts a bit.

One thing you could try is OSG-svn/trunk or the OSG-3.3.7 dev release.
There is chance that revisions to osgQt help keep track of the later
versions of Qt better.

However, I'm not personally a Qt expert.  I have to defer to others to
provide expertise.

Robert.
