[osg-users] OperationsThread(OSG 2.0) example

[Rahul Srivastava]

Hi Robert,

I looked at the Viewer code also but could not figure out how to make 
Operation work without the graphics context. Here's a sample program I 
wrote. Is there something wrong with what I'm doing?

The program seems to wait for a condition at the line "t->add(...)" and 
doesn't respond.

--snip--

OpenThreads::Thread::Init();

osg::ref_ptr<osg::OperationsThread> t = new osg::OperationsThread;

osg::ref_ptr<osg::Operation> o = new TestOperation;

t->add(o.get(), false);

t->startThread();

--snip--

Regards,
