void osg::GraphicsThread::add (  Operation *  operation, bool  waitForCompletion = false )

Add operation to end of OperationQueue, this will be executed by the graphics thread once this operation gets to the head of the queue.

virtual int osg::GraphicsThread::cancel (   )  [virtual]

Cancel this graphics thread.

osg::ref_ptr<Operation> osg::GraphicsThread::getCurrentOperation (   )  [inline]

Get the operation currently being run.

bool osg::GraphicsThread::getDone (   )  const [inline]

void osg::GraphicsThread::remove (  const std::string &  name  )

Remove named operation from OperationQueue.

void osg::GraphicsThread::remove (  Operation *  operation  )

Remove operation from OperationQueue.

void osg::GraphicsThread::removeAllOperations (   )

Remove all operations from OperationQueue.

virtual void osg::GraphicsThread::run (   )  [virtual]

Run does the graphics thread run loop.
