[osg-users] Matrix Manipulators and set coordinate frame callback. Different behavior in 2.4?

[Dorosky, Christopher G]

Hello all,

Under OSG 1.2, I controlled the orientation of an osgGA manipulator
through the use of a coordinate frame callback.

Under 2.4, I am using the same exact code, but the callback never
happens.

Here is the code snippet. Viewer is osgProducer (yes, still).
This loop runs 4 times.

Viewer->getKeySwitchMatrixManipulator()->setHomePosition(eyeECEF,
centerECEF, upECEF, false);
	cECEFFrameCB *cb = new cECEFFrameCB;
	
for(unsigned int i = 0; i<
Viewer->getKeySwitchMatrixManipulator()->getNumMatrixManipulators();
i++)
	{
		osgGA::MatrixManipulator *mm =
Viewer->getKeySwitchMatrixManipulator()->getMatrixManipulatorWithIndex(i
);
		if(mm) 
		{
			mm->setCoordinateFrameCallback(cb);
			mm->setHomePosition(eyeECEF, centerECEF, upECEF,
false);
		}
	}

Where the ECEFFrameCB is derived from the
osgGA:MatrixManipulator::CoordinateFrameCallback.

I put a print in there, and it is never called.
Has this functionality been disabled?

What I am trying to do is set the up, side, and front vectors so that
the manipulator behaves better.

Thanks,

Chris
