Oh great, this is exactly the problem I have now. I divided the window into three viewports, and assigned an extra trackball navigator to the camera of each viewport.
I was a bit lazy, so the first VP is still managed by the SSM and its Navigator. However, in my QT window I check which VP has been hit. No I tried different combinations to pass to the mouse methods of the ssm or remaining navigators, respectively, and the following happens: VP 1 (from SSM) doesn't show anything :-( VP 2 & 3: Rotating somehow works, zooming too, but panning makes the scene (a torus) vanish and I can't find it again. So here's what I observed: In Navigator::calcDeltas, getPixelWidth() of the VP is used, but getPixelLeft() is neglected. In Navigator::setCameraTransformation(), the matrix of the given Node is not copied to the trackball matrix. Has there been any progress since Allan started this thread in March?
