The SoQtConstrainedViewer class is the superclass for viewers with constrains on the viewpoint.
This abstract viewer class adds new methods to keep the camera in an upright position according to some arbitrary up-direction. The up-direction can be decided by either the application programmer (by using SoQtConstrainedViewer::setUpDirection()) or the end-user, through interaction mechanisms defined by the subclasses.
Constructor.

Virtual destructor.
Set up-direction vector for the camera viewpoint.

Set the camera we want the viewer to manipulate when interacting with the viewer controls.
The camera passed in as an argument to this method must already be part of the viewer's scenegraph. You do not inject viewpoint cameras to the viewer with this method.
You should rather insert a camera into the scene graph first (if necessary, often one will be present already), then register it as the camera used by the viewer controls with this method.
If the application code doesn't explicitly set up a camera through this method, the viewer will automatically scan through the scenegraph to find a camera to use. If no camera is available in the scenegraph at all, it will set up it's own camera.
