I have added transitions to the InteractorInitializeState with 
ValidAddObjectInput. 
You should be able to add spatial objects after initializing the interactor.

I have committed a fix.  Now, when you set the view in the widget, the 
reporter will be also connected.  So you can add an
observer to the widget and you will be able to listen to 
TransformModified events.

For testing, I have added code snippet that observes TransfomModified 
event and outputs the translation parameter
in OneViewAndTrackingUsingQTWidget.

I have added RequestSetRendererBackgroundColor( ... ) method.

Let me know if you see other issues.

Thanks
