Not sure if I understand your question right: you want to set the
application back to viewing mode as soon as the user messes with the
PanZoomBar (assuming this is what you mean by navToolbar)?

If so, you could just register a listener for the map's moveend event.
This will be triggered with everything that a user can do in the
PanZoomBar.

Or maybe you just want to set the application back to viewing mode
when the user zooms the map using the ZoomBar? In that case, you
register for the zoomend instead of the moveend event.

I hope this answer helps.

Andreas.
