void viewOpened(int idNum)
This method must be exposed by managers (but not tools). It is called whenever a new SDM view is opened (either by the user or by another client). The argument idNum is the unique identifier for the newly opened view.
If the client needs to keep track of the views that are opened or transfer information to newly opened views, this method provides the means to do so. This method may do nothing, but it must always be exposed by managers.
