73 /** @descr
74     <p>This class essentially provides the text and view forwarders. If
75     no SdrView is given, this class handles the UNO objects, which are
76     currently not concerned with view issues. In this case,
77     GetViewForwarder() always returns NULL and the underlying
78     EditEngine of the SvxTextForwarder is a background one (i.e. not
79     the official DrawOutliner, but one created exclusively for this
80     object, with no relation to a view).
81     </p>
82 
83     <p>If a SdrView is given at construction time, the caller is
84     responsible for destroying this object when the view becomes
85     invalid (the views cannot notify). If GetViewForwarder(sal_True)
86     is called, the underlying shape is put into edit mode, the view
87     forwarder returned encapsulates the OutlinerView and the next call
88     to GetTextForwarder() yields a forwarder encapsulating the actual
89     DrawOutliner. Thus, changes on that Outliner are immediately
90     reflected on the screen. If the object leaves edit mode, the old
91     behaviour is restored.</p>
