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