63 : /** @descr
64 : <p>This class essentially provides the text and view forwarders. If
65 : no SdrView is given, this class handles the UNO objects, which are
66 : currently not concerned with view issues. In this case,
67 : GetViewForwarder() always returns NULL and the underlying
68 : EditEngine of the SvxTextForwarder is a background one (i.e. not
69 : the official DrawOutliner, but one created exclusively for this
70 : object, with no relation to a view).
71 : </p>
72 :
73 : <p>If a SdrView is given at construction time, the caller is
74 : responsible for destroying this object when the view becomes
75 : invalid (the views cannot notify). If GetViewForwarder(sal_True)
76 : is called, the underlying shape is put into edit mode, the view
77 : forwarder returned encapsulates the OutlinerView and the next call
78 : to GetTextForwarder() yields a forwarder encapsulating the actual
79 : DrawOutliner. Thus, changes on that Outliner are immediately
80 : reflected on the screen. If the object leaves edit mode, the old
81 : behaviour is restored.</p>
