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