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