String SfxViewFrame::UpdateTitle()

/*	[Beschreibung]

	Mit dieser Methode kann der SfxViewFrame gezwungen werden, sich sofort
	den neuen Titel vom der <SfxObjectShell> zu besorgen.

	[Anmerkung]

	Dies ist z.B. dann notwendig, wenn man der SfxObjectShell als SfxListener
	zuh"ort und dort auf den <SfxSimpleHint> SFX_HINT_TITLECHANGED reagieren
	m"ochte, um dann die Titel seiner Views abzufragen. Diese Views (SfxTopViewFrames)
	jedoch sind ebenfalls SfxListener und da die Reihenfolge der Benachrichtigung
	nicht feststeht, mu\s deren Titel-Update vorab erzwungen werden.


	[Beispiel]

	void SwDocShell::Notify( SfxBroadcaster& rBC, const SfxHint& rHint )
	{
		if ( rHint.IsA(TYPE(SfxSimpleHint)) )
		{
			switch( ( (SfxSimpleHint&) rHint ).GetId() )
			{
				case SFX_HINT_TITLECHANGED:
					for ( SfxViewFrame *pTop = SfxViewFrame::GetFirst( this );
						  pTop;
						  pTop = SfxViewFrame::GetNext( this );
					{
						pTop->UpdateTitle();
						... pTop->GetName() ...
					}
					break;
				...
			}
		}
