/*=========================================================================

Jeder, der an Intanzen der Klassen SfxStyleSheetBasePool oder am
SfxStyleSheetBase strukturelle �nderungen vornimmt, mu� diese �ber
<SfxStyleSheetBasePool::GetBroadcaster()> broadcasten. Daf�r Gibt es die
Klasse <SfxStyleSheetHint>, die eine Action-Id und einen Pointer auf einen
<SfxStyleSheetBase> erh�lt. Die Actions sind:

#define SFX_STYLESHEET_CREATED      // neu
#define SFX_STYLESHEET_MODIFIED     // ver"andert
#define SFX_STYLESHEET_CHANGED      // ausgetauscht
#define SFX_STYLESHEET_ERASED       // gel"oscht

Es machen bereits die folgenden Methoden von sich aus:

SfxStyleSheetHint(SFX_STYLESHEET_MODIFIED) aus:
   SfxStyleSheetBase::SetName( const String& rName )
   SfxStyleSheetBase::SetParent( const String& rName )
   SfxStyleSheetBase::SetFollow( const String& rName )

SfxSimpleHint(SFX_HINT_DYING) aus:
   SfxStyleSheetBasePool::~SfxStyleSheetBasePool()

SfxStyleSheetHint( SFX_STYLESHEET_CREATED, *p ) aus:
   SfxStyleSheetBasePool::Make( const String& rName,
   SfxStyleFamily eFam, USHORT mask, USHORT nPos)

SfxStyleSheetHint( SFX_STYLESHEET_CHANGED, *pNew ) aus:
   SfxStyleSheetBasePool::Add( SfxStyleSheetBase& rSheet )

SfxStyleSheetHint( SFX_STYLESHEET_ERASED, *p ) aus:
   SfxStyleSheetBasePool::Erase( SfxStyleSheetBase* p )
   SfxStyleSheetBasePool::Clear()
