218 |* Beschreibung Bei einem Absatzgebunden Fly kann es durchaus sein,
219 |* das der Anker auf die Veraenderung des Flys reagiert. Auf diese
220 |* Reaktion hat der Fly natuerlich auch wieder zu reagieren.
221 |* Leider kann dies zu Oszillationen fuehren z.b. Der Fly will nach
222 |* unten, dadurch kann der Inhalt nach oben, der TxtFrm wird kleiner,
223 |* der Fly muss wieder hoeher woduch der Text wieder nach unten
224 |* verdraengt wird...
225 |* Um derartige Oszillationen zu vermeiden, wird ein kleiner Positions-
226 |* stack aufgebaut. Wenn der Fly ein Position erreicht, die er bereits
227 |* einmal einnahm, so brechen wir den Vorgang ab. Um keine Risiken
228 |* einzugehen, wird der Positionsstack so aufgebaut, dass er fuenf
229 |* Positionen zurueckblickt.
230 |* Wenn der Stack ueberlaeuft, wird ebenfalls abgebrochen.
231 |* Der Abbruch fuer dazu, dass der Fly am Ende eine unguenste Position
232 |* einnimmt. Damit es nicht durch einen wiederholten Aufruf von
233 |* Aussen zu einer 'grossen Oszillation' kommen kann wird im Abbruch-
234 |* fall das Attribut des Rahmens auf automatische Ausrichtung oben
235 |* eingestellt.
