Delphi-PRAXiS - Einzelnen Beitrag anzeigen - Liste von vielen unterschiedlichen Grafikobjekten mit unterschiedlichen Properties

**Bjoerk**

Ich hab eine Liste von vielen unterschiedlichen Grafikobjekten mit unterschiedlichen Properties. Die published Werte markierter Objekte sollen nun editiert werden können. Die Frage wäre, wie macht man das denn am besten?

Beispielklasse:

zusammenfalten · markieren
