Detaillierte Beschreibung
Dieses Modell macht die Zeilen des Quellmodells zu Spalten des Proxy-Modells und umgekehrt.
Handelt es sich bei dem Modell um einen Baum, werden auch die Eltern umgewandelt. Wenn z.B. ein Index im Quellmodell den Elternteil "index(2,0)" hat, wird er im Proxy-Modell den Elternteil "index(0,2)" haben.
