Help with QAbstractProxyModel

[killerwookie99]

Wow, lol ok, so I see now.

On your second example, what exactly is this doing:

const QAbstractProxyModel *proxy = qobject_cast<const QAbstractProxyModel*>(index.model());
 
while(proxy!=0){
  index = proxy->mapToSource(index);
  proxy = qobject_cast<const QAbstractProxyModel*>(index.model());
}

const QAbstractProxyModel *proxy = qobject_cast<const QAbstractProxyModel*>(index.model());

while(proxy!=0){
  index = proxy->mapToSource(index);
  proxy = qobject_cast<const QAbstractProxyModel*>(index.model());
}

Is it to keep the proxy and index in sync? Thanks for being patient with me

I already explained it in post #2. It converts the index to the one belonging to a non-proxy model.
