Need help with QTreeView/QAbstractItemModel

[wysota]

You should emit dataChanged whenever the data of existing items change and layoutChanged whenever you add or remove items (or reorder them).

Bah, I've been trying for a while now, and I can't figure out how to get the index() and parent() functions to work. Basically all I'm doing is reading a qstring returned from a qdailog and adding it to a qstringlist. How do I connect this to the QAbstractItemModel?

[wysota]

IMO your index() should look like so:

QModelIndex serverListModel::index(  int row, int column, const QModelIndex &parent ) const {
 return createIndex(row, column);
}

QModelIndex serverListModel::index(  int row, int column, const QModelIndex &parent ) const {
 return createIndex(row, column);
}

To copy to clipboard, switch view to plain text mode 

For parent and a "flat" (tabular) model you can always return QModelIndex() as all items have an invalid parent.
