Custom QAbstractItemModel & persistentIndexList

dheerendra

HI

I have custom QAbstractListModel called MTModel.
It has 20 rows of data.
Implemented the following functions in model

int rowCount(const QModelIndex &parent = QModelIndex()) const;
 int columnCount(const QModelIndex &parent = QModelIndex()) const;
 QVariant  data(const QModelIndex &index, int role = Qt::DisplayRole) const ;
 QHash<int, QByteArray> roleNames() const;

When I call

QModelIndexList pIndexList = this->persistentIndexList();

It always return 0(zero)

Any idea why it returns zero ? I was expecting this as 20.
Any thing missing here ?

Hi,

Do you create any such indexes ?
If not then that's normal that the list is empty.
