Item order in QAbstractItemModel and QTreeView

[rherzog]

Hi guys,

how can I change the order my items the QTreeView that is backed by a custom Implementation of the QAbstractItemModel?

Do I have to override the two methodes
@bool QAbstractItemModel::removeRows ( int row, int count, const QModelIndex & parent = QModelIndex() ) [virtual]@
and
@bool QAbstractItemModel::insertRows ( int row, int count, const QModelIndex & parent = QModelIndex() ) [virtual]@
so that I can call "removeRow" and "insertRow" on the model?

As far as I know I just have to alter the model apropriately and the view gets updated by the model automatically.

kind regards for your help, reinhart

Take a look on "QAbstractProxyModel":http://qt-project.org/doc/qt-5/qabstractproxymodel.html and "QSortFilterProxyModel":http://qt-project.org/doc/qt-5/qsortfilterproxymodel.html

I have not used them but from the doc it sounds like QSortFilterProxyModel is what may help you.
