[Interest] Cannot enable dragging from QAbstractItemModel

[Etienne Sandré-Chardonnal]

Dear all,

After successfully enabling drag from a QAbstractListModel, I am trying to
do the same with a tree model.

Here is what I did:

//In constructor:
setSupportedDragActions(Qt::CopyAction);


//Qt::ItemFlags Model::flags(const QModelIndex & index) implementation
return Qt::ItemIsEnabled | Qt::ItemIsSelectable | Qt::ItemIsDragEnabled;

I also implemented mimeData() , but it gets never called anyway.

Dragging is not triggered, and items are only selected.

I do not know what to do for enabling drag support? It works well with
QAbstractListModel

Thanks,

Etienne
