Do i have to check QModelIndex::isValid() in overriden methods of QAbstractListModel
-
I'm writing a custom item model implementation - i have a class that inherits from QAbstractListModel and overrides
Qt::ItemFlags flags( const QModelIndex & index )QVariant data( const QModelIndex & index, int role )bool setData( const QModelIndex & index, const QVariant & value, int role )QMimeData * mimeData( const QModelIndexList & indexes )- ... and more ...
In these functions named above, do i have to check if the model indexes are valid, or can i count with the framework always supplying me valid ones? I haven't seen this being specified anywhere in the documentation.

Most code does/should check. If you look at the base implementations inQAbstractListModelI think you will see they do checkisValid()? Or at least all derived classes? Since you are overriding them, or doing your own stuff before you call them, I would check. It's only anif. Or at least check if compiling for debug?
