QListView drag and drop

[d_stranz]

No, you should be returning the logical AND of whatever flags there already are (QStringListModel:: flags()) with the bitwise NOT of Qt:: ItemIsDropEnabled. My original post had a logical OR, and I realized the mistake and fixed it a bit later.

return QStringListModel::flags( index ) & ~Qt::ItemIsDropEnabled;

return QStringListModel::flags( index ) & ~Qt::ItemIsDropEnabled;

To copy to clipboard, switch view to plain text mode 

Your code doesn't compile because you left out the "index" argument to the superclass call. In this case, I also left out the argument, but seriously, you have to look at what the compiler is telling you and figure out what is wrong.

Yes, you are right. However, this prevents all drop actions in the view. The solution to the problem, which can be found here, is to AND in Qt::ItemIsDropEnabled only if (index.isValid()). So now the problem is fixed.
