QListView trouble accepting drops

[jpn]

Set QDirModel::setReadOnly(false) and reimplement QDirModel::flags() to return Qt::ItemIsDropEnabled:

class AdvQDirModel: public QDirModel
{
public:
    AdvQDirModel(): QDirModel() { setReadOnly(false); } // <---
    ~AdvQDirModel() { }
 
    Qt::ItemFlags flags(const QModelIndex& index) const
    {
        Qt::ItemFlags f = QDirModel::flags(index);
        if (isDir(index))
            f |= Qt::ItemIsDropEnabled; // <---
        return f;
    }
};

class AdvQDirModel: public QDirModel
{
public:
    AdvQDirModel(): QDirModel() { setReadOnly(false); } // <---
    ~AdvQDirModel() { }

    Qt::ItemFlags flags(const QModelIndex& index) const
    {
        Qt::ItemFlags f = QDirModel::flags(index);
        if (isDir(index))
            f |= Qt::ItemIsDropEnabled; // <---
        return f;
    }
};

EDIT: Actually, now that I relook at it, all you need is to set QDirModel::setReadOnly(false) and that's all. You don't even need to reimplement flags(). The default implementation will enable dropping once read only property is set to false and the dropping target is a writable directory.

QDirModel model;
model.setReadOnly(false);
QListView listView;
...
listView.setModel(&model);

QDirModel model;
model.setReadOnly(false);
QListView listView;
...
listView.setModel(&model);
