ListModel with CheckStateRole but don't show checkboxes in QComboBox

[ChrisW67]

No, i don't want to go that far.

You don't want to trivially address the problem and would rather duplicate data? Curious, but each to their own.


Here is what you are avoiding:

class CheckStateFilterProxy: public QSortFilterProxyModel                                                            
{                                                                                                                    
    Q_OBJECT                                                                                                         
public:                                                                                                              
    CheckStateFilterProxy(QObject * parent = 0):                                                                     
        QSortFilterProxyModel(parent)
    { }
 
    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const
    {
        if (role == Qt::CheckStateRole)
            return QVariant();
        return QSortFilterProxyModel::data(index, role);
    }
};

class CheckStateFilterProxy: public QSortFilterProxyModel                                                            
{                                                                                                                    
    Q_OBJECT                                                                                                         
public:                                                                                                              
    CheckStateFilterProxy(QObject * parent = 0):                                                                     
        QSortFilterProxyModel(parent)
    { }

    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const
    {
        if (role == Qt::CheckStateRole)
            return QVariant();
        return QSortFilterProxyModel::data(index, role);
    }
};
