Convert Qt4.8 to Qt5.3 Project - QAbstractItemModel

Ferdl

Hi,

I'm using sqlite database and generate some table models for qml. This is working fine with qt4.8.
No i have converted the qt4 project to qt5.3 and the

void setRoleNames(const QHash<int, QByteArray> & roleNames)

is not longer available.

How is the best way to use new "roleNames()" function?

// current qt4.8
void database_model::generate_role_names()
{
    QHash<int, QByteArray> role_names;
    for(int i = 0; i < record().count(); ++i)
    {
        role_names[Qt::UserRole + i + 1] = record().fieldName(i).toLatin1(); // obsolete Qt5 .toAscii()
    }
    setRoleNames(role_names); // obsolete Qt5    
}

Any ideas?

Thank you

Hi,
the docu says you should use the virtual function
QHash<int, QByteArray> QAbstractItemModel::roleNames() const
instead.

Hi,

i tried this and it seems to work correct...

QHash<int, QByteArray> database_model::roleNames() const
{
    QHash<int, QByteArray> role_names;
    for(int i = 0; i < record().count(); ++i)
    {
        role_names[Qt::UserRole + i + 1] = record().fieldName(i).toLatin1();
    }
    return role_names;
}

    protected:
        QHash<int, QByteArray> roleNames() const;

Any ideas or comments or any better solution?

Thanks
Ferdl

Hi,

AFAIK, that's the correct way to do it.
