QTableWidget combobox

[jpn]

Plain declaration of a function is not enough. To be able to use a function you must also implement it. So add an implementation for ComboBoxDelegate constructor to your .cpp file:

ComboBoxDelegate::ComboBoxDelegate(QObject *parent)
    QItemDelegate(parent)
{
}

ComboBoxDelegate::ComboBoxDelegate(QObject *parent)
    QItemDelegate(parent)
{
}
