Answer 1

If you have a data model based on QAbstractItemModel which has to columns 'id' and 'name', you can do this:

enum Columns
{
    COL_ID,
    COL_NAME
}

QComboBox *combo = new QComboBox;
combo->setModel(model);
combo->setModelColumn(COL_NAME)

If you want to add items to a combobox one by one, you do this:

QComboBox *combo = new QComboBox;
combo->addItem(name, id);

Then you can retrieve id value from combobox item using:

QString id = combo->itemData(index, Qt::UserRole).toString();
