How to get database id value from QComboBox text?

[ohmyqt]

Hello all,

I have a 2 tables. One of them have the following data:

ID      Text
----------------
1        Apple
4        Banana
6        Mango
8        Rambutan
19      Durian

ID      Text
----------------
1        Apple
4        Banana
6        Mango
8        Rambutan
19      Durian

To copy to clipboard, switch view to plain text mode 

I got a QComboBox to populate with the right text using QSqlRelationalTableModel and QSqlTableModel:

QSqlRelationalTableModel *rtmodel = new QSqlRelationalTableModel();
 
// etc etc... populate database, set relations as per example on help files etc...
 
QSqlTableModel * relModel = rtmodel->relationModel(typeIndex);
ui->myComboBox->setModel(relModel);
ui->myComboBox->setModelColumn(relModel->fieldIndex("Text"));

QSqlRelationalTableModel *rtmodel = new QSqlRelationalTableModel();

// etc etc... populate database, set relations as per example on help files etc...

QSqlTableModel * relModel = rtmodel->relationModel(typeIndex);
ui->myComboBox->setModel(relModel);
ui->myComboBox->setModelColumn(relModel->fieldIndex("Text"));

To copy to clipboard, switch view to plain text mode 

The QComboBox shows the text fine, meaning I can choose the fruit I want. How do I get the selected text's ID once I've selected the text? Say, I picked Durian, how do I get myComboBox to return the value '19'?

Thanks.
