I am trying to understand the QSqlRelationalTableModel and playing with an example coming with qt4 examples/sql/relationaltablemodel
I want to add some properties to this example.
There are two comboboxes one of is country and the other is city. I want to see cities only in cityComboBox belong to chosed country in countryComboBox.
How can i do and if it possible I need an example.
Thanks
