The Model is the application object, the View is its screen presentation, and the Controller defines the way the user interface reacts to user input.One of the common things we do with list and other sequences is applying an operation to each item and collect the result.In this document, we give a brief introduction to the model/view paradigm, outline the concepts involved, and describe the architecture of the item view system.Each of the components in the architecture is explained, and examples are given that show how to use the classes provided.QCombo Box uses the model/view framework for its popup list and to store its items.The default policy is is At Bottom but you can change this using set Insert Policy().

This is code of my model: QVariant Tx Order Model::data(const QModel Index &index, int role) const Qt:: Item Flags Tx Order Model::flags(const QModel Index &index) const bool Tx Order Model::set Data(const QModel Index &index, const QVariant &value, int role) I have disabled all updates of data in table and comment code in model set Data(). I have one column which can be edited by doubleclick - it is named "callsign". It is possible to constrain the input to an editable combobox using QValidator; see set Validator().A combobox can be populated using the insert functions, insert Item() and insert Items() for example.
