    Description

      ComboBox already has a textRole, to simplify user code when dealing with a model having multiple roles, ComboBox should also have a valueRole.

      We could add these properties and function:

      • writable valueRole : similar to textRole
      • readonly currentValue: similar to currentText
      • findValue function: similar to the find function

      Usage could then be:

      ComboBox {
    model: [ {value: SomeEnum.One, text: "One"}, {value: SomeEnum.Two, text: "Two"}]
    textRole: "text"
    valueRole: "value"
    currentIndex: findValue(someBusinessObject.value)
    onActivated: someBusinessObject.value = currentValue
}
