For maximum interoperability with QML, any property that is writable should have an associated NOTIFY signal that is emitted whenever the property value has changed. The CONSTANT attribute should only be used for properties whose value is set, and finalized, only in the class constructor. Even outside of GUI programming this could be useful.
