How to create QML enumeration? As we know Qt type have so many enumeration such as Qt.Key_Left. I want to create a custom enumeration like that.

@SomeClass
{
property enumeration type: SomeClass.EnumerationValue
}@

For doing that:

• create a subclass of QObject,
• add an enum declaration,
• declare it using Q_ENUM and
• register the object with qmlRegisterType
