/**
    \class QtColorPropertyManager

    \brief The QtColorPropertyManager provides and manages QColor properties.

    A color property has nested \e red, \e green and \e blue
    subproperties. The top-level property's value can be retrieved
    using the value() function, and set using the setValue() slot.

    The subproperties are created by a QtIntPropertyManager object. This
    manager can be retrieved using the subIntPropertyManager() function.  In
    order to provide editing widgets for the subproperties in a
    property browser widget, this manager must be associated with an
    editor factory.

    In addition, QtColorPropertyManager provides the valueChanged() signal
    which is emitted whenever a property created by this manager
    changes.
