Detailed Description

The QDeclarativeDomValueValueSource class represents a value source assignment value.

Warning

This function is not part of the public interface.

In QML, value sources are special value generating types that may be
assigned to properties.  Value sources inherit the QDeclarativePropertyValueSource
class.  In the example below, the "x" property is being assigned the
NumberAnimation value source.

Rectangle {
    x: NumberAnimation {
        from: 0
        to: 100
        loops: Animation.Infinite
    }
}

        from: 0
        to: 100
        loops: Animation.Infinite
    }
}

        rv.d->object = d->value->object;
        rv.d->object->addref();
    }
    return rv;
}

operator=()

QDeclarativeDomValueValueSource & QDeclarativeDomValueValueSource::operator=

(

const QDeclarativeDomValueValueSource &

other
