     * The KDCOPPropertyProxy class provides an easy way to publish Qt properties of a

     * property() and propertyNames() and also provides automatic set/get methods for
     * the properties of a QObject. That means for example if your object provides a
     * QString property called foo , then KDCOPPropertyProxy translates DCOP calls
     * "setFoo( QString )" and "QString foo()" automatically into the corresponding
     * setProperty/property calls.
