You can try this too (this is found in Qt 3 source code, edited for 
simplicity), which confirms the rule that you can do anything in C++ with an 
extra level of indirection:

class QDnsUgleHack: public QDns {
public:
    void ugle( bool emitAnyway=FALSE );
};

void QDnsUgleHack::ugle( bool emitAnyway)
{
    if ( emitAnyway || !isWorking() ) {
        emit resultsReady();
    }
}

And in the code:
                ((QDnsUgleHack*)dns)->ugle( TRUE );

On second thought... maybe you shouldn't :-)
