what would make more sense?

[jajdoo]

a rather general question, i hope it isn't too unrelated..
i have a class derived from QObject - i want to know when a dynamic property changes, so i added a signal

void   dynamicPropertyChanged  ( QByteArray name );

void   dynamicPropertyChanged  ( QByteArray name );

To copy to clipboard, switch view to plain text mode 

that i emit whenever a dynamic property changed event is caught (mainly to inform client objects):

bool polly::Element::event(QEvent *e)
{
    if( e->type() == QEvent::DynamicPropertyChange )
    {
        e->accept();
        emit dynamicPropertyChanged( static_cast<QDynamicPropertyChangeEvent*>(e)->propertyName() );
    }
    return true;
}

bool polly::Element::event(QEvent *e)
{
    if( e->type() == QEvent::DynamicPropertyChange )
    {
        e->accept();
        emit dynamicPropertyChanged( static_cast<QDynamicPropertyChangeEvent*>(e)->propertyName() );
    }
    return true;
}

To copy to clipboard, switch view to plain text mode 

now, i have a class derived from the class that emits this signal, where i want to test the property to make sure its of the appropriate type/value.
my question is: should i do it by:
- overloading event in the derived class and respond there
- create a slot that tests the new value and connect it to the signal
?
