Attaching signals and slots to an object within a QSharedPointer

Question

My application contained several functions like this:

void SomeClass::set_data_provider(DataProvider *data_provider)
{
    connect(data_provider, SIGNAL(data_ava         


        

Answer 1

You can create a custom connect function:

template bool
my_connect(const QSharedPointer &sender,
           const char *signal,
           const QObject *receiver,
           const char *method,
           Qt::ConnectionType type = Qt::AutoConnection)
{
    return QObject::connect(sender.data(), signal, receiver, method, type);
}

And use it like this:

QSharedPointer shared(new MyObject);
my_connect(shared, SIGNAL(my_signal()), this, SLOT(my_slot()));

The only problem is that in both yours and mine solutions you will lose Qt Creator autocomplete for the native connect function.

P.S. As for me, I wouldn't change your code. I think it's fine :)
