Question

Im trying to create a global class so I can access it anywhere, but it’s not working, I get the error:

a storage class can only be specified for objects and functions

Does anyone know where I’m going wrong?

Here is my h file:

extern class Payments : public QObject
{
Q_OBJECT
public:
    Payments(QObject *parent = 0);
    virtual ~Payments();
    void purchase(const QString &id, const QString &sku, const QString &name, const QString &metadata);
    void getExisting(bool refresh);
    void getPrice(const QString &id, const QString &sku);

public slots:
    void purchaseResponse();
    void existingPurchasesResponse();
    void priceResponse();

signals:
    void purchaseResponseSuccess(const QString &receiptString);
    void existingPurchasesResponseSuccess(const QString &receiptsString);
    void priceResponseSuccess(const QString &price);
    void infoResponseError(int errorCode, const QString &errorText);


private:
    bb::platform::PaymentManager *paymentManager;

};

The storage-class keyword extern causes the problem. You can’t specify this for a class definition. And you don’t need it anyway: Your class definition will be accessible from anywhere (provided you #include the file it’s defined in).
