Qt Quarterly mistake

Hi,

I was going through this example and I think there is a mistake. Can some one please confirm this?

In the class RateController a QTimer object called stopWatch is declared. But in the function transfer() it is used to find the elapsed time. Shouldn't this object be "QTime stopWatch" ?

Thanks for your time.

Looks that you're right.

In Qt Quarterly no. 8:

In Signal Multiplexer

There is a slight typo.

Code:

---

class DocumentObject
    {
    public:
        virtual  DocumentObject() {}
        virtual void emitAllSignals() = 0;
    };

---

I think they mean a virtual destructor. '~' is missing in virtual DocumentObject() {}
