Signal do not work in derived class

[nickla]

I have such code:

class A : public QObject 
{
    Q_OBJECT
public:
    explicit A(QObject *parent = 0) : QObject(parent) 
    {
        connect(&http, SIGNAL(done(bool)), this, SLOT(httpDone(bool)));    
    }
 
    void sendRequest() 
    {
        // ...
        http.request(...);
    }
 
public slots:
    void httpDone(bool)
    {
        qDebug() << "recieved!";
    }
 
protected:
    QHttp http;    
 
};
 
class B : public A
{
    //...
    void getSomething() 
    {
        sendRequest();
    }
};
 
class C : public A
{
    //...  
    void getSomething() 
    {
        sendRequest();
    }
};
 
// and now do some stuff
B b;
C c;
b.getSomething();
c.getSomething();

class A : public QObject 
{
    Q_OBJECT
public:
    explicit A(QObject *parent = 0) : QObject(parent) 
    {
        connect(&http, SIGNAL(done(bool)), this, SLOT(httpDone(bool)));    
    }
    
    void sendRequest() 
    {
        // ...
        http.request(...);
    }
    
public slots:
    void httpDone(bool)
    {
        qDebug() << "recieved!";
    }
    
protected:
    QHttp http;    
    
};

class B : public A
{
    //...
    void getSomething() 
    {
        sendRequest();
    }
};

class C : public A
{
    //...  
    void getSomething() 
    {
        sendRequest();
    }
};

// and now do some stuff
B b;
C c;
b.getSomething();
c.getSomething();

To copy to clipboard, switch view to plain text mode 

And there is only one "recieved!" message in console from b. Why?

Added after 14 minutes:

From qDebug() << connect(..) output I see that SIGNAL connects to SLOT (return value is true).

Sorry.., it`s my fault. And that is why I have to go to sleep right now.
