QtNetwork and QHttp->Problem with reading the response header

[aMan]

Hi..
I have a problem related to a get request in QHttp. I never programmed anything that has to do with network (only PHP and HTML, but that doesn't count), so I'm completely new on this topic..

I'm trying to send a get request to the local apacha and then read the response code. The server gets the request and the html file gets saved to downloaded_file.txt. So that's working.
But I want to know the status code of the server, and that's not working.

Here is the code:

header file

class NetWorkTest : public QWidget
{
	Q_OBJECT
public:
	NetWorkTest(QWidget *parent = 0);
	~NetWorkTest();
 
protected slots:
	void sendHttpRequest();
	void act_requestStarted(int p_requestId);
	void act_requestFinished(int p_requestId, bool p_er);
	void act_readResponseHeader(const QHttpResponseHeader& p_resp);
 
protected:
	QLayout* m_layout;
	QHttp* m_http;
	QFile* m_file;
 
	bool m_httpRequestAborted;
	int m_httpGetID;
};

class NetWorkTest : public QWidget
{
	Q_OBJECT
public:
	NetWorkTest(QWidget *parent = 0);
	~NetWorkTest();

protected slots:
	void sendHttpRequest();
	void act_requestStarted(int p_requestId);
	void act_requestFinished(int p_requestId, bool p_er);
	void act_readResponseHeader(const QHttpResponseHeader& p_resp);

protected:
	QLayout* m_layout;
	QHttp* m_http;
	QFile* m_file;
	
	bool m_httpRequestAborted;
	int m_httpGetID;
};

I've also appended the source, in case you want something to compile..

In your code responseHeaderReceived() signal is connected to act_requestFinished() slot, not to act_readResponseHeader() slot. act_readResponseHeader() is never called.

God, such a stupid mistake..
I've checked the parameter of the response slot a hundred times, but never the name..

But it works now..
Thank you..
