emit Signals

what does not work ???

class CWorkThread : public QThread
{
	Q_OBJECT
 
public:
	CWorkThread(QObject *parent);
	~CWorkThread();
	void run();
 
public slots:
		void FinishProc();
 
};

class CWorkThread : public QThread
{
	Q_OBJECT

public:
	CWorkThread(QObject *parent);
	~CWorkThread();
	void run();

public slots:
		void FinishProc();

};

To copy to clipboard, switch view to plain text mode 

void CWorkThread::run()
{	
	CWorkFiles *files = new CWorkFiles;
	connect(files,SIGNAL(finished()),this,SLOT(FinishProc()));
	QApplication::beep();
	exec();
}

void CWorkThread::run()
{	
	CWorkFiles *files = new CWorkFiles;
	connect(files,SIGNAL(finished()),this,SLOT(FinishProc()));
	QApplication::beep();
	exec();
}

this block newer running !

void CWorkThread::FinishProc()
{
	QApplication::beep();
}

void CWorkThread::FinishProc()
{
	QApplication::beep();
}

--------------------------

class CWorkFiles : public QFile
{
	Q_OBJECT
 
public:
	CWorkFiles(QObject *parent = 0);
	~CWorkFiles();
 
	qint16 CopyFile(QString cSrc, QString cDst);
	qint16 MoveFile(QString cSrc, QString cDst);
	qint16 DeleteFile(QString cPath);
	qint16 IsFileExists(QString cPath);
 
signals:
	void finished();
 
};

class CWorkFiles : public QFile
{
	Q_OBJECT

public:
	CWorkFiles(QObject *parent = 0);
	~CWorkFiles();

	qint16 CopyFile(QString cSrc, QString cDst);
	qint16 MoveFile(QString cSrc, QString cDst);
	qint16 DeleteFile(QString cPath);
	qint16 IsFileExists(QString cPath);

signals:

};

qint16 CWorkFiles::CopyFile(QString cSrc, QString cDst)
{

Does CopyFiles ever gets called?

[jpn]

I don't see CWorkFiles::CopyFile() getting called anywhere.

PS. You should allocate that CWorkFiles object on stack (without new).

[Fastman]

yes, called !

CWorkFiles::CWorkFiles(QObject *parent)
	: QFile(parent)
{
	CopyFile("d:\\6.2-RELEASE-i386-docs.iso","d:\\tmn.iso");
}

CWorkFiles::CWorkFiles(QObject *parent)
	: QFile(parent)
{
	CopyFile("d:\\6.2-RELEASE-i386-docs.iso","d:\\tmn.iso");
}

To copy to clipboard, switch view to plain text mode 

and rewrite:

void CWorkThread::run()
{	
	CWorkFiles files;
	connect(&files,SIGNAL(finished()),this,SLOT(FinishProc()));
	QApplication::beep();
	exec();
}

void CWorkThread::run()
{	
	CWorkFiles files;
	connect(&files,SIGNAL(finished()),this,SLOT(FinishProc()));
	QApplication::beep();
	exec();
}

To copy to clipboard, switch view to plain text mode 

but no effect !

[marcel]

It is because you make the connection after the function is getting called, in the constructor.

Call it after you make the connection, outside the constructor, or make the connection inside the constructor.
