How to copy a file from one directory to another with Qt3.3.3. ?

Hi,

I'm looking for a function to copy a file from a directory to another ... but this function is not located in that class.

Where could I find this function ?

Then I search a little bit and I discover a class nammed QUrlOperator, is that class could do what I want on a windows file system ? If yes how does it works ?

I code the two following slots

Code:

---

void testDialog::init()
{
	QString message;
	QUrlOperator op("c:\\user\\AFile.txt");
	QUrlInfo fi = op.info("c:\\user\\AFile.txt");
	message = "Filename = " + fi.name();
	write(message);
}
 
void testDialog::write( const QString &line )
{
	lb->insertItem(line);
	lb->setBottomItem(lb->count()-1);
}

---

... but it does not write the file name, what's wrong with my code ?

Thanks in advance.

I made some changes to my code

Code:

---

QUrlOperator *op = new QUrlOperator();
    QString src = "c:/user/AFile.txt";
    QString target = "c:/user/AFileCopied.txt";
    op->copy(src, target, false, false);
 
	QUrlInfo fi = op->info(target);
	write(fi.name());

---

The file is well copied but my url info object does not give me any info, why ?

Probably because QUrlOperator::copy is an asynchronous operation, so in the time of creating that QUrlInfo object the destination might not exist yet.

Ok ,so I must connect the finished signals to one of my slot to be sure that the operation is over.

Code:

---

void testDialog::init()
{
	targetPath = QDir::currentDirPath();
    targetFile = targetPath+"/AFile.txt";
	op = new QUrlOperator(targetPath);
 
	connect(op, SIGNAL(finished(QNetworkOperation*)), SLOT(displayInfo(QNetworkOperation* _nop)));
 
	nop = op->listChildren();
}
 
 
void testDialog::write( const QString &line )
{
	lb->insertItem(line);
	lb->setBottomItem(lb->count()-1);
}
 
 
 
 
void testDialog::displayInfo( QNetworkOperation * _nop )
{
	QUrlInfo fi = op->info(targetFile);
 
	write(fi.name());
}

---

but my slot is never called, what's wrong again ?

I don't see the code for starting the operation itself. Did you have a look at the example from Qt docs?
