Reading file's content from ftp.

Hi.

I'm using Qt 4.4.3 and try to read file's content from ftp server and show it with QTextEdit.

Code:

---

QBuffer file;
file.open(QIODevice::ReadWrite | QIODevice::Text);
file.setObjectName(fileName);
 
ftp->setTransferMode(QFtp::Passive);
ftp->connectToHost("192.168.10.17", 21);
ftp->login();
ftp->get(fileName, &file);
 
QString lines;
QTextStream in(&file);
while (!in.atEnd())  {
    lines = in.readAll();
    textEdit->setText(lines);
}
 
file.close();
ftp->close();

---

Above code shows nothing. I mean, textEdit is empty.

Outputs from ftp server are:

Quote:

---

RETR test.diag
150 Opening data connection
Successfully sen file 'c:\ftproot\test.diag' (1112129 B sent)
226 transfer complete

---

And from my console:

Quote:

---

Command Finished! Id:1-Status:0

Connection State Changed->2 Status: Connecting
Connection State Changed->3 Status: Connected

Any ideas what am I missing here?

QFtp::get() is an asynchronous operation.

You have to wait for it to finish before you attempt reading the output buffer. See QFtp::commandFinished()

Of course, thanks!
