Those are links to use with the git clone command.

[walter-j]

please be patient with me im new in Qt. i have typed git clone git://code.qt.io/qt/qtftp.git. i have this message checking connectivity....done. what can i do else?

[SGaist]

This has nothing to do with Qt.

Didn't you get a new folder named qtftp ?

[walter-j]

yes . will i build it in Qt?

[SGaist]

Open the project .pro file with Qt Creator and build it.

By the way, what OS are you on ?

[walter-j]

linux mint 18 sarah

[walter-j]

i got this message : cannot create a directory / mkspecs/modules-inst when im building it

[SGaist]

Which version of Qt are you using to build that module ?

[walter-j]

Qt 5.7.1 . now i can build . what can i do else?

[walter-j]

my programm does not recognize QFtp but i have already built it

[SGaist]

Did you install the module ?

[walter-j]

yes i have installed the module

[SGaist]

Did you add QT += ftp to your .pro file and re-run qmake after that ?

[walter-j]

yes.

But commandFinshed signal does not work. here is my code:

FtpDialog.h

#ifndef FTPDIALOG_H
#define FTPDIALOG_H

#include <QDialog>
#include <QFtp>
#include <QMessageBox>
#include <QDebug>

namespace Ui {
class FtpDialog;
}

class FtpDialog : public QDialog
{
Q_OBJECT

public:
explicit FtpDialog(QWidget *parent = 0);
~FtpDialog();

public slots:
void connectClicked();
void ftpFinished(int, bool);
void getFileList();
signals:

private:
Ui::FtpDialog *ui;
QFtp ftp;
};

#endif // FTPDIALOG_H

[walter-j]

FtpDialog.cpp

#include "ftpdialog.h"
#include "ui_ftpdialog.h"

FtpDialog::FtpDialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::FtpDialog)
{
ui->setupUi(this);
connect(ui->connectButton, SIGNAL(clicked()), this, SLOT(connectClicked()));
connect(&ftp,SIGNAL(commandFinished(int,bool)), this, SLOT(ftpFinished(int,bool)));

ui->disconnectButton->setEnabled(false);
ui->cdButton->setEnabled(false);
ui->upButton->setEnabled(false);
ui->getButton->setEnabled(false);

}

FtpDialog::~FtpDialog()
{
delete ui;
}

void FtpDialog::connectClicked()
{
ui->connectButton->setEnabled(false);

 ftp.connectToHost("ftp.trolltech.com");
 ui->statusLabel->setText(tr("Connecting to host..."));

}

void FtpDialog::ftpFinished(int request, bool error)
{
// Handle errors depending on the command caussing it
qDebug()<<ftp.currentCommand();
if(error)
{
switch(ftp.currentCommand())
{
case QFtp::ConnectToHost:
QMessageBox::warning(this, tr("Error"), tr("Failed to connect to host."));
ui->connectButton->setEnabled(true);

        break;
    case QFtp::Login:
        QMessageBox::warning(this, tr("Error"), tr("Failed to login."));
        ui->connectButton->setEnabled(true);

        break;

    case QFtp::List:
        QMessageBox::warning(this, tr("Error"),
                             tr("Failed to get file list.\nClosing connection"));
        ftp.close();

        break;

    }

    ui->statusLabel->setText(tr("Ready."));

}
// React to the current command and issue
// more commands or update the user interface
else
{
switch(ftp.currentCommand())
{
case QFtp::ConnectToHost:
ftp.login();

        break;
    case QFtp::Login:
        getFileList();

        break;

    case QFtp::Close:
        ui->connectButton->setEnabled(true);
       // getFileList();

        break;
    case QFtp::List:
        ui->disconnectButton->setEnabled(true);
        ui->upButton->setEnabled(true);
        ui->statusLabel->setText(tr("Ready."));

        break;

    }
}

}

void FtpDialog::getFileList()
{

}

@walter-j You should connect a slot to http://doc.qt.io/qt-4.8/qftp.html#stateChanged and see what happens

[walter-j]

But in the book they used commandFinished(int, bool) signal.

[J.Hilk]

@walter-j

keep in mind that QFftp has not been updated for a very long time and therefore may not automatically support your target FTp-Servers protocolls.

I run into this, when one of my old projects worked fine with the old FTP-Server but failed completely with the new one.

[jsulm]

@walter-j I did not say you should not use commandFinished, just add another slot to see whether you get any state changes.
