    Hi
    Dont be sorry. just practice reading docs. Its a must do for becoming PRO. :)
    It was not meant as lifted finger. just that u really need it :)

    The ID is just used to know what command a response belongs to.
    when command is done, it calls
    void QFtp::commandFinished(int id, bool error)

    so here the ID will be the same as the list() returns.

    so if you have issued multiple commands, that way you know what is what.

    The "const QString" is the name of a directory. but if you leave it empty, docs says it just mean
    "root"/top folder then. So if you dont need to only process a certain subfolder, i think leaving it empty is fine.

    And how I can get the content of a directory on a FTP-server as a string?

      for each file it will send event listInfo() signal so you need to connect to that and build a string yourself if you want
      that.
      void QFtp::listInfo(const QUrlInfo & i)

      so you get a QUrlInfo pr file.
      you can ask for string with
      QString QUrlInfo::name() const

      "The listInfo() signal is emitted for each directory entry found."

        I have now created a second connect method and a function "addToList()" like this:

        connect(m_ftp, SIGNAL(listInfo()), this, SLOT(addToList()));
        

        and now?

          HGi
          its :listInfo(const QUrlInfo & i)
          so syntax is not correct

          connect(m_ftp, SIGNAL(listInfo(const QUrlInfo &), this, SLOT(addToList(const QUrlInfo &));
          and change addToList so it takes that parameter.
          For each file it calls it
          and you can build your list or what you need.

            @mrjj said in QFtp list():

            @magguz

            and change addToList so it takes that parameter.

            how I can take the parameter into the addToList function?

              just change the addToList so it the real slot have a variable name.
              (not in the connect. they are always without names)

              void addToList(const QUrlInfo & file);

                I changed the addToList() to addToList(const QUrlInfo & file)
                Now I get an object named "file" for every directory entry, right?

                  yes you get an URL object for each file
                  and the (QUrlInfo) file has a function called
                  name() that returns a QString.

                    now I want to append the strings to a textEdit like this:

                    ui->textEdit->append(file.name());
                    

                    but it doesn't work

                      in what way "doesn't work" ?
                      What does it append?
                      is the addToList called ?

                        no it seems that addToList is not called. It appends nothing.

                          well check all your connects like
                          qDebug() << "status:" << connect(xxxx); // xxxx being what u have
                          and see they return true.
                          also test that it does connect to the server. check errors and such.

                            in

                            ftp->login();
                            

                            and it works. Thanks for your help!

                                  I changed the connect statements like this:

                                  connect(ftp, SIGNAL(listInfo(const QUrlInfo &)), this, SLOT(addToList(const QUrlInfo &)), Qt::UniqueConnection);
                                  

                                  I added only Qt::UniqueConnection as parameter. Now everything is fine :-)
