Download a directory with QFtp

Question

I want to download all the files of a directory in the server. So, I do:

_ftp->list("myDirectory/");

I connect the signal listInfo, and I implemented the slot like this:

void manageFTP::on_listInfo(QUrlInfo info) 
{
    if (!info.isDir())
    {
        QString remoteFile= "remote";
        QFile *file = new QFile(info.name());
        if (file ->open(QIODevice::ReadWrite))
            _ftp->get(remoteFile, file);
    }
}

My problem is to know when the download is entirely finished because I don't know how many files are in the directory and I don't know the id of the last get. How can I know and be sure the download has finished?

Answer 1

Your LIST and GET commands are scheduled and performed asynchronously. When the last pending command has finished QFtp emits a done(bool error) signal. So just connect a suitable slot to this signal before you execute the LIST command and you will be notified when all your commands have finished. Don't forget to disconnect the signal when done.
