    <p>I see you're trying to use QHTTP and QHttpRequestHeader classes. QT documentation says those are deprecated:</p> <blockquote> <p>This class is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p> </blockquote> <p>so, as it was suggested before; I would recommend using <a href="http://qt.nokia.com/doc/4.6/qnetworkaccessmanager.html" rel="nofollow noreferrer">QNetworkAccessManager</a> for what you're trying to do</p> <p>as for your original question; you still can use QHTTP to upload files; I believe actual request headers structure depends on the particular site you're trying to access. In this case tools like <a href="http://www.wireshark.org/" rel="nofollow noreferrer">wireshark</a> would be in great help. Pls, check if code below would work for you, it should upload test1.jpg file from the home folder and dump its link on the server if 302 response returned.</p> <pre><code>void MainWindow::on_pushButton_clicked() { http = new QHttp(this); // http declared as a member of MainWindow class connect(http, SIGNAL(requestFinished(int,bool)), SLOT(httpRequestFinished(int, bool))); QString boundary = "---------------------------723690991551375881941828858"; // action QByteArray data(QString("--" + boundary + "\r\n").toAscii()); data += "Content-Disposition: form-data; name=\"action\"\r\n\r\n"; data += "file_upload\r\n"; // file data += QString("--" + boundary + "\r\n").toAscii(); data += "Content-Disposition: form-data; name=\"sfile\"; filename=\"test1.jpg\"\r\n"; data += "Content-Type: image/jpeg\r\n\r\n"; QFile file("/home/test1.jpg"); if (!file.open(QIODevice::ReadOnly)) return; data += file.readAll(); data += "\r\n"; // password data += QString("--" + boundary + "\r\n").toAscii(); data += "Content-Disposition: form-data; name=\"password\"\r\n\r\n"; //data += "password\r\n"; // put password if needed data += "\r\n"; // description data += QString("--" + boundary + "\r\n").toAscii(); data += "Content-Disposition: form-data; name=\"description\"\r\n\r\n"; //data += "description\r\n"; // put description if needed data += "\r\n"; // agree data += QString("--" + boundary + "\r\n").toAscii(); data += "Content-Disposition: form-data; name=\"agree\"\r\n\r\n"; data += "1\r\n"; data += QString("--" + boundary + "--\r\n").toAscii(); QHttpRequestHeader header("POST", "/cabinet/upload/"); header.setValue("Host", "data.cod.ru"); header.setValue("User-Agent", "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.9) Gecko/20100401 Ubuntu/9.10 (karmic) Firefox/3.5.9"); header.setValue("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"); header.setValue("Accept-Language", "en-us,en;q=0.5"); header.setValue("Accept-Encoding", "gzip,deflate"); header.setValue("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7"); header.setValue("Keep-Alive", "300"); header.setValue("Connection", "keep-alive"); header.setValue("Referer", "http://data.cod.ru/"); //multipart/form-data; boundary=---------------------------723690991551375881941828858 header.setValue("Content-Type", "multipart/form-data; boundary=" + boundary); header.setValue("Content-Length", QString::number(data.length())); http-&gt;setHost("data.cod.ru"); http-&gt;request(header, data); file.close(); } void MainWindow::httpRequestFinished(int, bool) { QHttpResponseHeader responce = http-&gt;lastResponse(); if (responce.statusCode()==302) { qDebug() &lt;&lt; "file accepted; get it from:"; qDebug() &lt;&lt; "data.cod.ru" &lt;&lt; responce.value("Location"); } } </code></pre> <p>httpRequestFinished declared in the signals section of the MainWindow class</p> <p>hope this helps, privet ;)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
