Hi,
i don't know if there is a feature for QWebView, but if you use QNetworkRequest for the given URL and then check the header data of the reply you will get the information, e.g:
@void downloadFile(QUrl url)
{
...
QNetworkRequest req;
req.setUrl(url);
// Start request using a QNetworkAccessManager
mpDownloadManager->get(req);
...
}// Receiving function using:
// connect(mpDownloadManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(slot_fileDownloadFinished(QNetworkReply*)));
void slot_fileDownloadFinished(QNetworkReply* pReply)
{
QString sFiletype = reply->header(QNetworkRequest::ContentTypeHeader).toString()
...
}@sFiletype will contain something like:
"image/jpeg"Hope that might help you.

i try your solution but for the link "image":http://phfg.fulcri.it/getImageBdf.asp?idArticolo=1841986&tipo=4&larghezza=200&altezza=200&key=2f5e1bd528f15f9899e1cf039cbe2d09, the file type "is text/html; charset=us-ascii" instead of "image/jpeg"

Hi,
I will check the code when i'm at home again....
But using firefox you can check the header information on your own.
Just open the url containing the image file in firefox. Then open tools->web developer->web console and press F5 to reload the page.
Under 'network traffic' you will see a 'get' command:GET http://phfg.fulcri.it/getImageBdf.asp
You can inspect the 'request' and the 'response' data at this point by clicking on the entry.
best regards
