It is possible. You will want to use <a href="http://doc.trolltech.com/4.7/qnetworkaccessmanager.html" rel="nofollow">QNetworkAccessManager</a>, <a href="http://doc.trolltech.com/4.7/qnetworkrequest.html" rel="nofollow">QNetworkRequest</a>, and <a href="http://doc.trolltech.com/4.7/qnetworkreply.html" rel="nofollow">QNetworkReply</a> classes. Here's an (untested) example, but should get you started with retrieving the mime-type of a page using a HEAD request: <pre><code>class TestClass: public QObject { Q_OBJECT public: TestClass(); void run(); public slots: void ready(QNetworkReply * response); protected: QNetworkAccessManager * manager; }; TestClass::TestClass() { manager = new QNetworkAccessManager(this); this->connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(ready(QNetworkReply*))); } void TestClass::run() { QUrl url("http://www.widefido.com/"); manager->head(QNetworkRequest(url)); } void TestClass::ready(QNetworkReply * response) { QVariant contentMimeType = response->header(QNetworkRequest::ContentTypeHeader); qDebug() << contentMimeType; } </code></pre> NOTE: If the server does not send back a ContentType header, your QVariant will be invalid. So, before using contentMimeType, make sure you check if it is valid first. Then you can convert to a QString for checking against your list of valid mime-types. NOTE: QNetworkRequests are asynchronous, so you'll have to implement a signal-slot relationship for getting the value out of the QNetworkReploy. You can also have a look in <a href="http://qtnode.net/wiki/QxtSignalWaiter" rel="nofollow">QxtSignalWaiter</a> for doing it inline.

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.
