Detailed Description

This class provides an interface for synchronous downloads. It currently relies on QNetworkAccessManager and thus on the existence of a QCoreApplication object. If no global instance is existing a local application object is created. For this reason you must not use this class in any thread but the main thread if you did not create a QCoreApplication object yourself.

REMARK: this class is considered experimental and its interface can be a subject to redesign.
