Hello, In grantlee there is a example called htmlapps, which creates a QNetworkReply subclass to render a template.
https://gitorious.org/grantlee/grantlee/source/master:examples/htmlapps/templatereply.cpp 24d711fc3ac88565a59c45fb6fb2dd1e75a7a9f2 This works with Qt 4.7, but the QWebView displays no content with Qt 4.8 (or with the Qt 5 port). The problem seems to be that in Qt 4.8, the file src/3rdparty/webkit/Source/WebCore/platform/network/qt/QtMIMETypeSniffer.cpp gained a new line: QByteArray data = m_reply->peek(m_sniffer.dataSize()); So, it calls peek() on the QNetworkReply object. Unfortunately, peek() is non-virtual and it is implemented with a call to read(). For a QIODevice subclass implementation of read(), it does not know whether the call to read should advance its read-pointer (it should not if it is actually a peek). The solution is to make peek() virtual. This should have happened for Qt 5.0, but it did not. All Qt subclasses of QIODevice seem to re-implement a private virtual for this purpose, so the issue seems to be long-known. I have pushed a patch to add pseudo-virtual slots as a workaround: https://codereview.qt-project.org/66023 Any better ideas? Should such a workaround be applied to the Qt 4.8 branch?
