How to display embedded html in Qt WebView

I am trying to get the Qt WebView to display an html file that is embedded as a Qt resource, but I can't seem to get it to work. I created a new Qt Quick application and added a simple qml file:

import QtQuick 2.0
import QtWebKit 3.0

Rectangle {
    id: content
    width: 800
    height: 600
    color: "black"

    WebView {
        id: webView
        anchors.fill: parent
        url: "qrc:/res/test.html"
    }
}

I then created (using the Designer) a resource file that looks like this:

<RCC>
    <qresource prefix="/res">
        <file>test.html</file>
    </qresource>
</RCC>

and created a simple test.html file (in the same directory as the .qrc file):

<html>
<head><title>Hello</title></head>
<body>
  <h1>Hello World!</h1>
</body>
</html>

The result is just a blank white window. If I use a regular url (http://www.stackoverflow.com) in the qml file as the url it works - the page is displayed. If I use the name of an embedded image (qrc:/qt-project.org/mac/cursors/images/pluscursor.png) that image is displayed.

It looks to me as if the html file is indeed added (it is at least listed when I enumerate the embedded resources), but my understanding of the Qt resource system is limited, so I may very well have misunderstood something fundamental.

Can anyone tell me what I am doing wrong?

Update: I have verified that the behavior is the same if I attempt to tell the web view to load the url from C++ as well. I have also verified that the resource is indeed embedded - I can open and read the resource using a QResource. Also, this does not appear to be specific to Qt5: http://qt-project.org/forums/viewthread/18181 (someone having a similar problem with Qt 4.8).

Solution

Ok, here's how I ended up solving this. I ended up using a plain widget instead of a qml based interface.

I then had to read the first html page out from the resources manually and provide the base url. After that, subsequent pages and resources that are embedded as resources load fine.

Here's the code in question:

QResource res(":/html/index.html");
ui->webView->setHtml(reinterpret_cast<const char *>(res.data()), QUrl("qrc:/html/"));

where webView is a QWebView. My .qrc file looks like this:

<RCC>
    <qresource prefix="/">
        <file>html/index.html</file>
    </qresource>
</RCC>

This works in Qt 5.5.0.
