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).
Answer
First , make sure that resource file is compiled correctly on compile folder (a .RCC file or a qrc_<Resource name>.cpp)
Second, make sure your file path is correct (in my case qrc:/images/resource/html/test.html). You can open QRC file and right-click on html file and then click on Copy Resource Path to Clipboard.
Third, Note that some urls needs more time for loading completely.
Finally, I test this scenario and it works very well (Using Qt 5.1.0)
