As described in the title my problem is that qwebview doesn't load a html file correctly if it resides in my resources. It loads it perfectly if I load it from outside of the resources as normal local file. But this is not an option for me. I would like to bundle the file with the application.
EDIT: By the way, I'm talkin' about external resources from the web. (e.g. .js) Thanks for any help

- How do you load a file from resources into QWebView? – Piotr Dobrogost Commented Feb 26, 2011 at 13:17
- @Piotr Dobrogost: I load it via the load() method. – domachine Commented Feb 26, 2011 at 17:03

Reset to default 5Please take a look at the second parameter of
void QWebView::setHtml ( const QString & html, const QUrl & baseUrl = QUrl() )
According to documentation:
External objects such as stylesheets or images referenced in the HTML document are located relative to baseUrl.
Below is code that works for me.
#include <QtCore/QFile>
#include <QtCore/QUrl>
#include <QtGui/QApplication>
#include <QtGui/QMainWindow>
#include <QtWebKit/QWebView>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QMainWindow window;
QWebView webview(&window);
QFile source(":/google..html");
source.open(QIODevice::ReadOnly);
webview.setHtml(QString::fromUtf8(source.readAll().constData()), QUrl("http://google."));
window.setCentralWidget(&webview);
window.show();
return app.exec();
}
External URLs must have a schema to make them external, otherwise "external/script.js" looks for "script.js" under the "external/" sub-path, "http://external/script.js" is an absolute URL.
Edit:
Say you have this HTML file as the resource ":/file.html" and it is coppied from "http://example./":
<html>
<head>
<title>My HTML</title>
<script type="text/javascript" src="/code.js"></scipt>
</head>
<body>
<img href="/image.jpg" />
</body>
</html>
Then to display this correctly you would need to do the following:
QFile res(":/file.html");
res.open(QIODevice::ReadOnly|QIODevice::Text);
my_webview.setHtml(res.readAll(), QUrl("http://example./");
That way, WebKit knows where to fetch "code.js" and "image.jpg" from. Using QWebView::load() will not work, as the root URL will be some internal URL, the one starting with qrc://, and WebKit will look for "code.js" and "image.jpg" in your applications resources. Basically, you can only use load() when all the relative URLs in the document e from the same place as the URL is pointing to. And if you used load(QUrl("qrc:///file.html")); in the case above, the URL (qrc:///file.html) is pointing to your resource system.
If you want to also include your resources in the HTML, you can use the qrc:// URLs in the HTML file.
