[SOLVED] Load an html file from a Qt Resource file
-
I have created a Qt Resource file with an html file. I want to load it and make it display in the standard web-browser. I use:
@QDesktopServices::openUrl(QUrl("qrc:/prefix/filename.html"));@
but it doesn't work!
Please notice that for normal URLs, (http://...) it works like a charm!
Any ideas?

Show your .qrc file, maybe you have wrong path (some typos).

This will never work.
QDesktopServices::openUrl() usually calls the operating system's default application to open the URL. As qrc is not a standard scheme, there is no application that will handle it. Additionally, Firefox, Explorer or Safari would not even know how to get the data behind the qrc file :)
You can set a custom handler, but that would be a QObject subclass within your application.
-
Not only the qrc scheme is (usually) not associated with any application, but remember that resources are compiled inside your executable. How is a 3rd party program supposed to access them?
A workaround could be copying the file from the resource to a temporary file/directory and then use QUrl::fromLocalFile + QDesktopServices::openUrl.

The resource file is automatic created from Qt Creator, so I find it difficult to have typos! ;-)

I understand... Could I just display the resource to a QTextBrowser, or something like that?

Could you kindly provide some sample code for the workaround you provide? :-)

Why not display your resource html page in a QWebView that way you get the full power of WebKit to help you.

Finally I followed a similar workaround, and solved the issue! :-)
