Hi Scott,
By default, support for the Fetch API is not enabled for the QRC scheme. You
can override the defaults by adding this to your main function:
QWebEngineUrlScheme qrcScheme(QByteArrayLiteral("qrc"));
qrcScheme.setFlags(QWebEngineUrlScheme::FetchApiAllowed);
QWebEngineUrlScheme::registerScheme(qrcScheme);
Make sure to read through the
documentation<https://doc.qt.io/qt-6/qwebengineurlscheme.html#Flag-enum> for
all the different flags you can enable. Also note that this needs to be done
very early in the app’s initialization stage, before any WebEngine objects are
instantiated.
Cheers,
Kaloyan

Subject: [Development] QRC based javascript source in QWebEngineView
Im having problems loading html that has javascript inside of it.
I am loading the URL into the QWebEngineView via a url that looks like QUrl(
“qrc:/XXX.html” )
The top level html, uses a standard html tag for <script src=”xxxx”> where xxx
is always relative, there are no QRC based urls inside the html or any imported
JS files.
However, it seems that the nested import commands in the JS do not look inside
the QRC, and for some reason I get an error saying
js: Fetch API cannot load qrc:/pathtofile/base.json. URL scheme "qrc" is not
supported.
I have confirmed that the file DOES exist from the C++ QFile based world, but
Im stumped trying to figure out what is going on.
Is there anyway to track this down?
Scott
