I'm porting my application from WebKit to WebEngine (seems that one is much better for rendering angular-basad html). I faced with problem that i can't enable QtWebEngine to load local iframe, despite the fact that i've setup all possible settings that i found:
Code from mainwindow.cpp
view->page()->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessFileUrls, true);
view->page()->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessRemoteUrls, true);
view->page()->settings()->setAttribute(QWebEngineSettings::LocalStorageEnabled, true);
view->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessFileUrls, true);
view->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessRemoteUrls, true);
view->settings()->setAttribute(QWebEngineSettings::LocalStorageEnabled, true);
The easiest example is to take WebEngine-based FancyBrowser (\Examples\Qt-5.4\webenginewidgets\fancybrowser) and try to load in it local html file like this:
Index.html:
<html>
<head>
<title>Hi there</title>
</head>
<body>
This is a page
a simple page
<iframe id="some_idrame" width="0" height="0" style="border: none" src="some_iframe.html" name="target" sandbox="allow-scripts"></iframe>
</body>
</html>
some_iframe.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>La-la-la</title>
</head>
<body>
Lalala
</body>
</html>
If you setup env var QTWEBENGINE_REMOTE_DEBUGGING to some port, then you can open 127.0.0.1:port and see in console this error:
"Not allowed to load local resource".
I really have no idea how to solve this problem now... there should be some way to pass to WebEngine something like "--disable-web-security"...
Thanks for any help!

this Qt forum link help you . you should pass argument to application "--disable-web-security" https://forum.qt.io/topic/60691/not-allowed-to-load-local-resource-for-iframe-how-to-disable-web-security/4

If you need to load local resource(s) by WebEngine, then you need to pass --disable-web-security argument to QApplication, e.g.:
char ARG_DISABLE_WEB_SECURITY[] = "--disable-web-security";
int newArgc = argc+1+1;
char** newArgv = new char*[newArgc];
for(int i=0; i<argc; i++) {
newArgv[i] = argv[i];
}
newArgv[argc] = ARG_DISABLE_WEB_SECURITY;
newArgv[argc+1] = nullptr;
QApplication myApplication(newArgc, newArgv);
