Migrating Settings from Qt5 to Qt6

[raulgd]

I have this widgets based codebase I need to migrate to Qt6, where they set default settings for QtWebEngineWidgets web engine that looks like this (because it's a web app embedded in a Qt resource file that has to load locally):

//allow loading local files (file:// URLs) from embedded chromium
    char ARG_DISABLE_WEB_SECURITY[] = "--disable-web-security";
    int newArgc = argc+1+1;
    char** newArgv = new char*[static_cast<size_t>(newArgc)];
    for(int i=0; i<argc; i++) {
        newArgv[i] = argv[i];
    }
    newArgv[argc] = ARG_DISABLE_WEB_SECURITY;
    newArgv[argc+1] = nullptr;

    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QApplication a(argc, argv);

    QWebEngineSettings::defaultSettings()->setAttribute(QWebEngineSettings::LocalContentCanAccessFileUrls, true);
    QWebEngineSettings::defaultSettings()->setAttribute(QWebEngineSettings::LocalContentCanAccessRemoteUrls, true);
    QWebEngineSettings::defaultSettings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
    QWebEngineSettings::defaultSettings()->setAttribute(QWebEngineSettings::DnsPrefetchEnabled, true);

Problem is defaultSettings() is gone, and I don't see a straight path in the documentation to use another class/function to replace it.

Please help, any suggestions are welcome!

Try:
QWebEngineProfile* profile=QWebEngineProfile::defaultProfile();
QWebEngineSettings *defaultSettings = profile->settings();

thanks for the reply @mpergand
Does that mean that on the new API, there's no way to set it as a static method so it's global for all pages and I'll have to set the profile and use it as a global variable instead of just configuring defaults at class level?

EDIT: never mind, fixed it using something like this from your suggestion, thanks!

QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessFileUrls, true);
