Unity3d plugin loading issue

I am trying to load a page designed to be loaded with unity 3d plugin with the below code.

Code:

---

QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);
    QWebView *webView = new QWebView();
    webView->page()->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
 
    webView->load(QUrl("file:///Users/user/Downloads/Empty/Empty.html"));
    webView->show();

---

Attachment 11103

The page is loaded as blank.

Getting the below errors
Cannot find executable for CFBundle 0x7f97f9f18d40 </Library/Internet Plug-Ins/Unused> (not loaded)

But unity web player.plugin is found in the /Library/Internet Plug-Ins

Kindly let me know where I am going wrong

I tried loading this page in QT/examples/webkitswidgets/browser, there too I am getting the same issue.

It uses NPAPI plugin to load the page. So at first, it was not getting loaded in chrome browser. Once I enabled NPAI (chrome://flags -> NPAPI enable), the page is loaded successfully.

Like the same, is there a way to enable NPAPI plugin explicitly in Qt. Since I have enabled plugins in my code.


Note : code in 1st post of this thread

WebKit uses NPAPI by default.

In that, the attached page doesn't get loaded.Attachment 11113
Please let me know, what should be done to load this page successfully.
