Unsolved PDF with QWebView

[LucaLimido]

Hi
I need to display a PDF in a QWebView. I already tried various solutions proposed in other topic but i could not make them work.

This is my code:

QString strUrl = QString("file:///C:/pdf/pdf-test.pdf");
QUrl xUrl (strUrl);

QWebSettings * pxWebSettings = QWebSettings::globalSettings();
pxWebSettings->setAttribute(QWebSettings::PluginsEnabled, true);
pxWebSettings->setAttribute(QWebSettings::JavascriptEnabled, true);
pxWebSettings->setAttribute(QWebSettings::LocalContentCanAccessFileUrls, true);

m_pxRfmView->setUrl(xUrl);
m_pxRfmView->show();

N.B. m_pxRfmView is my QWebView and i user qt 5.3

I create QTWEBKIT_PLUGIN_PATH and MOZ_PLUGIN_PATH environmental variables with "C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\Browser".
I create MY_APP/plugins folder and i put in nppdf32.dll (is the same dll that is presnet into "Acrobat Reader DC\Reader\Browser" directory.

I alo tried with QPrinter but doesn't work.

can someone help me?
Thanks in advanced!

@LucaLimido
one idea to also explicitly set the mime-type:

m_pxRfmView->setContent(pdfFiledata, "application/pdf");

This has the disadvantage to load the whole PDF file into memory first. (Which is no problem for smaller sized PDF files.)

@raven-worx Thank you for reply.
I tried your solution but in my case doesn't work.
With my code or with your solution i see only the background (dark grey) . it seems that QWebView load the pdf file but it can't display

@LucaLimido
i would then expect a error message inside the PDF plugin?
But i don't know how the plugin behaves in such case.

One last try using HTML:

<object src="http://link.to/your.pdf" width="800" height="600" type='application/pdf'>
<!---Fallback--->
Can't display PDF file
</object>

@raven-worx said:
No error message.

Even with html doesn't works.

@Gaurav-Badgujar At least a "Please" would be nice - we are not in army here and people do it in their own time for free.
