Will Qt 5.6 have alternative methods to export HTML to PDF that support major platforms of Android, iOS, Linux, OS X, and Windows?

On iOS a Qt developer must resort to native code to generate PDF files.

Unfortunately Qt 5.5 PDF export is dependent on QPrinter which is not supported on iOS.  While iOS can create and displays PDF’s just fine, iOS has no printer support.


In the future, Is it possible the PDF creation dependency could be separated from QPrinter?  So that Qt PDF generation would have better cross-platform support?


    QPrinter printer(QPrinter::ScreenResolution); // QPrinter not supported on iOS

    printer.setOutputFormat(QPrinter::PdfFormat);

    printer.setOutputFileName(pdfFileName);

    drawReport(printer);

    m_painter.end();


Without understanding internals of PDF file creation, it feels like PDF creation should not be dependent on QPrinter?

We have an alternative to using QPrinter since Qt 5.0. Please have a look at QPdfWriter. It's in Qt Gui, fully platform independent and should just work on iOS.

Cheers,
Lars

Thanks for all the feedback everyone.

We are excited about the 5.6 release because we are looking closely at the new Qt3D module, as well as migrating to VS 2015.  Sadly, PDF export of HTML content is a critical feature for our product (in general I’m happy to move to WebEngine, but we cannot remove output functionality from our software).

Building from source would be an option, I guess.  We have done it in the past, but the build process / flags (for distribution) is not sufficiently well documented, and starting with 5.5.1 we were excited to be able to use official binaries.

Kind regards,
Mark

Hi Mark,

If you need to use Qt Webkit, then it is probably better to stay with Qt 5.5. There is nothing that makes Qt 5.5 bad overnight, if it works for you now. Qt WebEngine is in many aspects already much better in features than Qt Webkit. Qt WebEngine is also better maintained, and does receive much more improvements and security fixes than Qt Webkit. Even though some features of Qt WebKit are not in same way available with Qt WebEngine, it is overall a better choice. Qt Webkit is removed from Qt 5.6 because it is no longer maintained well enough to be part of an official Qt release. We are also not developing and testing it to work with Qt 5.6.

Yours,

                          Tuukka

Hi all,

QtWebEngine does not yet have feature parity with QtWebkit.  For instance, print support (especially export to PDF) is a critical requirement for my use of Webkit.  This missing feature prevents me from migrating to WebEngine.

Removing webkit from the official distribution will prevent me (and surely others) from upgrading to 5.6.

Thanks,
Mark
