I do not know the answer on non-visible XML.  Print as white text?

Another solution is QPrinter which works well for creating PDFs from text and images.  Unfortunately QPrinter does not exist for iOS so I spent much time implementing a native code version for iOS.

Personally I wish QPrinter PDF capability could be split out of QPrinter so that devices that have no printer support could still create PDF reports and email them.


Crap. It looks like I could have used QPdfWriter on iOS and saved me a lot of Objective-C headaches.  I replaced QPrinter with QPdfWriter and it basically seems to work except the fonts in the PDF are extremely tiny.  I may have to switch to QPdfWriter now.




QPrinter works well on Android, Linux, OS X, and Windows.


    QPrinter printer(QPrinter::ScreenResolution);

    printer.setOutputFormat(QPrinter::PdfFormat);

    printer.setOutputFileName(pdfFileName);

    printer.setPageOrientation(QPageLayout::Landscape);

I am embarassed that I had not run accross QPdfWriter before.  It sounds like I could have used it on iOS but not sure if it handles text and html to PDF.

I need to read the complete list of Qt classes.

I'm wanting to embed content data in XML so that it is query-able by external programs. As far as I can tell the QPdFWriter implementation we have is primarily for rasterization. Is there a way in Qt to include non-visible XML? Would it be a lot of work to add it if it does not exist? Unforunately, I'm more familiar with HP/GL and PCL than PDFs.

And I'll even open this up to outside of QML. Has anyone on this list ever tried it? I could generate our PDFs with Qt, then patch in via some external program the XML into the PDF. That would be acceptable, but not ideal.

Many thanks in advance.
