Signal QWebEnginePage::loadFinished has a bool ok parameter and signal QWebEnginePage::pdfPrintingFinished has a bool success parameter that indicate if there was an error. But both signals don't have any additional error information. Is there a way to get detailed error information about HTML parsing and PDF creation?
I want to convert a self generated HTLM document to a PDF with a QWebEnginePage. Sometime it works, but sometimes loadFinished has ok = false and the web page is empty. When I save the HTML, Chrome can load it without problems.
PDF generation can always fail for a variety of file system issues and I want to give the user hints how to fix these issues.
I faced the same issue recently, which might be due to the fact that there is a 2 MB limit described here.
I was able to finally display the HTML page, loading it from a temporary/transitory file where I dumped the HTML string. But I did not find a way to save such big HTML pages as PDF. Note that when I tried to display this HTML page on Chrome (which is based on Chromium, that Qt is using if I'm right), I also had an error when trying to export it as a PDF.
