问题 I am trying to print a report from within my application, which involves both text and tables. Since QTextDocument won't be sufficient, I've decided to go with QWebEngineView and more sophisticated HTML/CSS which is not supported by the Qt rich text engine. I am able to create a PDF from the view, however I am having some general misconceptions, because at times its crashing, and also printing instead of PDF creation crashes. Here is my attempts: Approach 1: PDF creation This is the only

How to set painter of printer correctly?

由 落爺英雄遲暮 提交于 2020-08-10 19:17:37
问题 I'm printing a set of tables, each table should get its own page and could be long. The basics are working, but I don't get the footer painted. The problem is the footer will be painted in an extra document(s). According to the docs I must set the painter to the device. The device is painter, that's correct, but how do I set the painter to the correct Block? Or is it wrong to act this way? The goal is to use this document twice. 1st attempt is to print, the second a QTextDocument where I can

How to convert an HTML document containing an SVG to a PDF file in Python

由 北城以北 提交于 2020-07-22 06:20:16
问题 I need to adapt some Python code that converts HTML to PDF using QPrinter. The HTML includes some PNGs, but these now need to be replaced by SVGs. I do not really know how to do this. I naively replaced the PNGs with equivalent SVGs, but then the SVGs did not show up in the resulting PDF. To be more concrete, something like this from PyQt4.QtGui import QTextDocument, QPrinter, QApplication import sys app = QApplication(sys.argv) doc = QTextDocument() doc.setHtml(''' <html> <body> <h1>Circle<
