How to know end of page?
I'm using QPainter and QPrinter to print PDF file. Let say, I'm using drawText() to paint a very long paragraph, how to know it has reach the bottom of the page and create a new page?
QPrinter provides a pageRect() and paperRect() which you can compare against QFontMetrics of the QPainter opened on the printer instance.
I generally recommend reading the "printing with qt" tutorial of the Qt Documentation:
Note that for printing something that could be called a text document you'll probably have an easier life by using QTextDocument and maybe extending it (own layouts, inline elements, etc.). It already brings pagination of content and printing capabilities.
Thanks for the answer. I've already use QTextDocument, but have some problem when printing image file. That's why I try to use QPainter instead.
