From e3ebbca5406ac02909823a07bfe6ae4db768f3da Mon Sep 17 00:00:00 2001 From: Allan Sandfeld Jensen Date: Thu, 11 Feb 2021 10:40:39 +0100 Subject: Improve QImage::fill(uint) documentation Remove paragraph about long gone methods, and rephrase it as a note on corresponding getters. At the same time document 64-bit behavior as undefined.
