From 319462559f6a93f36aeb2c32e2f04896221cf90f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Morten=20Johan=20S=C3=B8rvig?= Date: Tue, 11 Aug 2020 16:03:48 +0200 Subject: Port tst_qiconhighdpi to the new QIcon::pixmap() API MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Port the high-dpi icon test to use the new pixmap() API which takes the target devicePixelRatio as an argument. This means we can run the fromTheme test at dpr = {1,2,3}, instead of at the current global devicePixelRatio only.
