From d064dbf2d152302f319ed4a3afd784bb17d82ed2 Mon Sep 17 00:00:00 2001 From: Volker Hilsheimer Date: Fri, 8 Dec 2023 16:11:28 +0100 Subject: [PATCH] Unbreak wheel event handling in QChartView Reverts in practice e757445355dbb3f3001fae49bb72113d7a52173d, which removed wheel event handling in QChartView completely, and - by not even explicitly ignoring the event - broke event propagation to a parent that might want to handle the wheel event (such as a parent scrollview). Testing the reproducer from QTBUG-77403 shows that the problem stays fixed anyway, probably through the general fixes to wheel-event handling and propagation in 92df790f46b3a8b17aec2f385d6472fd3f8647f6.
