From 6629d046b713e27a85ce2ba69b436629ddcf9804 Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Tue, 24 Mar 2020 15:02:17 -0700 Subject: mobile/profile: adjust offsets when scaling If the user is scaling out again we need to make sure that our offsets are adjusted so that we always show a subset of the profile and not 'empty space' outside of it. Instead of reimplementing the offset logic, let's just trigger another paint() call. This requires a trampoline function because of different signal and slot signatures.
