Subject: Port away from deprecated QWheelEvent::delta()
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/6496721110099785e49cb2a0381c714a0923e5fc

Port away from deprecated QWheelEvent::delta()

QWheelEvent::angleDelta() returns a QPoint instead of int, so we need to
use its y() value to get the number of steps.
