Install event filter on Aurorae Decoration to handle WheelEvents

Unfortunately QtQuick 1 does not provide a way to receive Wheel
events. But the window decoration needs to pass wheel events on
the titlebar to KWin core.

In order to process also Wheel Events in Aurorae an event
filter is installed on the widget and in case the mouse positon
is on the title bar the titlebarMouseWheelOperation is invoked.

Comment 3 vinnywright 2012-08-03 23:30:39 UTC
so how dose one fix it on KDE-4.9.00 ? Kubuntu-12.04 

Comment 4 Thomas Lübking 2012-08-03 23:33:45 UTC
a) ask distro to backport the fix
b) compile fixed version yourself
c) use another decoration until 4.9.1 is released.

There's no magic "__fix_bug_304248" key or environment variable, sorry.
