I'm using the source for the current Fedora 22 stable which is plasma-
desktop-5.3.1-5.fc22.src.rpm
I need to research more about XI2 but have gotten as far as seeing that the
code in plasma-desktop-5.3.1/kcms/input/mouse.cpp does nothing for the
reverseScrollDirection case.
MouseSettings::apply() (starts at line 705) the code of interest is at
line 758.
This code loops over all devices looking for a pointer device that has the
EVDEV_PROP_WHEEL property. My mouse does not have this property but it does
have a wheel that generates button 4 or button 5 depending on direction of
rotation.
So the loop ends up doing nothing at all.
At least for kmail, firefox, libreoffice and Calliga words what works is
to swap buttons 4 and 5. This does not fix konsole.
But I notice that left-handed has code to swap buttons 1 and 3 but that does
not show up in xinput get-button-map 8 output. I guess that there must be
other code expected to implement the left-right swap, is that a responsibility
of Qt?
Here is xinput output showing the world according to X11.
