The latter two, probably to fit in with the former. I think I may be missing
something because my KDE sliders work like I expect.

Very interesting. You are probably correct.
Hi,
it's backwards in a "numerical" sense, in that the numbers increase
with one slider type, but decrease with another, using the same
command.
However, UI designers don't think in numbers, but associations.
Left is generally associated with up, right with down, as we read left
to right, top to bottom. Therefore, up MUST map to left, down MUST map
to right, otherwise, non-mathematically minded people get uttely
confused.
I couldn't find anything on the web abou this.
But I asume the behaviour was thought out for
scrollbars and transfered to sliders.
With scrollbars scrolling lets say a table, the vertical scrollbar
has top = start, bottom = end. Horizontal scrollbar left = start,
right = end. Wheeling up on vertical sliders means scrolling
toward the vertical start. Wheeling up on the horizontal slider
should therefor mean scrolling to the horizontal start -> scrolling
left. But there's nothing to scroll with sliders.
They're not about
a position in space.
Today might well have been the first time I used the wheel
on common sliders, and it felt backwards!
Agreed. I can understand why Microsoft (and thus QT and GTK) chose to do it this way, but I bet audio users make MUCH
heavier use of sliders
than almost anyone else. So, an informal survey of Linux audio users is
actually pretty good data.
Fan-slider wheeling will stay as is, differing
from QT and
GTK sliders. But I doubt the folks behind the toolkits would
listen and change wheeling direction.
True, no reason to break it for people who are used to the old behavior,
and MS does do extensive usability testing. However this NEEDS to be
made configurable system-wide. This way CCRMA and AGNULA (for example)
can ship with the non-default slider behavior if their users prefer it.
