Scrollbar uses button background colour. Can the user override this (by editing a config file by hand)?

FWIW, there's a tabs tab for oxygen as well. It has a single option, for
inactive tabs, "Single" or "Plain". "Single" makes every tab stand out
individually, but it becomes very difficult to distinguish between the
active tab and all the others (the only difference being the line between
the tab and the body, it's missing for the active tab). Plain makes it
far easier to see which tab is active, since it's the only one with lines
around it that look like a tab, but conversely, all the inactive tabs
dissolve into an indistinct line, no marking between (inactive) tabs. I
prefer "plain" because I can at least tell the active tab easier that way,
but it'd be nice if the outline color for inactive tabs could be either
configured independently of the outline color for the active tab (instead
of them all being the same with "single" and inactives disappearing as
tabs entirely with "plain", or if the system automatically chose a color
between that of the active tab outline and the background, possibly with a
slider to control which one it tilted toward.
But far be it from me to decree that you have to use Oxygen! That's what
there's style options for! FWIW, altho I use Oxygen (widget) styles, I
prefer KDE2 for window decorations (I like the way the blended titlebars
work), and the professional desktop/plasma theme (off of kdelook, oxygen
is too dark and not transparent enough), so I don't feel the need to stick
with Oxygen where it doesn't fit my preferences, either.
Meanwhile, a hint for you. What Oxygen style controls for scrollbars is a
blend, so you're unlikely to see a specific color set anywhere. The
approach I'd take to sleuthing out what it's doing and where it's set is
strace -eopen kcmshell4 style |& grep WR | grep <$KDEHOME>
(in a konsole, naturally, |& is a bash pipe redirect that redirects STDERR
into the pipe also, <$KDEHOME> is substituted as appropriate, the WR grep
is for open for writing (not just reading), you likely won't get any
output until you close the module after changing something, and kcmshell4
--list gives you the list of possible kcontrol modules to open -- here
they've actually KEPT the more accurate kcontrol reference =:^).
You can then temporarily set the style to oxygen and try tweaking things,
to see what files are actually opened for writing... and take it from
FWIW, it appears for Oxygen it's using $KDEHOME/share/config/oxygenrc, so
I guess you don't have to do the above strace, but that's how I figured
out it was oxygenrc. I'll let you look inside the file and figure out the
config from there, but as I said, it appears to be a blending, and as the
setting is a toggle, I'm not sure you'll find a direct answer, unless you
"use the source, luke", which is kinda difficult if like me you don't make
any claims to knowing C++.
Meanwhile, what I ended up doing here is choosing a button color that was
different enough from the scrollbar background, to be distinctive, with or
without the colorful scrollbars option. In this case, since I generally
prefer dark backgrounds, most of my window backgrounds, etc, are dark blue
(the original color scheme is dark blue deb(ian), off of kdelook, but I've
modified it some as kde has matured and my understanding of the nuances
has matured as well), but buttons (background) are dark brown/red. The
actual chosen color for them is VERY dark, almost black, but the blending
effects lighten it somewhat, with the result ending up a definite brown
(that color would fit in well with the original brown ubuntu themes, but
the rest of the theme tends blue, so not so much overall). I had to work
at getting the chosen color dark enough, as I said, almost black, but
still with the right reddish-brown tint, so that with blending/shading it
came out the desired brown. The result is that it's dark enough that the
yellow button text color I use stands out well, plus dark enough that it
doesn't glare at me (I said I prefer dark backgrounds), but brown/red
enough that it still stands out well against the dark blue of the window
and scrollbar backgrounds.
I suppose I could post screenshots and the exported color theme somewhere,
if you're interested, tho as I said it's designed to work best with
oxygen, and is definitely a darker and more colorful theme than the light
grays that seem the most popular, for some odd reason -- they just make me
sick! <shrug> (Yes, I really do feel a bit nausious trying to use the
common light grayish color schemes. It's certainly not something I want
to be staring at for hours a day!)
