Hi all,
in plasma-desktop we have this wonderful class called KRDB which syncs
Plasma settings to various other toolkits, including "KDE4".
Since it is not a library but just compiled into half the KCMs, changing
it always requires a tonne of CMake adjustments all over the place. More
importantly, though, it seems to be mostly ancient stuff and potentially
broken in recent config changes we did.
Since we just dropped Breeze Qt4 I suggest we get rid of KRDB for Plasma
5.19, too. Let's go through what KRDB does (with no claim for completeness):
= GTK 1 =
Does anybody still use this, even? Can probably go?
= GTK 2 =
From what I can tell it writes multiple colors. A GTK colors definition
which I was told isn't really honored by most styles anyway (most are
pixmap-based these days). Then it also writes a CSS for e.g. Breeze GTK
to use.
I suggest we move whatever is salvageable to our new GTK settings sync
KDED module in kde-gtk-config and nuke the rest. This way we also only
have one place messing with GTK settings. (There is still
gmenu-dbusmenu-proxy also messing with gtkrc and I'd like that part also
moved to kde-gtk-config)
= Qt =
This is for applications not using the plasma-integration QPT, e.g.
statically compiled proprietary stuff. I haven't tried it for myself but
it appears Qt these days reads kdeglobals for settings and colors [1]. I
recall the "proper" KDE theme being a rather recent addition, so maybe
we can't remove it just yet?
= KDE4 =
We removed Breeze KDE4 builds recently and distro feedback suggests
they've either discontinued Qt4 already or are in the process to. By the
time Plasma 5.19 comes out there will be another round of distro LTS
releases, so even ancient LibreOffice releases with KDE4 will be gone
then, hopefully.
= Xft =
Given this font stuff is a giant mess as it is, I'd prefer if the fonts
KCM and only the fonts KCM messes with it. Right now the Fonts KCM has
its own wrappers for things, then writes stuff into one file, has
someone else write that into another file, then has krdb read from that
second file into a third location. And surprisingly somewhere along the
way usually something goes wrong :)
= XResources =
So your xcalc looks nice? Possibly also read by toolkits other than Qt/GTK?
Cheers
Kai Uwe
