​Kevin,​

Great stuff, exactly what i was looking for.

​'strace' reveals no default search for .qss files (at least in
'kdialog').  ​
​So, is there a way to create a user stylesheet that all Qt apps will
reference?   One that can be obtained via Environment Variable or perhaps
an entry (or several) in Trolltech.conf?
( adding a key "style=windows" to the INI group "[Qt]" in Trolltech.conf
will do the same (i think) as setting your KDE default Qt Widget style, but
it'd be nice to have a stylesheet key, which i can't find reference for)

    QT_STYLE_OVERRIDE="windows" kdialog --msgbox "$(lsblk)"
doesn't seem to work, so maybe that's a Qt5 only thing  (kdialog --style
"windows", however, does work as expected)


If so, one could create a "userStyle.qss" that had stuff like:​

​
KDialog > QWidget > QLabel {
    font-family: monospace;
    font-size: 16;
    background-color: rgb(40,40,40);
    color:rgb(220,220,220);
}

​which, theoretically should only apply to KDialog (executable, or i think
there's an API?)
(unfortunately, the labels in KDialog don't have class/id AFAICT, so you
hit all of them)

But having one place to tweak styles would be useful.

I suppose this is getting low-level enough that reliance from one release
to another might get "iffy".

thanks,
