Description Nate Graham 2019-08-06 21:08:24 UTC 
The Elisa music player is using QML sliders for the playback position and volume level controls. The default qqc2-desktop-style slider appearance colors the area left of the handle with a color from the color scheme--which is blue by default with the Breeze color scheme.

In Elisa, this large blue area is distracting and not useful, so we've created a custom style to work around that (https://cgit.kde.org/elisa.git/tree/src/qml/MediaPlayerControl.qml#n194). Unfortunately, this has required a lot of custom code that is not ideal and we'd like to be more upstream-friendly.

It would be nice if there was a way to pass a standard slider a color and have it use that color for the area left of the handle instead of the color scheme color. This would allow us to customize just that visual aspect of the slider and not re-implement the whole thing from scratch.

I was unsure if Qt or the desktop style was the correct place to implement this, so please let me know if this isn't right.

Wrap it in a colorscope change the relevant colour? 

Our style should then follow it.


See

Slider.qml
    @DISABLE_UNDER_QQC2_2_4@ palette: Kirigami.Theme.palette

and 

KQuickStyleItem::resolvePalette()

Isn't ColorScope a Plasma component though? How would you do that for a pure QQC2 Slider?
