SUUMARY We can adjust the volume level by scrolling on top of the sliders of plasma-pa applet. But we cannot do the same with the sliders in Audio KCM. STEPS TO REPRODUCE 1. open Audio KCM 2. hover over any slider 3. scroll up/down OBSERVED RESULT nothing happens EXPECTED RESULT volume level changes SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 Graphics Platform: Wayland
Can reproduce. Seems like an issue specific to the custom slider object in this KCM.

Pushed by fanzhuyifan into branch 'master'. kcm/VolumeSlider: fix scroll stepSize was not set to disable tickmarks. However scrolling also depends on stepSize. qqc2-desktop-stlye implements scrolling via increase()/descrease() functions, which default to steps of 0.1 when stepSize is not set. Override them to get scrolling working without setting stepSize.
