battery: Improve the brightness responsiveness

Authored by apol on Dec 16 2019, 1:14 AM.



Use QQC2.Slider, so that we have a moved signal. This way we can only
issue new brightnesses when the user actually interacts with it.
Don't adapt to the system brightness until we have finished interacting
with it.

Test Plan

Manual testing, flickering is very much reduced both when scrolling over the
compact plasmoid as well as the slider.

PlasmaComponents 3 Slider doesn't react to wheel events, which must be fixed before this can go in.


What about this?


Should we not forward the notion of "moved" here, too?


Wouldn't that cause subsequent calls to fail if the previous hasn't finished yet? Wouldn't that be annoying if you drag the slider quickly?

Use a more meaningful step size for the screen. Having steps of 1 in a 1 to 7000 slider was awkward.

No, it will be called eventually, which is all that matters.
