Description Daniel Petrov 2022-02-28 23:49:18 UTC

SUMMARY
When scrolling on the volume slider next to the progress bar, scrolling up/down changes the volume down/up instead of up/down.
**NOTE: My 'Invert scroll direction' option is disabled

STEPS TO REPRODUCE
1. Hover over the volume slider
2. Scroll up or down

OBSERVED RESULT
- When scrolling up, the volume decreases
- When scrolling down, the volume decreases
**When 'Invert scroll direction' is enabled, these behaviors are reversed.

EXPECTED RESULT
- When scrolling up, the volume should increase
- When scrolling down, the volume should decrease
[Same behavior as scrolling on the media or volume icons in the system tray]

ADDITIONAL INFORMATION

Probably this bug should be re-assigned to another product.
Sliders in Mouse and General Behavior KCMs are also affected on Arch Linux running Plasma 5.24.2 and frameworks 5.91.

Volume slider areas

I can also reproduce this. However this bug also depends on where you scroll on the volume bar:

- If you scroll exactly on the slider, it's busted.
- If you scroll on the padding above/below the volume bar, it works as expected.

I marked these areas on the attached screenshot.

There is something weird going on with these sliders, yeah. Will investigate.

Fix volume and duration slider mouse wheel events

Moved the MouseArea to inside the slider. Previously the Slider was
overriding the MouseArea and wheel events were not working correctly.
