If you're implying that for a vertical volume slider then "scroll up" on a trackpad should in fact be volume up (i.e. the current behavior after this bug was fixed) *then* it stands to reason that the same should be true for a horizontal slider as, despite there being no "correct" spatial mapping due to the axis being different, the "volume up" metaphor still holds. Indeed, this same rationale applies to non-spatial cases like the Plasma system tray volume icon itself, which simply displays a varying number of "waves". In general, non-scrollbar linear widgets on desktop environments (and, indeed, largely so in the physical world) have always used the "positive right / up" convention, so it stands to reason that they would be mapped this way. That said, I just noticed that horizontal sliders and indeed the tray icon itself *also* respond to horizontal trackpad movement, which is also excellent as it matches the direction of the slider. As I said in my earlier comment, the only reason we ended up in this mess to begin with is because scroll wheels were *specifically* intended for the use case of viewport scrolling first (which is inverted vs. the content), then widgets have always tried to use "natural scrolling" by inverting the scroll direction at the widget level, and then finally "natural scrolling" for trackpads was originally implemented as a hack that inverted all scrolling regardless of scroll target, making the widgets move backwards unintentionally. People might have gotten used to that, but I really doubt there is a strong argument to be made that this behavior is, in any way, intuitive. -- You are receiving this mail because: You are watching all bug changes.
