Re: Kinetic scrolling: isn't deceleration too strong?

 

We can change values per app (I have a branch for unity that will get reviewed soon), but globally is not possible. Proper solution must be done inside qt itself... there is no workaround we can do in our sdk unfortunately.

I think the *maximum* scroll velocity value should be increased from current - if you do a fast/long swipe gesture, the scroll speed should be faster than it currently is. Compare the scrolling speed of a listview on a quick swipe on Android to ours, and you see what I mean.

There was a bug raised for this that seemed to link this issue to the max velocity being defined in pixels instead of a resolution independent unit - not sure if MP was ever approved?

I am not sure what the max value should be, but I feel the max speed should be at least double what it currently is.

Florian?

    Yeah, I agree also the addressbook is quite slow, even if it's better,
    but still not what I'm expecting from a such list.

    Not sure if that's the case (jumping is fast, but I guess that is
    definitely another story), but probably for very fast scroll actions
    showing "fake content" (until the speed is at a level where the
    user can
    really see the content) might help in this.
