Does anyone know of a way to get the current scroll bar position of a QNX List? The scrollBarOffset is the physical position of the scroll bar in the list not the scrolled amount. I am trying to place a control next to a list based on the selected item, and I am 95% there with my current approach, but the problem is that scrollIndexVisible does some funcky things when an item is selected near the bottom of the list (OK near the top). If I knew how much a list if scrolled by and the height of each cell (known), then I can accurately convert to global coordinates correctly.
You might consider making a custom list. They aren't that hard. You place as ScrollPane with a Sprite as it's "setScrollContent", where the Sprite acts as a container for your scroll stuff. Then you can use scrollX or scrollY for the scoll position.
@jtegen - did you ever resolve this? I am having similar issues on BB10. I need to reset the scroll position on the QNX list after an update is made to the data provider of the list. The scrollToIndex() with an animation time of 0 doesnt always work properly.

ScrollPane is not available in BB10 SDK, but the approach does generally work in a scrolled container. I agree that it is not 100% consistent. If you can get it to repeat, it would be worth a bug report to get it fixed. I moved onto a different approach since this just did not work well.
