JS Client NativeList $vscroll

[Michael Houlberg]

Phil,

The Native List creates a list that looks much like the list of emails in the Apple Mail app with a complex line item consisting of elements with different fonts.  I tried to get something similar by using a Complex Grid, but then you can’t accomplish a single evclick on it like with the Native List.

My app is running in the iOS Wrapper targeting iPads.

Here I’m filling a list and I want to move the current line to the last line in the list, but I also want it to scroll down to show that line.  If the selected line is below the viewable area, it selects the line correctly, but the scroll bar is positioned at the very top of the list so you don’t see the selected line.
