Make a UIScrollView with "Centering" like Windows Explorer file browser

[HoJo]

I'm not too experienced with NGUI yet but I don't see an easy way to do this. I'm going to have a UI which does not have a mouse cursor. A scrollview in the UI has a list of items, and you can use select previous/next to navigate it. I basically want it to operate exactly like a Windows file browser.

Gif of behaviour I want to recreate, I am pressing up/down arrows:

I don't mind doing my own tests/experimenting/writing my own code, but - time is always precious - any tips you might have to pursue this would be appreciated!

Easiest thing to do would be to not use a scroll view here. For something like this you have a fixed number of entries that fit on the screen. Say 8 rows. Keep track of which one is selected. When you press Up arrow with the top one selected, update the text of all your 8 labels "scrolling" up.
