Title: Detect which grid cell is active (centered on) when inside UIScrollView
Post by: par on February 28, 2014, 08:11:50 PM

This is probably an easy answer but I've been wasting my time trying to figure it out and hope that someone here can enlighten me.

I have a simple UIScrollView with a simple UIGrid inside it.  Inside the UIGrid I have 5 UIWidgets with UIDragScrollView and UICenterOnClick added to them.

Everything works perfectly.  With that said, I need to know when one of the 5 UIWidgets is "centered" on when its finished "centering" in the scroll view.  Is there a callback anywhere that accomplishes this easily?

Thanks!

UICenterOnChild has this functionality, and you can rip the code from it if you don't want it to actually do the centering.

Alright thanks!  I ended up snagging the code for UICenterOnClick and overriding the OnClick to do what I want along with calling what it calls by default.

Thanks much!
