B4J Library [B4X] [XUI] SD XUIScrollView2D

[Star-Dust]

I develop the XUI version of the ScrollView2D library that created @Informatix. I did not base myself on its code but developed everything from scratch. It is still unripe, but it works well and is not very heavy. Clearly for iOS already the native ScrollView is 2D as well as for Desktop.

Thanks, Stardust. This fills a long awaited need. BUT
your example contains several controls, but when trying to add a click event it says "current module does not support layout events". Why and how to enable?
Best, john m.
