B4J Library [B4X] [XUI] SD XUIScrollView2D

I develop the cross-platform version of the ScrollView2D library.
XUIScrollView was developed all from scratch.
xScrollView is a wrapping of the native ScrollView but which standardizes the commands so that they can be used cross-platform.
Everyone can choose which one is best suited to their purpose

NOTE: You can use this library for personal and commercial use. Include it in your projects.. Attention, even if it is a B4XLib library, it is not allowed to decompress it, modify it, change its name or redistribute it without the permission of the author

See the example I attached to you. It is based on @Erel's suggestion

I reread the whole thread.

I really don't want to be annoying but :

With Scrollview2D, it works even when I implement a click event.

Your library is called XUIScrollView2D and the thread starts with "I develop the XUI version of the ScrollView2D library that created @Informatix."

God save me, I expected similar fundamental behavior.

Reread the whole ScrollView2D library, it will explain this topic.

They are two different libraries with different implementation. Don't be upset if I wrote you to reread, it wasn't meant to be an offense, but I got the impression you didn't notice Erel's suggestion.

I posted you an example, see if it can be useful.

Ok I'm not upset anymore.

I'll use ScrollView2D, XUIScrollView2D is not quite "out of the box" cross-platform (for my project) if I have to implement B4A libraries along with it.

Thanks for the help and quick follow-ups. Keep up the good work, I have seen a lot of your other libraries (views) and I appreciate this content a lot.

My library is not what a wrapper of native scrollview libraries might look like. You already get that by using xCustomListView which uses native views.

I wanted to create something from scratch and entirely with b4xView views. Behaviors are different. Scrolling is also not as smooth as native scrolling. I build the view from scratch.

It is not necessarily more performing than the others but has the goal of having 2D and uniform methods for the three platforms.

I'm sorry I wasn't helpful
