Not scrolling in BoxLayout Y when using SwipeableContainer item inside

[DurankGts]

When I scroll and item SwipeableContainer inside a Layout BoxLayout Y the scroll doesn't work in this item.

I could found that the issue is when I use setLeadComponent inside a Scrollable Y with button. There is an efective way to listen pointer pressed in an Container without affect the Scroll event in a container List?

Could you explain me the use of this method

Container.setBlockLead(true);

what must be the behaivor?
