Description

Hi,

Thank you for creating a wonderful library.
It is very helpful for me and can we add field as visibleFraction in ObserverModel?
A fraction in the range [0,...,1] that represents what proportion of the widget is visible (assuming rectangular bounding boxes).

Why

When the displayingChildModelList field represents [0, 1, 2] and the visibleFraction is aligned on each record [0.5, 0.2, 0.3]. so we can choose the best index which in this case is 0 instead of taking the first or last index in displayChildModelList.

Good idea, visibleFraction has been added to the development branch, you can try it to see if it satisfies your requirement.

Hi @LinXunFeng,

The visibleFraction field seems to be working well too.
I'll close this ticket now. Thanks so much!
