VirtualScroller.setContainer() method

Informs model about items container element. Usually not needed.

Signature:

setContainer(element: HTMLElement | null): void;

Parameters

Returns

void

Remarks

By default top/left offset between scroll container and first scrollable item is 0. In this case just VirtualScroller.setScroller() is needed. But extra element is needed when something “foreign” stands between scroll container and first scrollable item to measure distance between them. That extra element is represented as ItemsContainer on this schema:

<ScrollContainer>                |.|
     Some header                 |s|
     Another header              |c|
     <ItemsContainer>            |r|
        item 1                   [o]
        item 2                   [l]
        item 3                   [l]
        ...                      [b]
     </ItemsContainer>           |a|
     Some footer                 |r|
</ScrollContainer>               |.|

Must be called with null before killing the instance.
