Interface ItsNatListUI

All Superinterfaces:

ItsNatComponentUI, ItsNatElementComponentUI

All Known Subinterfaces:

ItsNatHTMLSelectUI

public interface ItsNatListUI
extends ItsNatElementComponentUI

Is the base interface of the User Interface of a list component.

List items are managed as a DOM element list, using the current list structure and renderer.

Current implementation does not use the data model and relays heavily on ElementList.

Indexes are 0 based.

Returns an object info of the child element at the specified position.

Parameters:

index - index of the element to search for.

Returns:

the object info of the matched child element. Null if index is out of range. This object is ever the same per list item and may be used to save any context data.

Returns an object info of the child element containing the specified node (or the node is itself an element of the list).

Parameters:

node - the node to search for.

Returns:

the object info of the matched child element. Null if this node is not contained by the list. This object is ever the same per list item and may be used to save any context data.
