Parameters

Parameters	Description
Value: IJvDataItem	Item to be used as the active item or root item. Specify nil to use no item or use the entire tree.

Description

SetItem selects a new (root) item for the consumer.
For consumers that only allow a single item to be used, the new item is the item used by the consumer (specify nil if no item is to be selected).
For consumers that allow multiple items to be rendered, the new item is the item used as a root (specify nil if the entire tree is to be used). The consumer will only use items that are a child of the specified item; the item itself is not used.
