view
Type: nsITreeView
The view for the tree, which is the object which generates the data to be displayed. You can assign an object which implements nsITreeView to this property. Trees built from RDF or those which use treeitems directly will already have a view. Functions available in the view allow one to retrieve the data within the cells, and determine which rows are nested within others. For a complete list of view functions, see the nsITreeView interface.
