Description
The Depth property specifies the structure of the items in a TreeView object. It is either a scalar 0 or an integer vector of the same length as the Items property.
A value of 0 indicates that the corresponding item is a top-level item. A value of 1 indicates that the corresponding item is a child of the most recent item whose Depth is 0; a value of 2 indicates that the corresponding item is a child of the most recent item whose Depth is 1, and so forth.
For example:
