ABSTRACT:
A tree view control is provided as a system resource that may be used by application programs. The tree view control enables an application program to display a hierarchical list of items. The hierarchical list of items may be expandable or collapsible so as to vary the view of the hierarchical tree that is visible to a user. The expansion and collapsing of the tree is performed by a mechanism that is independent of the selection mechanism that is used to select items in the hierarchical tree. An in-place editing mechanism is provided to facilitate the in place editing of labels of items in the hierarchical tree. As an optimization, the tree view control may provide for deferred evaluation of items such that the display information needed to display an item on an output device is not evaluated until needed.
