TTreeView Class

TTreeView represents a window that displays a hierarchical list of items, such as the headings in a document, the entries in an index, or the files and directories on a disk.

Pascal
TTreeView = class(TCustomTreeView);
C++
class TTreeView : public TCustomTreeView;

ComCtrls

Use TTreeView to add an expanding and contracting outline to a form. Each node in a tree view control consists of a label and a number of optional bitmapped images. Each node can have a list of subnodes associated with it. By clicking on a node, the user can expand or collapse the associated list of subnodes.
