VC++ Controls: The Tree Control, CTreeCtrl Example

A tree control is an object that displays a hierarchical list of items arranged as a physical tree but a little upside down. The items display in a parent-child format to show those that belong to interrelated categories, such as parent to child and child to grandchild, etc; or folder to subfolder to file. Here is an example of a tree list:

The starting item of the tree is sometimes called the root and represents the beginning of the tree. While most tree list have one root, it is not unusual to have a tree list that has many roots, as long as the tree creator judges it necessary. Here is an example:

Each item, including the root, that belongs to the tree is referred to as a node. An item that belongs to, or depends on, another can also be called a leaf.
