Questions tagged [treenode]

The base element of a hierarchical tree-like data structure.

Trees are hierarchical data structures that represent undirected acyclic graphs. A tree is therefore composed of connected nodes.

One specific node is the root of the tree. The root node is connected to several nodes (sometimes called children), each of these being the root of a subtree, and so-on. A node of a tree that does not have any children is called a leaf. All nodes of the tree are connected directly or indirectly to the root.

Treenodes are usually recursive datastructures.

  • In .Net framework a TreeNode is a node in TreeView UI control that displays tree-like objects.
  • In Java a TreeNode is an interface that nodes of a JTree UI control that displays tree-like objects.
