TreeNode abstract class

Convenience class for deriving ITreeNode implementing objects for implementations. This class can be subclassed to quickly implement a node type without having to implement the tree building and navigational aspects of the interface. The following example shows a simple subclass: [TreeNode(ColumnCount=1)] public class MyTreeNode : TreeNode { string level; public MyTreeNode (string level) { this.level = level; } [TreeNodeValue(Column=0)] public string Level { get { return level; } set { level = value; OnChanged (); } } } The base class provides all the details and MyTreeNode uses to notify of tree related node changes.
