Class TreeModel

public class TreeModel extends GObject

A generic tree interface for use with TreeView widgets. Internally, the TreeStore and ListStore objects are constructed on top of TreeModels. If you were using the C version of gtk, you would be able to construct other objects like those (although I find no reason for doing so). This object provides a number of useful methods which can be used with either the TreeStore or ListStore.

For a full overview of the tree, list and table widgets, please see the TreeView description.
