Class TreeStore

Implemented Interfaces:
TreeDragDest, TreeDragSource, TreeSortable

public class TreeStore
extends TreeModel
implements TreeSortable, TreeDragDest, TreeDragSource

The TreeStore is a Model used for storing data which will be displayed in any number of TreeView widgets. For an overview of how the tree and list objects fit together, see the TreeView description.

Data is stored within this object in DataColumns. This data is displayed in the widgets via CellRenderer's; the mapping between this data and the cell renderers of each treeview column is done in the TreeViewColumn class.
