Interface TreeIcons

All Known Implementing Classes:

DefaultTreeIcons

public interface TreeIcons

This interface is called by the Tree rendering code to retrieve named icon images. These icons are sued to provide visuals such as the lines between tree nodes and expnasion handles. The TreeIcons interface can be used by TreeCellRenderer objects to obtain default icons for "parent" and "leaf" nodes in the Tree.

The tree will ask for nodes with the following names :

ICON_PLUS - the expanding + for normal nodes with children
ICON_PLUSBOTTOM - the expanding + for the last node of a parent node
ICON_MINUS - the contracting - for normal nodes with children
ICON_MINUSBOTTOM - the contracting - for the last node of a parent node
ICON_FOLDER - a folder icon for closed nodes with children
ICON_FOLDEROPEN - a folder icon for opened nodes with children
ICON_JOIN - a joiner line icon for a normal nodes
ICON_JOINEBOTTOM - a joiner line icon for the last node of a parent node
ICON_JOINENOLINE - a joiner icon for normal nodes when no lines awre required
ICON_LEAF - a leaf icon for nodes with no children
ICON_LINE - a line icon between nodes
ICON_EMPTY - a empty icon between nodes
ICON_ROOT - a root icon
ICON_ROOTOPEN - a root open icon
