Interface JCTreeIconRenderer

All Known Implementing Classes:

DefaultTreeIconRenderer

public interface JCTreeIconRenderer

Interface that represents a class that renders a tree icon. Although not a renderer in the strict definition of the word, this interface provides the icon to be rendered. It is not necessary to make this interface do the rendering since Icons know how to render themselves.

A default implementation of this class simply returns the plaf icon passed in.

The purpose of this mechanism is to allow a user to override the icons being drawn in a tree without a) having to figure out the plaf for the icons that they do not wish to override and b) overidding simple datatype editors.

Method Summary

Icon	getNodeIcon(TreeModel treemodel, Object node, Object value, Class object_class, boolean is_leaf, boolean is_expanded, Icon plaf_icon) Returns the icon to render to the right of the specified value.
