org.openide.explorer.view
Class NodeRenderer

java.lang.Object
  org.openide.explorer.view.NodeRenderer

All Implemented Interfaces:

ListCellRenderer, TreeCellRenderer

---

public class NodeRenderer
extends Object
implements TreeCellRenderer, ListCellRenderer

Default renderer for nodes. Can paint either Nodes directly or can be used to paint objects produced by NodeTreeModel, etc.

See Also:

Node

---

Constructor Summary
NodeRenderer()           Creates default renderer.
NodeRenderer(boolean bigIcons)           Deprecated. bigIcons was only used by IconView, and not used by that anymore. NodeRenderer will automatically detect if the view it's rendering for is an instance of IconView.

 

Method Summary
Component	getListCellRendererComponent(JList list, Object value, int index, boolean sel, boolean cellHasFocus)           This is the only method defined by ListCellRenderer.
Component	getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus)           Finds the component that is capable of drawing the cell in a tree.
static NodeRenderer	sharedInstance()           Deprecated. This method no longer returns a shared instance, as it caused problems with one view setting properties (such as enabled state) on the renderer and the renderer then being used in its altered state by a different view. Views should create their own instance of NodeRenderer instead.

 

Methods inherited from class java.lang.Object
