Custom Icons in JTree

Is there a way to place custom icons in a JTree to replace the standard folders and pages?
Thanks,
Jeremy

I know how to change the Leaf Icon.
myDefaultTreeCellRenderer.setLeafIcon(new ImageIcon("somefile.gif"));
Probably similar for the nodes and root.

Ok, to set the Open Folder Icon you do the same except, setOpenIcon(new ImageIcon());
and the setClosedIcon(new ImageIcon()) sets the closed folder Icon.

I'm setting everything as a DefaultMutableTreeNode. I execute a SQL statement and step through the ResultSet to add each element as a node. Then I create a tree model passing that node to the constructor. Is there a way to change the icon of a node so that I don't have to recode the tree using leafs?

You can implement a TreeRenderer and use the getTreeCellRendererComponent to specify the icon of each node.

public Component getTreeCellRendererComponent( JTree tree,
                                                 Object value,
                                                 boolean bSelected,
                                                 boolean bExpanded,
                                                 boolean bLeaf,
                                                 int iRow,
                                                 boolean bHasFocus ) {
    // Find out which node we are rendering and get its text
    DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;
    String labelText = (String)node.toString();
    // Change the color of selected items
    if(bSelected){
      setForeground(Color.black);
      setBackground(Color.white);
    }else{
      setForeground(Color.black);
      setBackground(Color.getColor("#CCCCCC"));
    }
    // Determine the correct icon to display
    if( node.isRoot())
      setIcon(RootIconImage);
    else if(bLeaf)
      setIcon(LeafIconImage);
    else
      setIcon(DefaultIconImage);
    // Add the text to the cell
    setText(labelText);
    return this;
  }
