Jtree change childs icons

Question

Hi All,
im wondering if someone try that.
i have a tree that include a parent and child/s.
when i selected the father all the child's should be selected too.
i was trying :
public void valueChanged(TreeSelectionEvent arg0) {
                    // TODO Auto-generated method stub
                    DefaultMutableTreeNode node = DefaultMutableTreeNode)tree.getLastSelectedPathComponent();
                    String s2 = (String)node.getUserObject();
                    DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();
                   renderer.setLeafIcon(SelIcon);
                   renderer.setOpenIcon(SelIcon);
                   renderer.setClosedIcon(SelIcon);
                  //CheckNodes(node,renderer);
                    renderer.setBackgroundNonSelectionColor(frameColor);
                    tree.setCellRenderer(renderer);
               }     my problem it is changed the entire tree, and i want to change specific nodes.
if someone can help ill appreciate it.

First Thanks for your answer.
i was trying your suggestion also:
public class IconRenderer extends DefaultTreeCellRenderer {
     private static final long serialVersionUID = 1L;
     Icon SelectedIcon;
     Icon NotSelectedIcon;
    public IconRenderer(Icon SelIcon,Icon NoTSelIcon) {
         SelectedIcon = SelIcon;
         NotSelectedIcon = NoTSelIcon;
    public Component getTreeCellRendererComponent(JTree tree,Object value,boolean sel,boolean expanded,
                                                    boolean leaf,int row,boolean hasFocus)
         super.getTreeCellRendererComponent(tree, value, sel,expanded, leaf, row,hasFocus);
         if (leaf )
              //setIcon(SelectedIcon);
              this.setLeafIcon(SelectedIcon);
              //this.setClosedIcon(SelectedIcon);
              //this.setOpenIcon(SelectedIcon);
         return this;
}in leaf nodes it was working fine but my problem here was with the parents.
what i mean is :
//this.setClosedIcon(SelectedIcon);
//this.setOpenIcon(SelectedIcon);
it marked the entire tree.
thanks
