JTree dom4j 重写 getTreeCellRendererComponent时的问题

[大写的池]

将XML显示到JTree上以编辑

相关代码如下 此处Node
为
import org.dom4j.Element;
import org.dom4j.Node;
错误异常：
javax.swing.tree.DefaultMutableTreeNode cannot be cast to org.dom4j.Node
请达人提供解决方法

public class treeCellRender extends JLabel implements TreeCellRenderer {

	@Override
	public Component getTreeCellRendererComponent(JTree tree, Object value,
			boolean selected, boolean expanded, boolean leaf, int row,
			boolean hasFocus) {
		// TODO Auto-generated method stub
		Node node=(Node) value;
		this.setText(((Element)node).getText().toString());
		if(selected){
			
			this.setForeground(new Color(0,0,255));
		}else{
			this.setForeground(new Color(0,0,0));
		}
		return this;
	}

}

类型转换错误

当然是类型转换错误，

有什么解决的方法没？

[shijianhao]

public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean selected, boolean expanded, boolean leaf, int row,
boolean hasFocus) 这里的Value是DefaultMutableTreeNode类型，如果将它转为 Node（你的类）当然不行了啊。Node node =（Node）((DefaultMutableTreeNode)value).getUserObject();这样。getUserObject（）获取节点中我们自己的对象。
