突出顯示樹searchNode搜索節點的Java Swing

Question

m_searchButton.addActionListener(new ActionListener() { 
    public void actionPerformed(ActionEvent e) { 
     DefaultMutableTreeNode node = searchNode(m_searchText.getText()); 
     if (node != null) { 
      TreeNode[] nodes = m_model.getPathToRoot(node); 
      TreePath path = new TreePath(nodes); 
      m_tree.scrollPathToVisible(path); 
      m_tree.setSelectionPath(path); 
     } else { 
      System.out.println("Node with string " + m_searchText.getText() + " not found"); 
     } 
    } 
}); 

代碼（）是

public DefaultMutableTreeNode searchNode(String nodeStr) { 
    DefaultMutableTreeNode node = null; 
    Enumeration e = m_rootNode.breadthFirstEnumeration(); 
    while (e.hasMoreElements()) { 
     node = (DefaultMutableTreeNode) e.nextElement(); 
     if (nodeStr.equals(node.getUserObject().toString())) { 
     return node; 
     } 
    } 
    return null; 
} 

我寫了這個代碼頂級搜索在樹中的節點？但是我無法突出顯示找到的藍色節點。你能提供一個解決方案嗎？

您的TreeCellRenderer的實施可以指定所需的顏色。見Customizing a Tree's Display和引用的例子here。
