在JTree中只处理树将展开而不是树选择- Java Swing

import javax.swing.*;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
import javax.swing.tree.TreePath;

public class CustomJTree extends JTree {
    public CustomJTree(DefaultMutableTreeNode root) {
        super(root);
    }

    @Override
    public boolean isPathSelected(TreePath path, boolean includeAncestors) {
        return false; // 忽略树节点的选择操作
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Custom JTree Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
        DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Node 1");
        DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Node 2");
        root.add(node1);
        root.add(node2);

        CustomJTree tree = new CustomJTree(root);
        JScrollPane scrollPane = new JScrollPane(tree);
        frame.add(scrollPane);

        frame.setSize(300, 200);
        frame.setVisible(true);
    }
