I want to create a JTree, and each node of the JTree has a name, and when you click on the node, a textarea will be expanded, I did some research online but didn't find anything useful. 我想创建一个JTree，并且JTree的每个节点都有一个名称，当您单击该节点时，将扩展文本区域，我在线进行了一些研究，但没有发现任何有用的东西。 Could anyone tell me if this possible to achieve? 谁能告诉我这是否可以实现？ if yes, could you please post a simple code sample? 如果是，请您发布一个简单的代码示例？

You dont need JTextAreas, JTree has the ability built-in to make Nodes editable. 您不需要JTextAreas，JTree内置了使Nodes可编辑的功能。 Take a look at this example: 看一下这个例子：

I just tried it out to make sure it works. 我只是尝试了一下，以确保它可以工作。 Compile & Run. 编译并运行。 Click on one of the Nodes then press F2 to edit it. 单击节点之一，然后按F2键对其进行编辑。 Please comment if you have questions or if this is not what you are looking for. 如果您有疑问或不是您要的内容，请发表评论。
