Question

我有这个项目，它允许用户在其中创建自己的项目并将其保存并做更多事情。我使用Eclipse程序在Java中完成所有这些操作。今天我主要想知道如何展示层次结构？我会更具体一点，当用户创建一个项目时，它会问他们想要在哪里有项目文件夹。让我们说他们选择一个文件夹名称JavaProjects和它在那里桌面（我使用Windows，如果它在Mac和Linux上不一样），并在该文件夹中他们有一个Scripts文件夹和一个艺术文件夹，并在他们有艺术文件夹一个纹理文件夹和一个徽标文件夹（我也在脑海里想出这些文件夹）我怎样才能在JPanelEast中显示一种格式，就像Eclipse中的Package Explorer一样？我能够只扫描他们放入的文件夹，并将所有文件夹和文件整齐地排列出来吗？或者我是否需要根据我的知识做更多的事情？

如果它有帮助，这是我的代码，减去菜单栏和动作监听器

Java Tutorial中有一节介绍如何使用TreeViews。 http://docs.oracle.com/javase/tutorial/uiswing/components/tree.html

我在这里发布链接，因为这对于一个简单的答案来说有点复杂。
