推荐答案

你需要到CustomCellRenderer实现TreeCellRenderer，并将它附加到JTree。

You will need to CustomCellRenderer which implement TreeCellRenderer, and attach it to JTree.

在CustomCellRenderer中，你可以放置按钮和图标。

In your CustomCellRenderer you can put button and icon.

JTree tree = new JTree(rootVector);
TreeCellRenderer renderer = new CustomCellRenderer();
tree.setCellRenderer(renderer);

检查此示例:(从上面引用上面的代码）
