水平扩展JTree
看起来可能有点奇怪，但是有没有办法让 JTree 的最后一个节点水平扩展而不是垂直扩展呢？ 我的垂直树节点代表不同的讨论主题（政治、文化等），每个节点都有一个 Article 对象列表。我确实需要按发布日期对这些文章进行排序，并将它们水平放置在最后一个树节点中。
我希望我说得很清楚，非常感谢任何帮助或链接。谢谢你！
It may seem a little bit strange, but is there a way to make the last node of JTree expand horizontally rather than vertically?
My vertical tree nodes represent different discussion subjects (politics, culture, etc.) and each of those nodes has a list of Article objects. I really need to sort these articles by publication date and place them in the last tree node horizontally.
I hope I was clear, any help or a link is very appreciated. Thank you!

您必须重写
JTree的paintComponent()方法并计算绘制最后一个节点的时间。如果是的话，您将重新定位JLabel的绘画起点，我认为它代表一片叶子。问候，

You would have to override the
paintComponent()method forJTreeand calculate when you were painting the last node. If you were, you would reposition the start point of the painting for theJLabelwhich I believe represents a leaf.Regards,
