What I'm trying to do is create a JTree with each cell containing normal text but also containing a right-aligned text for each cell (right-aligned to the edge of the tree, regardless of the hierarchy level).
我要做的是创建一个JTree，其中每个单元格包含普通文本，但也包含每个单元格的右对齐文本(无论层次结构级别如何，右对齐到树的边缘)。
I've tried creating my own TreeCellRenderer, but the cells' sizes are not being updated. I also tried this idea with a custom tree UI but am experiencing similar issues.
我尝试过创建自己的TreeCellRenderer，但是单元格的大小没有被更新。我也用自定义树UI尝试了这个想法，但也遇到了类似的问题。
I also have tried creating a custom component with a JPanel "glued" to the right of the tree. This has been the most successful, but I have been unable to have the tree cells extend to the right and touch this extra panel:
我还尝试过创建一个自定义组件，将JPanel“粘合”在树的右边。这是最成功的，但我一直无法让树细胞向右延伸并触摸这个额外的面板:

You could try to use a JXTreeTable, from the SwingX package.
您可以尝试从SwingX包中使用JXTreeTable。

You would define then such an object with two columns (one for the tree, to other for the right aligned text), and it should work out fine.
然后您将定义这样一个具有两个列的对象(一个用于树，另一个用于正确对齐的文本)，并且它应该可以很好地工作。
To prevent it from looking like a table, though, I would recommend you to deactivate the header (setTableHeader(null)), and use their "packing" methods, to have the columns on optimal size.
但是，为了防止它看起来像一个表，我建议您禁用header (setTableHeader(null))，并使用它们的“打包”方法，使列达到最佳大小。
