如何将下拉菜单添加到JTable单元格 [英] How to add a drop down menu to a JTable cell

问题描述

这可能是之前提出的问题。我在帖子之前搜索了很多，但是找不到任何可接受的。

This may be a question asked before. I searched a lot before posting here, but couldn't figure out any acceptable one.

有人可以告诉我如何做到这一点。我只需要在单击单元格时获得一个下拉菜单，这样我就必须从中选择一个值（作为限制用户选择的方式）。

Can some one show me a way how to do this. I simply need to get a drop down menu when i click on the cell so that I'll have to select a value from that (as a way to restrict the user selection).

如果有人可以提供帮助，我相信它会帮助很多人。有很多类似的问题，但没有任何明确的答案。请回答一下细节。一个例子将非常感谢..

If some one can help with this I believe it will help a lot of people out there. There are a lots of questions similar to this but no any clear answer. Please answer with a bit more details. An example would be much appreciated..

谢谢！

推荐答案

• 使用带有DefaultTableModel的 DefaultCellEditor对于JTable ，如果所有 JComboBoxes 在具体的TableColumn中具有相同的值

  • use DefaultCellEditor with DefaultTableModel for JTable in the event that all the JComboBoxes will have identical values in the concrete TableColumn

    如果没有相同的值，则使用 DefaultCellEditor 为 JComboBoxes 使用自定义 AbstractTableModel

    if will have not identical values, then to use DefaultCellEditor for JComboBoxes with custom AbstractTableModel
