JTable单元监听器? [英] JTable cell listener?

问题描述

我正在使用JTable.每当一个单元格时，我都需要收到通知 选择更改.我试图使用ListSelectionListener，但是 当行选择更改时，我只会收到通知.如果我选择一个 新列在同一行上，我不会收到通知.我要知道什么时候 单元格被选中，而不是在更改单元格时被选中.我可以使用一个侦听器吗?

I am using a JTable. I need to get a notification whenever a cell selection change. I tried to use the ListSelectionListener but I only get notification when the row selection change. If I select a new column on the same row, I don't get notify. I need to know when the cell is selected, not when the cell is changed. Is there a listener that I can use to do this ?

推荐答案

最简单的方法是调用setCellSelectionEnabled(true)，并将对表的引用传递给侦听器.调用侦听器后，请在原始表上调用getSelectedRow()和getSelectedColumn().

The easiest way to do this is to call setCellSelectionEnabled(true), and pass a reference to your table to the listener. When the listener is invoked, call getSelectedRow() and getSelectedColumn() on the original table.

另一种方法是在表上设置行选择侦听器，在ColumnModel上设置列选择侦听器，然后找出它们的交集.

The alternative is to set a row selection listener on the table, a column selection listener on the ColumnModel, and then figure out their intersection.
