How to add a type of listener to a JTable (Java)?
提问by Confiqure
I have a column with plain text in it.
我有一个包含纯文本的列。
If the user double-clicks a row in that column, the column allows itself to be edited for that row (as it should).
如果用户双击该列中的一行，则该列允许针对该行进行编辑（应该如此）。
I need something to detect when that text is done with being edited (when the user hits the enter key, for example). When that happens, I need something to get the row ID of that change (0-based of course).
我需要一些东西来检测该文本何时完成编辑（例如，当用户按下 Enter 键时）。发生这种情况时，我需要一些东西来获取该更改的行 ID（当然是基于 0）。
Any ideas?
有任何想法吗？

You should add a listener to the TableModel:
您应该向 TableModel 添加一个侦听器：
table.getModel().addTableModelListener(new TableModelListener() {
public void tableChanged(TableModelEvent e) {
// your code goes here;
}
});
TableModelEventcontains row and column number and type of modification.
TableModelEvent包含行列号和修改类型。

I think the easiest way to get the location of the click in terms of row and column would be this:
我认为根据行和列获取点击位置的最简单方法是：
table.addMouseListener(new java.awt.event.MouseAdapter() {
@Override
public void mouseClicked(java.awt.event.MouseEvent e) {
int row = table.rowAtPoint(e.getPoint());
int column = table.columnAtPoint(e.getPoint());
if (row >= 0 && column >= 0) {
......
}
}
});
