Java中的侦听器顺序

问题描述

我编写了自己的表格单元格编辑器，扩展了 AbstractCellEditor 并实现了 TableCellEditor ， ItemListener ，以及 MouseListener 。有没有办法在 itemStateChanged 方法之前先执行 mouseClicked 方法？我正在尝试执行以下操作：

I wrote my own table cell editor that extends an AbstractCellEditor and implements a TableCellEditor, an ItemListener, and a MouseListener. Is there a way I can have the mouseClicked method be executed first before the itemStateChanged method? I'm trying to do the following:

private int rowClicked;
private JTable table;

public void itemStateChanged(ItemEvent e) {
  if (rowClicked == 5) {
    // Do something to row 5.
  }
}

public void mouseClicked(MouseEvent e) {
  Point p = e.getPoint();
  rowClicked = table.rowAtPoint(p);
}
