JLabel或JTable单元格上的ActionListener [英] ActionListener on JLabel or JTable cell

问题描述

我有一个带有 JLabel [] [] 的JTable作为数据。现在我想检测双击JLabel或表格单元格（但仅在其中一列中）。如何在JLabel表格单元格上添加Action / MouseListener？

I have a JTable with JLabel[][] as data. Now I want to detect a double click on either the JLabel or a table cell (but only in one of the columns). How can I add an Action/MouseListener on JLabel respectively table cell?

推荐答案

如何：

table.addMouseListener(new MouseAdapter() {
  public void mouseClicked(MouseEvent e) {
    if (e.getClickCount() == 2) {
      JTable target = (JTable)e.getSource();
      int row = target.getSelectedRow();
      int column = target.getSelectedColumn();
      // do some action if appropriate column
    }
  }
});
