JTable可点击列标题

Question

我正在尝试创建一个可单击的列标题(这样只要单击一个方法就会调用一个方法).
链接到图像(因为我还没有10个声誉)http://img156.imageshack.us/img156/5764/clickablecolumn.png
列标题是红色矩形.
到目前为止我所做的就是响应任何列字段(例如James,Benny-G和Rokas的字段)被按下.代码:

public void mouseClicked(MouseEvent e)
    {
        System.out.println("Mouse clicked");
        TableColumnModel cModel = table.getColumnModel();//cModel - column model
        int selColumn = cModel.getColumnIndexAtX(e.getX());//gets the selected column by clicked x coordinate
    }

Answer 1

您想要向表头添加一个鼠标侦听器,表示为JTableHeader:

JFrame frame = new JFrame();
frame.getContentPane().add(new JScrollPane(new JTable(4, 3) {
  {
    getTableHeader().addMouseListener(new MouseAdapter() {
      @Override
      public void mouseClicked(MouseEvent mouseEvent) {
        int index = convertColumnIndexToModel(columnAtPoint(mouseEvent.getPoint()));
        if (index >= 0) {
          System.out.println("Clicked on column " + index);
        }
      };
    });
  }
}));

frame.pack();
frame.setVisible(true);
