valueChanged我很好奇只有​​在JTable双击一行时如何调用覆盖的方法。现在，下面的代码片段实现了单击操作或事件箭头键来浏览人员列表并进行JLabel相应调整。我正在尝试做的是类似于我单击一次所做的事情，但是这次如果并且仅当双击一行dto时会改变，否则什么也不会发生。我该怎么做呢 ：（

   class ListDataUI {

    public void addListSelectionListener(ListSelectionListener listSelectionListener) {
            summaryTable.getSelectionModel().addListSelectionListener(listSelectionListener);

 public T getSelectedDTO() {
        final int selectedRowIndex = summaryTable.getSelectedRow();
        if (selectedRowIndex != -1) {
            return data.get(summaryTable.convertRowIndexToModel(selectedRowIndex));
        } else {
            return null;
        }
    }
        }
    }




    class MainMenu extends javax.swing.JFrame {
    private void initListeners() {
    searchTable.addListSelectionListener(new ListSelectionListener() {

        @Override
        public void valueChanged(ListSelectionEvent e) {
            if (!e.getValueIsAdjusting()) {
                AcademicDTO dto = (AcademicDTO) searchTable.getSelectedDTO();
                acImgLabel.setIcon(new ImageIcon());
                label_name.setText(dto.getTitle() + " " + dto.getForename() + " " + dto.getSurname());
                label_role.setText("Role: " + dto.getRole());
                label_phone.setText("Phone: " + dto.getPhone());
                label_room.setText("Room: " + dto.getRoom());
                label_hours.setText("Hours: " + dto.getHours());
                label_mobile.setText("Mobile: " + dto.getMobile());
                if (dto.getImage() != null) {
                    acImgLabel.setIcon(new ImageIcon(dto.getImage()));
                }
            }
        }
    });
}

}


 private void initListeners() {
    contactTable.addMouseListener(new MouseAdapter() {

        @Override
        public void mouseClicked(MouseEvent e) {
            ContactDTO dto = (ContactDTO) contactTable.getSelectedDTO();
            if (e.getClickCount() == 2) {
                System.out.println(dto.getForename());
            } else {
            }

        }
    });
}

不确定上面的其余部分......

尝试这个：

mytable.addMouseListener(new MouseAdapter() {
    public void mousePressed(MouseEvent mouseEvent) {
        JTable table =(JTable) mouseEvent.getSource();
        Point point = mouseEvent.getPoint();
        int row = table.rowAtPoint(point);
        if (mouseEvent.getClickCount() == 2 && table.getSelectedRow() != -1) {
            // your valueChanged overridden method 
        }
    }
});

将事件处理程序的代码重新定位到宿主类中的私有方法中，然后在其中实现MouseListener或扩展MouseAdapter然后调用私有方法。第一步（即创建私有方法可帮助您从多个事件处理程序调用相同的逻辑）。

调用MouseHandler_MouseEvent.getClickCount()

@MooHa 您的类 ListDataUI 应该实现 MouseListener。
