我很好奇如何valueChanged在JTable双击行中时调用重写方法.现在,下面的代码片段实现了一个单击操作或事件箭头键,以便在人员列表中导航并进行相应调整JLabel.我正在尝试做的是类似于我点击一次的类似事情,但这次IF和ONLY如果双击一行dto就会改变其他事情.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() + " …

例如,执行用于显示各种列的长语句时的问题之一

 select g.guestid, g.forename, g.surname, b.bookingid,
 b.arrivedate, b.departdate, br.floorno, br.roomno from...

Linux终端上的列大小似乎是一个问题.例如,Forename VarChar(80)列在执行上述语句时占用屏幕的大部分宽度,并且一种方法可以通过以下方式将其删除:

SET COLUMN FORENAME FORMAT A10

例如.但是,许多专栏需要反复进行,这很长.即

SET COLUMN FORENAME FORMAT A10
SET COLUMN SURNAME FORMAT A10

等等...

有没有办法说根据文字宽度调整列宽,以便每个人都很好地适应.而不是这样..

我更喜欢一些不涉及使用FUNCTIONS的解决方案.

public class EventController extends MouseAdapter implements ActionListener {

    private EventModel model;
    private EventView  view;
    String tableClick;
    Events events;    

    /** Constructor */
   public EventController(EventModel myModel, EventView myView){
       model = myModel;
       view = myView;     
   }

   public void setUpListeners() {
       this.view.addEventButton.addActionListener(this); 
       this.view.addEventMenuItem.addActionListener(this);
       this.view.editEventMenuItem.addActionListener(this);
       this.view.tableEvent.addMouseListener(this);                
   }

   @Override
   public void actionPerformed(ActionEvent e){
       Object button = e.getSource();
       if(button==this.view.addEventButton) {
           setEventDetails();          
       }                
   }

   @Override
   public void mouseClicked(java.awt.event.MouseEvent event) {
      int rowSelected = view.tableEvent.getSelectedRow();
       //blahblahblah
      view.changeDisplay(events);
    }

我如何覆盖keyPressedKeyListener类的方法,就像我已经完成的那样mouseClicked,ActionPerformed我真的不想覆盖keyTyped它keyReleased,只是 …

我在main方法中创建了一个logger实例,并将其设置为全局变量.如果我想使用相同的日志文件来记录消息,那么将相同的记录器实例传递给不同的类构造函数是一种好习惯.你怎么能这样做而不是通过.

public static void main(String[] args) {
        Date date = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-HH:mm:ss");
        Handler h = new FileHandler("../logs/MyLogFile_"
                + sdf.format(date) + ".log", true);
        h.setFormatter(new SingleLineFormatter());
        h.setLevel(Level.ALL);
        logger.setUseParentHandlers(false);
        logger.addHandler(h);
} 

public void go(XMLConfig config) throws Exception {      
    Controller.setGlobalErrorHandler(new ErrorHandler(logger));
} 

public class ErrorHandler implements FDSErrorHandler {

    private static Logger logger = Logger.getLogger("com.explore.lse");

    public ErrorHandler(Logger logger) {
        this.logger = logger; 
    }
}
