Java：WindowAdapter windowClosed方法未运行 [英] Java: WindowAdapter windowClosed method not running
问题描述
我目前正在一个扩展JFrame的类中运行这个。当我关闭窗口时，我在控制台中看不到 RAN EVENT HANDLER 。这不是主窗口，而且这个窗口的多个实例可以同时存在。
I'm currently running this in a class that extends a JFrame. When I close the window, I don't see RAN EVENT HANDLER in the console. This is not the main window, and more than one instance of this window can exist at the same time.
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosed(WindowEvent e) {
System.out.println("RAN EVENT HANDLER");
}
});
此方法位于一个名为 initialiseEventHandlers（）在构造函数中调用，所以我确定代码正在运行。
This method is inside a method called initialiseEventHandlers() which is called in the constructor, so I'm sure the code is running.
我做错了什么？
谢谢！
编辑：这是完整的（总结）代码：
Here's the full (summarised) code:
public class RacesWindow extends JFrame {
private JPanel mainPanel;
private JLabel lblRaceName;
private JTable races;
private DefaultTableModel racesModel;
public RacesWindow() {
this.lblRaceName = new JLabel("<html><strong>Race: " + race.toString()
+ "</strong></html>");
initialiseComponents();
this.setMinimumSize(new Dimension(500, 300));
this.setMaximumSize(new Dimension(500, 300));
initialiseEventHandlers();
formatWindow();
pack();
setVisible(true);
}
public void initialiseComponents() {
mainPanel = new JPanel(new BorderLayout());
races = new JTable();
racesModel = new DefaultTableModel();
races.setModel(racesModel);
}
public void initialiseEventHandlers() {
System.out.println("EVENTHANDLER CODE IS CALLED"); //for debugging
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosed(WindowEvent e) {
System.out.println("RAN EVENT HANDLER");
appManager.removeOpenWindow(race.toString());
}
});
}}
public void formatWindow() {
mainPanel.add(lblRaceName, BorderLayout.NORTH);
mainPanel.add(new JScrollPane(races), BorderLayout.CENTER);
mainPanel.setBorder(new EmptyBorder(10, 10, 10, 10));
this.add(mainPanel);
}
}
推荐答案
发现我使用错误的方法： windowClosed（）。我应该使用 windowClosing（）！
I found out I was using the wrong method: windowClosed(). I should use windowClosing()!
