Java Swing JWindow應用程序崩潰

Question

如果我使用JDK1.8_40或更新版本（Oracle或OpenJDK執行相同操作），以下代碼和對話框調整大小將使應用程序崩潰（嘗試過Windows 7，x64,64位JDK）

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
import javax.swing.JWindow;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Main {

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            final JDialog dialog = new JDialog();
            dialog.add(new JPanel());
            dialog.setVisible(true);
            dialog.setBounds(100, 100, 100, 100);

            final JWindow dependentWindow = getjWindow(dialog);
            dependentWindow.setVisible(true);
            dependentWindow.setBounds(100, 100, 100, 100);
            Timer t = new Timer(300, new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    dependentWindow.setVisible(!dependentWindow.isVisible());
                }
            });
            t.start();
        }
    });
}

private static JWindow getjWindow(JDialog dialog) {
    JWindow w = new JWindow(dialog);
    JPanel panel = new JPanel();
    panel.add(new JButton("button"));
    w.add(panel);
    return w;
}
}

我還沒有發現其他有關此問題的投訴，並且尚未在oracle的網站上發布錯誤。 一個可能的解決方法是將JWindow更改為未修飾的JDialog，但這對我來說還有其他問題，所以我不會改變它。

有沒有其他人遇到這個問題並找到了解決方法？

Answer 1

這個答案有點晚了， 但問題已得到解決 。

Answer 2

您的Timer不會在Swing UI線程上調度Swing UI事件。 你需要“invokeLater”你的runnable所以它在正確的線程上運行。

或者，您可以讓計時器執行SwingWorker，使用done（）方法發布事件（保證在事件派發線程上）
