篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Java Swing JWindow应用程序崩溃相关的知识,希望对你有一定的参考价值。
如果我使用JDK1.8_40或更新版本(Oracle或OpenJDK执行相同操作),以下代码和对话框调整大小将使应用程序崩溃(尝试过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;
}
}
我还没有发现其他有关此问题的投诉,并且尚未在oracle的网站上发布错误。一个可能的解决方法是将JWindow更改为未修饰的JDialog,但这对我来说还有其他问题,所以我不会改变它。
有没有其他人遇到这个问题并找到了解决方法?

答案
这个答案有点晚了,but the issue has been fixed。
另一答案
您的Timer不会在Swing UI线程上调度Swing UI事件。你需要“invokeLater”你的runnable所以它在正确的线程上运行。
或者,您可以让计时器执行SwingWorker,使用done()方法发布事件(保证在事件派发线程上)
