如何关闭多个JFrame和JDialog窗口?

问题描述

我正在开发一个具有多个JFrame和JDialog窗口的程序.

I'm working on a program which has multiple JFrame and JDialog windows.

我有一个包含一个按钮的JFrame，当我单击该按钮时，将打开一个JDialog窗口.在此JDialog窗口中，还有另一个按钮，单击该按钮将打开第二个JDialog窗口.在第二个JDialog窗口中，我有一个最后一个按钮.

I have a JFrame which contains a button, when I click on this button a JDialog window opens up. In this JDialog windows there is another button, which when is clicked it opens up a second JDialog window. In the second JDialog window I have a last button.

我想做的是，当单击最后一个按钮时，同时关闭JDialog窗口和JFrame窗口.

What I want to do is to close both JDialog windows and JFrame window when this last button is clicked.

打开订单的方式如下:

JFrame Frame1;
JButton Button1;

JDialog Dialog1;
JButton Button2;

JDialog Dialog2;
JButton Button3;

Button1ActionPerformed(ActionEvent e){
   new Dialog(Frame1Frame);
}

Button2ActionPerformed(ActionEvent e){
    new Dialog2(Dialog1Frame)
}

Button3ActionPerformed(ActionEvent e){
   //Here I wnat to add the code that closes JDialog2 JDialog1 and JFrame1 windows.
}

我尝试了super.dispose();，但是它不起作用.有什么想法吗?

I have tried super.dispose(); but it doesn't work. Any ideas?

推荐答案

如此处所示，使用 Action ，您的actionPerformed()实现可以将WINDOW_CLOSING事件调度到所需的Window实例.

As shown here using Action, your actionPerformed() implementation can dispatch the WINDOW_CLOSING event to the desired Window instances.

@Override
public void actionPerformed(ActionEvent e) {
    d1.dispatchEvent(new WindowEvent(d1, WindowEvent.WINDOW_CLOSING));
    d2.dispatchEvent(new WindowEvent(d2, WindowEvent.WINDOW_CLOSING));
    f1.dispatchEvent(new WindowEvent(f1, WindowEvent.WINDOW_CLOSING));
}
