用Windows事件关闭JFrames

问题描述：

我正在写一个简单的程序，我有多个JFrame窗口，但是当我使用多个堆栈时，我试图将它们的可见性设置为false，这是行不通的，所以我试图模拟一个关闭，所以框架不堆叠在一起，但我不知道该怎么用，因为我的程序不是一个窗口。用Windows事件关闭JFrames

public void close(){ 
    WindowEvent winClosingEvent = new WindowEvent(this, WindowEvent.WINDOW_CLOSING); 
    Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(winClosingEvent); 
}

在这我不断收到的

incompatible types: Program1 cannot be converted to Window

一个错误。如果有人这样做，请让我知道我不能找到的工作对我来说是更好的办法更好的办法。

我的第一个问题就是**为什么**你的程序会显示多个JFrames，因为大多数真实世界的程序只显示一个主窗口？请参阅[使用多个JFrames，好/坏实践？]（http://stackoverflow.com/questions/9554636）了解更多信息。我的下一个问题是，为什么你会尝试在非窗口上调用窗口事件？ –

那么我的教授要求多个JFrames，我知道这是不切实际的，但他希望我们使用它足以理解它。我想弄清楚如何关闭它，如果一个Windows事件可以做到这一点，我厌倦了浪费时间试图解决这个问题，当我有更多的工作要做。 –

*“我试图将他们的可见性设置为false，这是行不通的”* - 是一个需要调查的问题，因为它应该工作得很好，可能的原因是，您尝试更新的框架不是一个在屏幕上 - 但这是一个猜测，我们没有一个可运行的示例演示您的问题 – MadProgrammer

答

你没有把足够的信息和说明您的具体问题，但这里是我可以帮你：要使当你点击操作系统提供的关闭按钮（通常在右上角）时，JFrame关闭，这对你来说很有用（把它放在控制你的JFrame的类中，它也扩展了JFrame类） S）：

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

要在一个特定的事件用接近一个JFrame：

this.dispose();

为了使一个JFrame看不见的使用：

this.setVisible(false);

用Windows事件关闭JFrames
