关闭所有Java子窗口 [英] Close all Java child windows

问题描述

在Java Swing中，是否可以找到并关闭当前正在显示的所有JDialog对象?

In Java Swing is there a way to find and close all JDialog objects currently being displayed?

我有一个大型应用程序，可以调用多个部分来显示一个对话框，但是我希望能够从单个角度检测并关闭该对话框.

I have a large application and there are multiple parts that can call to display a dialog but from one single point I want to be able to detect and close it.

推荐答案

保留对每个对话框(可能是集合中)的引用.需要时，迭代集合并调用dialog.setVisible(false).

Keep a reference to each of the dialogs (perhaps in a collection). When needed, iterate the collection and call dialog.setVisible(false).

按照@mKorbel的建议，您还可以使用:

As suggested by @mKorbel, you can also use:

Window[] windows = Window.getWindows();

在迭代数组并关闭内容时，您只需要检查父"窗口即可.

You'd just need to check for the 'parent' window when iterating the array and closing things.
