How do I exit a NetBeans Platform GUI application?

Question

如何在XML文件中声明TopComponent时以编程方式正确退出NetBeans平台应用程序？

Answer 1

I'm not sure what you mean by "when the TopComponent has been declared in an XML file" but the answer for how to properly exit a NetBeans Platform application is:

LifecycleManager.getDefault().exit();

What you definitely should not do is the normal Java way: System.exit(); .
