如何中断 Eclipse RCP 关闭
我有一个 Eclipse RCP 应用程序插件。每当特定视角关闭或应用程序关闭时，我需要检测场景，并且根据结果，我可能需要取消应用程序或视角的关闭。如果我可以访问应用程序的 WorkbenchAdvisor 类，那么这将是微不足道的。作为此应用程序的插件，我如何检测事件以及如何告诉主应用程序/顾问我需要取消关闭？
I have a plugin into an eclipse rcp application. I need to detect a scenario whenever a particular perspective is closed or if the application is closed and based on the outcome, I may need to cancel the closing of the app or perspective. If I had access to the application's WorkbenchAdvisor class, this would be trivial. As a plugin to this app, how can I detect the event and how can I tell the main application/advisor that I need to have the close canceled?

您是否考虑过安装 IWorkbenchListener 并扩展
preShutdown方法？看来您可以使用此机制否决关闭。Have you looked at installing an IWorkbenchListener and extending the
preShutdownmethod? It appears you can veto a shutdown using this mechanism.我想你想做的事是不可能的。如果插件可以阻止 rcp 应用程序关闭（或以其他方式强制其关闭），这可能是一个严重的安全问题。此外，应用程序状态也不清楚，因为它可能已经释放了一些资源。
如果应用程序想要将程序终止的控制权交给插件，它应该定义一个可以使用的接口/扩展点。
I think want you want to do is not possible. If a plug-in could prevent an rcp application to shut down (or the other way force it to should down) this can be a serious security problem. Also the app state would be unclear as it might has released some resources.
If an app wants to give control of program termination to a plug-in it should define an interface/extension point that can be used.
