Question

当我打开首选项并更新配置时，我需要关闭“旧”部分。但我遇到了一个问题。 Eclipse抛出一个异常，告诉我它没有激活Window！

我该怎么办？

您似乎正在使用应用程序EPartService尝试关闭部件。当对话框打开时，这将不起作用，因为没有应用程序部件服务所需的活动窗口。

相反，您需要使用顶级窗口的零件服务。使用以下内容获取此信息：

@Inject
EModelService modelService;
@Inject
MApplication application;

MWindow window = (MWindow)modelService.find("id of your top level window", application);

EPartService partService = window.getContext().get(EPartService.class);

如何关闭Eclipse e4 Part，当Preferences窗口打开时
