在普通的命令处理程序中,我可以添加新的选项卡/部分作为此代码:
@Execute
public void execute(Shell shell, EPartService partService, MApplication application,EModelService modelService) throws URISyntaxException{
MPart part = MBasicFactory.INSTANCE.createPart();
part.setLabel("New file ");
part.setCloseable(true);
part.setContributionURI("bundleclass://com.xxx.rcp.app.item_editor/com.xxx.rcp.app.item_editor.parts.ItemEditorPart");
List<MPartStack> stacks = modelService.findElements(application, "com.xxx.rcp.app.partstack.2", MPartStack.class, null);
stacks.get(0).getChildren().add(part);
partService.showPart(part, PartState.ACTIVATE);
}
现在我想在一个IEventBroker handleEvent中添加新标签/部件。
首先,我在Activator中注册主题:
@Override
public void start(BundleContext context) throws Exception {
IEclipseContext serviceContext = EclipseContextFactory.getServiceContext(context);
IEventBroker eventBroker = serviceContext.get(IEventBroker.class);
eventBroker.subscribe("MY_TOPIC", ContextInjectionFactory.make(OpenItemEditorHandler2.class, serviceContext));
}
然后,我在handleEvent中添加了tab / part:
public class OpenItemEditorHandler2 implements EventHandler {
// @Inject
// private IEclipseContext serviceContext;
// @Inject
// EPartService partService;
// @Inject
// MApplication application;
@Inject
IEclipseContext serviceContext;
// @Inject
// EModelService modelService;
// @Inject
// private ECommandService commandService;
//
// @Inject
// private EHandlerService handlerService;
@Override
public void handleEvent(Event event) {
MPart part = MBasicFactory.INSTANCE.createPart();
part.setLabel("New file ");
part.setCloseable(true);
part.setContributionURI("bundleclass://com.xxx.rcp.app.item_editor/com.xxx.rcp.app.item_editor.parts.ItemEditorPart");
// get the part stack and show created part
EModelService modelService = serviceContext.get(EModelService.class);
MApplication application = serviceContext.get(MApplication.class);
List<MPartStack> stacks = modelService.findElements(application, "com.xxx.rcp.app.partstack.2", MPartStack.class, null);
}
由于null all,我无法访问或注入这些服务。为什么?我在OpenItemEditorHandler2
中注入了对象Activator
。
或者您可以提供一些关于添加新标签/部分的其他解决方案的提示吗?
非常感谢!

EclipseContextFactory.getServiceContext
返回的上下文仅包含OSGi服务,不包含大多数正常的e4服务,因此您无法使用它来创建您的类。这意味着激活器不适合设置您的订阅。
您需要在可以访问正确的eclipse上下文的地方设置subscribe。 <{1}}或RCP AddOn
可能适用。
在LifeCycle
构造函数中,您可能有:
