如何在 RCP 应用程序启动后设置 window 标题

Question

I am programming an e4 RCP application and would like to set it's window title once it has started. However I could not find any way to realise that.

Reason is, I would like to add some explicit info about the running program so the user can differ between multiple launches.

Any hints on that?

In e4 you can set the main window title by calling the setLabel method of the MWindow for the main window. Use the EModelService to find the main window.

A suitable place to do this might be in an 'application startup complete' event in your RCP LifeCycle class

@Optional
@Inject
public void appStartupComplete(@UIEventTopic(UIEvents.UILifeCycle.APP_STARTUP_COMPLETE) Event event, 
                               EModelService modelService, MApplication application)
{
  MWindow window = (MWindow)modelService.find("top window id", application);

  window.setLabel("new window title");
}

Note: Event is org.osgi.service.event.Event
