I'm attempting to take an existing plugin and have it honor the dark and light themes. The plugin is not an e4 plugin. I'm having trouble figuring out how to get the styling engine. In an e4 project it looks easy, you just use injection. Here is my lame attempt that didn't work

I'm using Eclipse 4.26

		IEclipseContext context = Workbench.getInstance().getContext();
		IStylingEngine iStylingEngine = null;
		if (context != null)
			iStylingEngine = context.get(IStylingEngine.class);
		System.out.println(iStylingEngine);

The styling engine comes back as null. This wouldn't be a great solution even if it worked, the Workbench.getInstance() is not public API.

How do I get the styling engine?

This seems to work.

		
		IStylingEngine iStylingEngine = null;
		Optional<MApplication> optApplication = PlatformUI.getApplication();
		if (optApplication.isPresent()) {
			MApplication application = optApplication.get();
			IEclipseContext context = application.getContext();
			if (context != null)
				iStylingEngine = context.get(IStylingEngine.class);
		}
		System.out.println(iStylingEngine);
