Eclipse RCP: how to register an ISourceProviderListener

问题

today i tried the following:

I have:

• a View with a form (FormView)
• a AbstractSourceProvider (Provider) to provide changes in FormView to the world
• a View (ConsumerView) that should consume information from Provider it implements ISourceProviderListener

FormView updates the Provider, which fires the fireSourceChanged. But how can I register the ConsumerView so that it listens for changes in the Provider?

This answer here on stackoverflow, did not really explain how to do it: How to communicate between views in Eclipse RCP?

Also Lars Vogels tutorials on RCP Commands are mentioned frequently, but I don't get it from there.

Thanks for your help in advance!

回答1:

From within your ConsumerView createPartControl(..) method:

ISourceProviderService service = (ISourceProviderService)getSite().getService(ISourceProviderService.class);

ISourceProvider yourProvider = service.getSourceProvider("yourSourceProviderName");

yourProvider.addSourceProviderListener(this);
