UI tab updates for Handler switch in e4 application model

Question

I defined the global command for my e4 application, namely the add command. So, as you can see in the command should be used throughout the application (1) and the repsective handler, which will be activated when the context switches accordingly. parts in (2) and (3).

Now, what I'm missing is the ability to update all contributions to the user interface, such as (4) assigned to the team (1), with information such as (2) add a contact, and when switching to (3) add an account.

What is the general recommended way to update all tabs of the command user interface, given the actual context of the command (which handler is active, etc.). In Eclipse 3.x, we had something like IElementUpdater that was doing the corresponding update.

Thanks for your tips! - Discussed in parallel at the Eclipse Forum

I worked on finding a solution and outlined the current status on my blog .

Answer 1

You can enter IEventBroker in your class operator and below, this operator will check all the features of the user interface in the application

eventBroker.send(UIEvents.REQUEST_ENABLEMENT_UPDATE_TOPIC, UIEvents.ALL_ELEMENT_ID);
