Hi,

please pardon me about this question, but how is a e4 view is to be notified about having focus?

I've seen the IFocusable interface in org.eclipse.e4.workbench.ui.behaviors, but how is the setFocus() method getting called ?
Do I need to implement my own IPartListener?

Hi,

I think the IFocusable interface (Could you file a bug that we remove it
from the sources please) is a left over from 0.9. I think that there are
2 possibilities:

a) By registering an IPartListener on the EPartService
b) By getting the IServiceConstants.ACTIVE_PART injected into your
component and checking if the MPart passed is you.

I would have expected that one could also get this information by
subscribing to the EventBus but when looking at the implementation it
looks like this not supported there yet.
