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.

Thinking of hundres of views getting any part injected just to see, if the injected part were theirselves sounds kind of odd to me.

Hey Tom,

thanks for your advice.

Currently I like the IFocusable behavior, even though I need to associate the MPart with the class implementing the view abusing the setObject(), currently (everything's composite :))

Thinking of hundres of views getting any part injected just to see, if the injected part were theirselves sounds kind of odd to me.
