Typically in large applications you have:

- One view (possibly with a controller associated) for toolbars and
menubars (BarsView and possible BarsCtrl)

- M views to decompose the rest of the application presentation

- N controllers (N <= M) to decompose the controllers of the M views

Now you want some (not necessarily all) controls in the menu and toolbars
to be handled in the N controllers, to keep locality.

The way I always solve this problem is:

1. Each of the M views contains its own actions to be later associated to
the UI manager allocated in BarsView

2. The signal handlers of the actions are located in the N controllers,
attached automatically when views and controllers are connected each other.

3. BarsView creates and handles the UIManager. This Bars view has the
visibility of all M views (throught the ApplicationView which stays at
top-level and has to be passed down to BarsView's constructor. In this way
the BarsView can access the actions allocated in the M views to associate
them in the UIManager.

Let me think what you think about this, and if it is not clear enough I
will try to make an example.
