Event bus: detecting an application level event with controllers control object?

[kylebarrow]

I'm using the recommended event bus to communicate between controllers:

Controller A

doSomething: function() {
this.getApplication().fireEvent('somthingdone','awesome');
};

Controller B

launch:function(){this.getApplication().on({
    somthingdone: this.doSomethingElse
})
},

This works but I'm wondering if it's possible to setup application level events using the controllers control object instead?

The control config can only listen for components not classes like the application. You can fire events on Ext.Viewport which is always going to be there and is global.
