Yes, I figured but also have a lot of concerns:

Given that our waste-widget is living in a pane on a window, together 
with other widgets that can have the focus, we will have to choose from 
the following list:

		GetEventDispatcherTarget
		GetWindowEventTarget
		GetControlEventTarget
		HIObjectGetEventTarget
		GetUserFocusEventTarget

The first two won't cut it, because once the focus is on a 
non-waste-widget we experience crashes because our waste-widget is 
trying to handle key downs, while it shouldn't (and we deactivated our 
WEReference). The safest would be to use number 3 or 4, but it also 
raises the question why you are not grabbing your GetControlEventTarget 
or HIObjectGetEventTarget? Or should we use WESetEventTarget(nil) when 
we deactivate the widget? GetUserFocusEventTarget will not necessarily 
provide command keys, which waste 3 expect to arrive as well.

Is there a WASTE api that provides the ControlRef or HIObject, and can 
the waste-widget also live on a non-composited window (alluding to 
ControlRef or HIObject)?

For your info: each waste-widget we create on the window has its own 
WEReference.
