<rereads his post... smacks his forehead>
Ok, I see the confusion. Clarification:

==============================
pro _exit, top
widget_control, top, /DESTROY
end

pro action_event, event
widget_control, event.id, GET_UVALUE=action

case action of
...
'exit': _exit, event.top
...
endcase
end

pro build_gui
...

; Create 'File' menu.
wmenu = widget_button(mbar, VALUE='File', /MENU, $
EVENT_PRO='action_event')
...
w = widget_button(wmenu, VALUE='Exit', UVALUE='exit', /SEPARATOR)
...

; Create toolbar.
wtb = widget_base(tlb, UNAME='toolbar', /ROW, /TOOLBAR, $
EVENT_PRO='action_event')
...
w = widget_button(wtb, VALUE='Exit', UVALUE='exit', $
TOOLTIP='Exit program.')
...
end
==============================

I probably should have just said that in the first place, huh?
