You have to add the ALL_EVENTS keyword to your example:

pro test_event, event
help, event, /Structure
end
pro test
w=widget_base( /COLUMN, /KBRD_FOCUS_EVENTS)
item1 = widget_text(w, value='1', /EDITABLE, /ALL_EVENTS)
item2 = widget_text(w, value='2', /EDITABLE, /ALL_EVENTS)
widget_control, /REALIZE, w
xmanager, 'test', w,/JUST_REG
end

Cheers,

David
