ok, that works, but... I need the TextEvent to attache some string on
the event. I would add the DOMString with the TextEvent - init-
function  (http://www.w3.org/TR/DOM-Level-3-Events/events.html#Events-
TextEvent). If I get a nsIDOMEvent it isn't possible to use this
initTextEvent(...) function.
(error: ‘class nsDerivedSafe<nsIDOMEvent>’ has no member named
‘InitTextEvent’)
So it's useless for me.
How can i call the initTextEvent method when i don't get a
nsIDOMTextEvent?
