how to create and send a keyEvent from a xpcom object with thread?

[C�dric]

Hello all,
I know this question has already asked but I can't do it.
If someone can help me with code sample or link.


or if someone want to read my code at the end and tell me what is wrong.

thanks in advance

the following code works only in debug mode with this message : 
###!!! ASSERTION: nsDOMEvent not thread-safe: '_mOwningThread.GetThread() 
== PR_GetCurrentThread()', file nsDOMEvent.cpp, line 290

and of course I would like it works with a normal compilation

my source :
myThread(void* arg){
        ...
        nsIDOMEvent* ev=nsnull;
        nsIDOMEvent** aEv = &ev;
        if (proxyDomDocEvent) {
                proxyDomDocEvent->CreateEvent(NS_LITERAL_STRING("KeyEvents"), aEv);
        }

        nsCOMPtr<nsIDOMKeyEvent> kev=do_QueryInterface(ev);
        if (kev) {
                kev->InitKeyEvent(NS_LITERAL_STRING("keypress"),PR_TRUE,PR_TRUE,
                nsnull,PR_FALSE, PR_FALSE,PR_FALSE,PR_FALSE,myCode,myType);
                PRBool noDefault;
                //send the Event
                proxyDomDocTarget->DispatchEvent(ev, &noDefault);
        }
        ...
}       
        
Init(nsIDOMDocument *document, nsIDOMNode *nodl){

    ... 
        domDocEvent = do_QueryInterface(document);
        domDocTarget=do_QueryInterface(nod);
      //proxy Manager Creation
        nsServiceManager::GetService( NS_XPCOMPROXY_CONTRACTID,
                                      NS_GET_IID(nsIProxyObjectManager),
                                        (nsISupports **)&manager);
      //proxyCreation
        manager->GetProxyForObject( NS_UI_THREAD_EVENTQ,
                                    NS_GET_IID(nsIDOMEventTarget),
                                    domDocTarget,         
                                    PROXY_SYNC | PROXY_ALWAYS, 
                                    (void**)&proxyDomDocTarget);
        manager->GetProxyForObject( NS_UI_THREAD_EVENTQ,
                                    NS_GET_IID(nsIDOMDocumentEvent),
                                    domDocEvent,         
                                    PROXY_SYNC | PROXY_ALWAYS, 
                                    (void**)&proxyDomDocEvent);
        // thread Creation:
        myKeyThread=PR_CreateThread(PR_USER_THREAD,myThread, 
(void*)nsnull,PR_PRIORITY_NORMAL,PR_LOCAL_THREAD,PR_JOINABLE_THREAD,0);
        return NS_OK;
