Hi,
I have to extend xiff with two new namespaces:
First ext. will xiff enable to show composing events from other clients, second will allow xiff to show the real date a message was composed when receiving history messages from a chatroom. Now it shows the time it arrives at the client, which is wrong.
What’'s the easiest way to get support for the extenstinons above. Is there a hook in the xiff code where I have to add this?
Thanks for any hints!
Guido
Hi guido,
I’‘ve have been trying to add the composing event to some of my code by writing a new MessageEventExtension according to JEP-0022. It works but it’‘s not finished yet and I’‘m still trying to work out if I’'m taking the wright approach.
here’'s an OLD UNFINISHED /b version of my class code…

/code
you can then send the composing event somewhat like this
this piece of code is part of another applicationclass[/i]
// all your other (class) code for making the connection etc… goes here
// don’'t forget to import the extension…
// import org.jivesoftware.xiff.data.messageEvent.messageEventExtension;
public function sendComposing( jid:String):Void{
var tempMessage:Message = new Message( jid, null, “”, “”, Message.CHAT_TYPE );
var mEvent:messageEventExtension = new messageEventExtension(tempMessage.getNode());
mEvent.addEvent(“composing”);
tempMessage.addExtension(mEvent);
// conn is an instance of the connection class
conn.send( tempMessage );
}
/code
Hope this helps

Thanks for your reply. At least somone with the same problems out there . I think together we will come along the problems. I will try this out and let you know my experiences!
