[Adium-devl] Some questions about write a new service plugin

[Evan JIANG]

Zachary,
   Thank you very much.
   Yes, I didn't implement the host method. After add it,  issue 1&3
are fixed. But after that, when I try to set the account to offline,
it will be offline, and re-connect immediately.

About issue 2, after add host method, the [self statusType] is still
offlinetype in connect method (I print out [self statusType] after
called [super connect]).
   And issue 4, Chat_NudgeBuzzOccured is not defined in both
Adium.framework, AIUtilities.framework and FriBidi.framework. Anyway,
I found out the string value and use it as
[[adium notificationCenter] postNotificationName:@"Chat_NudgeBuzzOccured"
											  object:chat];
It works partly. I mean, the chat window will add a message like  "XXX
need your attention". But the window still doesn't shake. After look
into the AINudgeBuzzHandlerPlugin's source code, I guess it may check
the service to decide whether to shake the window.


Thank you agian. Your mail really helps me.

Best regards,
