messagingmodule.cpp

python s60 1.4.5版本的源代码

/*
* ====================================================================
*  messagingmodule.cpp  
*  
*  Python messaging services on Symbian OS
*
*  Implements currently the following Python classes / methods:
*
*   Messaging
* 
*   sms_rsend(string, unicode_string)
*   mms_send(unicode_string, unicode_string, unicode_string)
*
*  TODO
*   o Add delete of Messaging object to the wrapper and implement the
*     deletion for finer-grained control and advanced API
*   o Expose the Messaging object to the end developer
*   o Adding delete from Outbox into module inbox might be the easiest
*     way to delete an ongoing send request if an ongoing send does not
*     panic the client
*   o Unify and merge inbox and messaging?
