[GnomeMeeting-devel-list] [PATCH] private text chat

Hi,

this patch makes two things:
1) put the structures internal to the text chat in a private part of the
GmTextChat struct ;
2) clean the api ; it is now used like this :
chat = gnomemeeting_text_chat_new ();
tip = gnomemeeting_text_chat_foo (chat, ...); 
... (other uses, first argument is always GmTextChat*)
gnomemeeting_text_chat_destroy (chat);

Snark
