The new Notifier→Observer relation chain:
* Conversation → ConversationItem, ConversationView
* User → UserListItem, UserInfoWindow, UserPopUp
* Contact → RosterItem
These line up pretty intuitively― if something changes in the conversation, you
want the list item and view to change too.
But there's one more here that's less intuitive:
* User → Conversation
If Conversation observes something from a user (i.e., status change), it
immediately knows to do one thing only: invalidate the user list, because
something's changed.
Two new messages were added to the protocol API to do this:
M_ROOM_PARTICIPANTS, which can be used when someone joins a room, or
on joining a room to send a full list of users, and IM_ROOM_PARTICIPANT_LEFT,
for when a user has left the room/disconnected.
IM_SET_STATUS no longer assumes received data comes from contacts, but
any general user.
UserItem was made to reflect changes in the User's name.
Chat messages can now be reliably received in a given room. :)
UserListView and UserItem were added as the backbone of the user-list,
and the (currently unused) Caya message CAYA_SEND_INVITE was established
for inviting users to rooms.
Some menus were reworked (e.g., pop-ups of the RosterListView) or
generally tweaked to be more sensical or consistent.
This is a commit with it's foot in a lot of places, but:
The Conversation class was created as the abstraction of chats: All
ImMessages that are relevant to a conversation get routed through it,
meta-data on chats is stored in it (even if right now that's basically
limited to the user list and ID).
Server was given more methods to help accessing contacts―
ContactById(BString) and AddContact(Contact*). This better allows
Conversations to add and fetch Contacts as necessary. Right now, all
users in chats are treated as Contacts, so in the future creating an
independent userlist for Server (fUserMap?) would be useful.
Server also now stores all Conversations (fChatMap) and has some
convenience methods like for Contacts: Conversations(),
ConversationById(BString), and AddConversation(Conversation*).
CayaRenderView has been changed to not store user nicks, and will use
the appropriate nick of any arbitrarily-numbered user.
Users also have a map of all Conversations they are a part of
(fChatMap).
The Remove* methods of KeyMap now return the removed item.
This dichotomy is useful and necessary in multi-user chats, so I split
Contact into a parent class, User. User should be used for generic
members of rooms, Contact used mainly with the roster.
