Now, per each account, there is a read-only chat view associated with
it, accessible through its item in the conversations list. This can be
used to place system messages, MOTDs, insignificant errors, etc.
Protocols can send text to this buffer by specifying no "chat_id" in
an IM_MESSAGE_RECEIVED message.
If the user has permission to change a room's subject or name, they can
now edit the text views displaying them (toward the top of the window).
When enter is pressed, the changes will be sent to the protocol.
To do this, a BTextView subclass was added to libinterface
(splitting somewhat from SendTextView)― EnterTextView sends a message
containing the text to the given target when the user hits enter sans
modifiers.
When a new message is posted (or the user is messaged), the room's item
in the roomlist is now highlighted, like Vision.
Chat also auto-scrolls when new messages are posted.
The BTextBox used for sending messages has been moved from the main
window to individual ConversationViews, allowing seperate histories,
texts, etc., to exist in different conversations.
EditingFilter (a filter that hooked into MainWindow) was previously used
to field special key combos with this textbox, including "ENTER" for
sending, but this has been replaced with a new textview subclass
(SendTextView).
New API messages were added to distinguish between a user leaving of
their own volition and being kicked/banned.
Messages are now shown in the chat view when a user leaves or or
kicked/banned, etc.
The conversation view now displays the protocol icon and room subject.
Messages for receiving room names (IM_ROOM_NAME) and subjects
(IM_ROOM_SUBJECT) were added, and support for the latter was given to
the XMPP add-on.
New message APIs were added, and several (room-related) im_what values were
moved into the 150s/160s.
UserItem::_TintColor() was moved to CayaUtils, because it can be used in
several different contexts.
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.
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.
Now all instances of sending messages (bar status changes) to a
conversation's CayaRenderView only happen when attached to the window.
Messages sent by user appear after the protocol confirms it's been sent
(IM_MESSAGE_SENT), rather than appearing right after the user sends it
to the protocol (IM_SEND_MESSAGE).
Logs are now re-enabled (since they can safely be appended under any
circumstance).
All chats now stay in a single window, which removes and switches its
current ConversationView with the appropriate one using
Conversation::GetView().
This is a stepping-stone to merging the ChatWindow into the MainWindow.
