If a room doesn't have a set icon (and it isn't a one-on-one chat, for
which the icon'll come from the other user's avatar), the default icon
is now determined based on user count.
If there's X users, an icon with X people will be displayed, up to four.
After that, a "+" is overlayed on the icon.
Not really necessary… but I think it's cute. :-)
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.
Windows using RosterView (like for the invitiation/new chat dialogues)
have a search-box for filtering between contacts. This allows the user
to type a user ID into this search-box that isn't a contact's ID, which
can then be selected as the user.
This makes common operations (inviting a user/adding a new contact)
a little easier.
For one-on-one chats without a custom icon, the other user's avatar will
be used as the chat's icon.
A default chat icon was also added
(haiku/data/artwork/icons/WebsiteComments).
Replaces libinterface's ToolButton, a custom button that can display
a pop-up menu on click (along with a custom image). It didn't scale well
with different themes and font-sizes compared to BButtons― which
ToolButton is supposed to look like to begin with.
A BButton-derived class is used instead, so these buttons look more
in-place among other buttons.
CreateAccountMenu() is used to populate a BMenu with items corresponding
to the map of accounts provided to it― but when an account is disabled
or enabled, it can't update automatically.
A dedicated class, fAccountsMenu, now replaces it― it'll automatically
repopulate the list whenever the active accounts update.
Since libpurple doesn't mark individual account settings as "required"
or not (Pidgin will accept account settings even with all-blank answers,
unlike Cardie), every setting was marked as required by Cardie, just to
err on the side of caution.
But that's not necessary now, and was bad to begin with (especially for
Jabber, etc, with superfluous options)― in the case of libpurple, we can
follow Pidgin's example. Cardie will accept account settings with
mostly-blank options, but the add-on will send an error (and disable the
account) when it doesn't work.
Currently, add-ons are disconnected when ChatProtocol::Shutdown() is
called, which the add-on can do by itself― but there is no standard way
for add-ons to notify the app about their Shutdown. Because of this,
they tend to not call Shutdown()― instead (as in the case of the Jabber
add-on), they display a BAlert (IM_ERROR) notifying the user of the
connection error, but the account is considered active by Cardie (and
its threads are still existant, including its ProtocolLooper).
Zombies are bad, so this is redesigned somewhat with this commit:
Protocols should no longer call ChatProtocol::Shutdown() themselves,
they must send an IM_MESSAGE of IM_PROTOCOL_DISABLE to the app.
This will delete its ProtocolLooper, which in turn will send a
notification to the user and delete the ChatProtocol, and so
calling ChatProtocol::Shutdown().
In the included protocols, an IM_ERROR is sent right before
IM_PROTOCOL_DISABLE is sent if due to a connection error. This is not
required, but it is courteous to inform your user about the "why." :)
Like the notification sent when accounts are ready (IM_PROTOCOL_READY),
one's been added for when accounds have disconnected/are disabled:
IM_PROTOCOL_DISABLED.
Also, error BAlerts (created with IM_ERROR messages) are now more
detailed, showing the associated accounts' name in the header.
Connection errors are now sent to Cardie through an IM_ERROR message
(which appear in a BAlert), and an IM_PROTOCOL_DISABLED IM_MESSAGE is
sent to Cardie when the account is disabled/connection fails.
