We have bedroom, bathroom, classroom and boardroom as one word. Living room is spelled separately because of the present participle (+ing) in living. With "chatbox" it's a bit more subjective. We have chatbot as one word (but litter box as two). For consistency with chatroom, I'll go with one word.

|
|
Events and promises
|
|
===================
|
|
|
|
Converse.js and its plugins emit various events which you can listen to via the
|
|
:ref:`listen-grouping`.
|
|
|
|
Some of these events are also available as `ES2015 Promises <http://es6-features.org/#PromiseUsage>`_,
|
|
although not all of them could logically act as promises, since some events
|
|
might be fired multpile times whereas promises are to be resolved (or
|
|
rejected) only once.
|
|
|
|
The core events, which are also promises are:
|
|
|
|
* `cachedRoster`_
|
|
* `chatBoxesFetched`_
|
|
* `controlboxInitialized`_ (only via the `converse-controlbox` plugin)
|
|
* `pluginsInitialized`_
|
|
* `roomsPanelRendered`_ (only via the `converse-muc` plugin)
|
|
* `rosterContactsFetched`_
|
|
* `rosterGroupsFetched`_
|
|
* `rosterInitialized`_
|
|
* `roster`_
|
|
* `statusInitialized`_
|
|
|
|
For more info on how to use (or add promises), you can read the
|
|
:ref:`promises-grouping` in the API documentation.
|
|
|
|
Below we will now list all events and also specify whether they are available
|
|
as promises.
|
|
|
|
List of Events (and promises)
|
|
-----------------------------
|
|
|
|
Hooking into events that Converse.js emits is a great way to extend or
|
|
customize its functionality.
|
|
|
|
From version 3.0.0 and up, it's only possible to register event handlers inside
|
|
a plugin, by using the closured ``_converse`` object. When writing a plugin,
|
|
remember that it will also have to be whitelisted, before it will be loaded.
|
|
Refer to the :ref:`whitelisted_plugins` setting.
|
|
|
|
Here follows the different events that are emitted:
|
|
|
|
afterMessagesFetched
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Emitted whenever a chatbox has fetched its messages from ``sessionStorage`` and
|
|
**NOT** from the server.
|
|
|
|
This event is listened to by the ``converse-mam`` plugin to know when it can
|
|
fetch archived messages from the server.
|
|
|
|
The event handler is passed the ``Backbone.View`` instance of the relevant chat
|
|
box.
|
|
|
|
``_converse.on('afterMessagesFetched', function (chatboxview) { ... });``
|
|
|
|
.. _`cachedRoster`:
|
|
|
|
cachedRoster
|
|
~~~~~~~~~~~~
|
|
|
|
The contacts roster has been retrieved from the local cache (`sessionStorage`).
|
|
|
|
``_converse.on('cachedRoster', function (items) { ... });``
|
|
|
|
Also available as an `ES2015 Promise <http://es6-features.org/#PromiseUsage>`_:
|
|
|
|
.. code-block:: javascript
|
|
|
|
_converse.api.waitUntil('cachedRoster').then(function () {
|
|
// Your code here...
|
|
});
|
|
|
|
See also the `roster`_ event further down.

|
|
~~~~~~~~~~~~~~~~
|

|
``_converse.on('chatBoxesFetched', function (items) { ... });``
