Tunderbird

[Mario]

Hi all!

Is it possible to get the event if a mail has been received in thunderbird?

Thank you in advance for the answers.
Greetings Mario

Mario,

I have tried to get this in my ThunderbirdBiff addon. I could not find a
way to "hook" this. If you do, please let me know. Instead, I set up a
polling which iterates over the accounts and checks the biffState flag
of account's server. Not the same thing but it gets a similar result.

Check out an extension called Growl Notify or something like that. I
copied some code from it to listen for new messages. You basically need
to add a folder listener to some root folder.

I've added a listener to the MailSession and listen to the onItemAdded
event. Additionally, I make sure that the item added is indeed a new
message. It looks roughly like this:

OnItemAdded: function(parentItem, item, viewString) {
if (parentItem instanceof Components.interfaces.nsIMsgFolder) {
if (parentItem.flags & MSG_FOLDER_FLAG_INBOX) { // check inboxes only
if (item instanceof Components.interfaces.nsIMsgDBHdr) {
if (!item.isRead && (item.flags & 0x10000)) { // check new items
only
doSomething(item);
}
}
}
}
}

function register4MailEvents() {
var mailSession =
Components.classes["@mozilla.org/messenger/services/session;1"].getService(Components.interfaces.nsIMsgMailSession);
var notifyFlags = Components.interfaces.nsIFolderListener.added;
mailSession.AddFolderListener(spamatoFolderListener,notifyFlags);
}

Sorry, one part was missing, of course the OnItemAdded function must be
wrapped in the folderListener:

var folderListener = {
OnItemAdded: function(parentItem, item, viewString) {
...
}
}

function register4MailEvents() {
var mailSession =
Components.classes["@mozilla.org/messenger/services/session;1"].getService(Components.interfaces.nsIMsgMailSession);
var notifyFlags =
Components.interfaces.nsIFolderListener.added;

mailSession.AddFolderListener(folderListener,notifyFlags);
}

You can listen for mail:biff-state-changed observer notifications, but I
believe the facility has only recently been added so if you use that
technique your extension will only work in Thunderbird 2.

Alternatively, use a root folder listener, but listen for the integer
BiffState property; the value is 0 for new mail.

Neil,

Is there one root folder for the entire T-Bird or is there one per
account? In my extension, T-BirdBiff, I really only want to know if new
mail hass arrived - regardless of account or quantity. So if I only need
one listener for all accounts, that would be easier than sorting out
each account individually. Thanks for the tips.

The mail session collects all the notifications for all accounts. In
fact, the individual account listeners are not readily available from
JavaScript.
