Possible to create notification?

[CaptainBlagbird]

Is it possible to create a chat window notification (speech bubble symbol near number of online friends)?

AFAIK there are 3 options to notify the user about something:

• System message in chat
• Custom UI element
• Sound

It's not possible to send a mail to self (probably so ppl can't temp-store items when their inventory is full), but would be useful for longer add-on notifications without having to create a custom UI.

But maybe it is possible to create a notification? If so, how? If not, would it be possible to "fake" it (something like this: playing sound + changing the variable that stores the number of notifications + adding element to the table with the pending notifications)?

It is possible to add your own notifications provider in order to fake a notification.

I have played around with it a bit in the past, and managed to make a notification with accept and decline button.
The gist of it is that you need to subclass ZO_NotificationProvider and overwrite all the necessary methods.
I am not sure if this code still works, but maybe you can use it as a starting point:

local MyNotificationProvider = ZO_NotificationProvider:Subclass()
function MyNotificationProvider:New(notificationManager)
    local provider = ZO_NotificationProvider.New(self, notificationManager)
    provider.nextId = 1
    return provider
end
 
function MyNotificationProvider:GetNextId()
    local id = self.nextId
    self.nextId = id + 1
    return id
end
 
function MyNotificationProvider:AddNotification(data)
    if(data.id == nil) then
        local list = self.list
        data.id = self:GetNextId()
        list[data.id] = data
    else
        d("Cannot add a notification with an existing id.")
    end
end
 
function MyNotificationProvider:RemoveNotification(id)
    self.list[id] = nil
end
 
function MyNotificationProvider:Accept(data)
    self:RemoveNotification(data.id)
end
 
function MyNotificationProvider:Decline(data)
    self:RemoveNotification(data.id)
end
 
local myProvider = MyNotificationProvider:New(NOTIFICATIONS)
table.insert(NOTIFICATIONS.providers, myProvider)
 
myProvider:AddNotification( {
    "Hello World!"
    })

Thanks, this helped a lot!

Your example doesn't work anymore though. I managed to get this minimalistic example to work so far (only one notification handled etc.):

local MyNotificationProvider = ZO_NotificationProvider:Subclass()
function MyNotificationProvider:New(notificationManager)
    return ZO_NotificationProvider.New(self, notificationManager)
end
 
function MyNotificationProvider:RemoveNotification()
    ZO_ClearNumericallyIndexedTable(self.list)
    self:PushUpdateToNotificationManager()
end
 
function MyNotificationProvider:AddNotification(data)
    self.list[1] = data
    self:PushUpdateToNotificationManager()
 
    if data.notificationType == nil then
        ZO_NotificationsList1Row1Icon:SetTexture("EsoUI/Art/MainMenu/menuBar_notifications_down.dds")
        ZO_NotificationsList1Row1Type:SetText("Notification")
    end
end
 
function MyNotificationProvider:Accept()
    self:RemoveNotification()
    d("Accepted")
end
 
function MyNotificationProvider:Decline()
    self:RemoveNotification()
    d("Declined")
end
 
myProvider = MyNotificationProvider:New(NOTIFICATIONS)
table.insert(NOTIFICATIONS.providers, myProvider)
 
 
-- Later, e.g. with /script
myProvider:AddNotification({
            notificationType = NOTIFICATION_TYPE_TRADE, -- Icon & title
            dataType = NOTIFICATIONS_REQUEST_DATA,      -- Buttons / waiting symbol / note symbol
            note = "note",                              -- Note on hover over note symbol
            message = "message",                        -- Main message
            -- controlsOwnSounds = true,                -- true: No sound
        })

Here you go, try this. I didn't test it very much, but it seemed to work fine. If you run into any problems let me know & I'll fix it.

LibNotifications

And P.S. there is also ZO_Alert() to display alert messages in the upper right hand corner:

ZO_Alert(UI_ALERT_CATEGORY_ERROR, SOUNDS.NEGATIVE_CLICK, "some message")

Awesome thanks!

That's what I wanted to do eventually (after having a stable example and learning how to create a library )
