|
|
* A unique ID that identifies the type of notification (e.g.

|

* anchored to the iconBox.
|
|
* @param mainAction
|
|
* A JavaScript object literal describing the notification button's
|
|
* action. If present, it must have the following properties:
|
|
* - label (string): the button's label.
|
|
* - accessKey (string): the button's accessKey.

* - callback (function): a callback to be invoked when the button is

|
* pressed.
|
|
* If null, the notification will not have a button, and
|
|
* secondaryActions will be ignored.
|
|
* @param secondaryActions
|
|
* An optional JavaScript array describing the notification's alternate
|
|
* actions. The array should contain objects with the same properties
|
|
* as mainAction. These are used to populate the notification button's
|
|
* dropdown menu.
|
|
* @param options
|
|
* An options JavaScript object holding additional properties for the
|
|
* notification. The following properties are currently supported:
|
|
* persistence: An integer. The notification will not automatically
|
|
* dismiss for this many page loads.
|
|
* timeout: A time in milliseconds. The notification will not
|
|
* automatically dismiss before this time.
|
|
* persistWhileVisible:
|
|
* A boolean. If true, a visible notification will always
|
|
* persist across location changes.
|
|
* dismissed: Whether the notification should be added as a dismissed
|
|
* notification. Dismissed notifications can be activated
|
|
* by clicking on their anchorElement.
|
|
* eventCallback:
|
|
* Callback to be invoked when the notification changes
|
|
* state. The callback's first argument is a string
|
|
* identifying the state change:
|
|
* "dismissed": notification has been dismissed by the
|
|
* user (e.g. by clicking away or switching
|
|
* tabs)
|
|
* "removed": notification has been removed (due to
|
|
* location change or user action)
|
|
* "shown": notification has been shown (this can be fired
|
|
* multiple times as notifications are dismissed
|
|
* and re-shown)
|
|
* neverShow: Indicate that no popup should be shown for this
|
|
* notification. Useful for just showing the anchor icon.
|
|
* removeOnDismissal:
|
|
* Notifications with this parameter set to true will be
|
|
* removed when they would have otherwise been dismissed
|
|
* (i.e. any time the popup is closed due to user
|
|
* interaction).
|
|
* @returns the Notification object corresponding to the added notification.
