This content covers features introduced in Thunderbird 3

Implemented via XPCOM service for extIApplication: see the instructions on the FUEL (Firefox), STEEL (Thunderbird) and SMILE (SeaMonkey) pages.

Method overview

void addListener(in AString aEvent, in extIEventListener aListener)
void removeListener(in AString aEvent, in extIEventListener aListener)

Attributes

Attribute Type Description

Methods

addListener()

Adds an event listener to the list. If multiple identical event listeners are registered on the same event target with the same parameters the duplicate instances are discarded. They do not cause the EventListener to be called twice and since they are discarded they do not need to be removed with the removeListener method.

void addListener(in AString aEvent, in extIEventListener aListener)
Parameters
aEvent
The name of the event. A list of events is available here.
aListener
The event listener to be added
Return value

 

removeListener()

Removes an event listener from the list. Calling remove with arguments which do not identify any currently registered event listener has no effect.

void removeListener(in AString aEvent, in extIEventListener aListener)
Parameters
aEvent
The name of the event
aListener
The event listener to be removed
Return value
