Events

There are a lot of events that can be fired in Mail code. Some of these are standard events, such as those created by the DOM. Others are internal to Gecko or other parts of Mozilla application code. This reference will help you track those events down and learn how to use them.

Composition

Event Name Event Type Fired when...
compose-send-message A message gets sent
compose-window-close A compose window gets closed
compose-window-init A compose window has been opened
compose-window-reopen A cached compose window has been reopened. No load event is fired in this case.
