   7  * This header file lists up all event messages.
   8  * Before including this header file, you should define:
   9  * NS_EVENT_MESSAGE(aMessage)
  10  *
  11  * Additionally, you can specify following macro for e*First and e*Last.
  12  * NS_EVENT_MESSAGE_FIRST_LAST(aMessage, aFirst, aLast)
  13  * This is optional, if you need only actual event messages, you don't need
  14  * to define this macro.
  15  *
  16  * Naming rules of the event messages:
  17  * 0. Starting with "e" prefix and use camelcase.
  18  * 1. Basically, use same name as the DOM name which is fired at dispatching
  19  *    the event.
  20  * 2. If the event message name becomes too generic, e.g., "eInvalid", that may
  21  *    conflict with another enum's item name, append something after the "e"
  22  *    prefix, e.g., "eFormInvalid".
