7 * This header file lists up all event messages.
8 * Before including this header file, you should define:
9 * NS_EVENT_MESSAGE(aMessage)
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.
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".
