title: Event Mechanism
|
|
|
|
Most of the following mechanisms need a way to get notified, when anything in the wiki store changes.
|
|
The core -plug-in adds an event system to the bare wiki store.
|
|
The event system provides the ability to listen to events. The most important is the "change" event which notifies the listeners when tiddlers have changed, with a list of the changed tiddlers.
|
|
The event mechanism is one of the few mechanisms which needs a hook at the microkernel:
|
|
The microkernel contains an empty function "enqueueTiddlerEvent(event)" and calls this function when a tiddler is added or deleted.
|
|
The event mechanism from the core plug-in overwrites this function with it's own implementation.
|
|
The functions providing the event system are added via the [[wikimethod module type]]. |
