Widget messages are generated by widgets in response to user actions. They flow up the widget tree until they are handled by an ancestor widget.
|
||||
|
||||
The following widget messages are implemented by the core:
|
||||
|
||||
<ul>
|
||||
<$list filter="[tag[message]]">
|
||||
<li>
|
||||
<$link to={{!!title}}>

<$view field="title"/>

The key to understanding how it works internally is to see that the RefreshMechanism requires that any region of the DOM can be regenerated at any time. This means that the entire state of the user interface must reside in the tiddler store, and not in the DOM.

The key to understanding how it works internally is to see that the RefreshMechanism requires that any region of the DOM can be regenerated at any time. This means that the entire state of the user interface must reside in the tiddler store, from where it is synchronised into the DOM. This is done to improve performance by minimising the DOM interactions during the refresh cycles.
