widget | Base class for all widget objects. |
---|
continuation | Stores the continuation object for
widgets that were invoked via one of the do-*
functions ('do-page', etc.). When 'answer' is called
on a widget, this value is used to resume the
computation. Accessors:widget-continuation. |
---|---|
messages | A list of messages to be rendered the
next time the widget is to be presented. This can be any
renderable object (a widget, a function, a string,
etc.) Initargs::messages; Accessors:flash-messages. |
name | A name of the widget used in rendering CSS
classes. If the name is not provided it will be generated
automatically with 'generate-widget-id'. Initform:(generate-widget-id), Initargs::name; Accessors:widget-name. |
old-messages | A list of messages from the previous
request. Initargs::messages; Accessors:flash-old-messages. |
propagate-dirty | A list of widget paths (see
'find-widget-by-path') or widgets each of which

dependencies between widgets that will make
multiple widgets update automatically during AJAX
requests. Initargs::propagate-dirty; Accessors:widget-propagate-dirty. |
renderedp | This slot holds a boolean flag
indicating whether the widget has been rendered at least
once. Because marking unrendered widgets as dirty may
cause JS problems, 'mark-dirty' will use this flag to
determine the status of a widget. Accessors:widget-rendered-p. |

expect the widget as well as any additional
arguments passed to the widget. Initargs::widget-prefix-fn; Accessors:widget-prefix-fn. |
