|---|
| cache | If a widget is generated dynamically via
'on-dispatch', and :no-cache isn't returned as the fourth
value, the widget is cached in this slot. This is done to
maintain the same instance of the generated widget accross
non-ajax requests. This slot contains nil (if no widget is
cached), or a cons pair with car containing a list of tokens
used to generate the widget, and cdr contains the widget
object. Accessors:dispatcher-cache. |
|---|---|
| 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. |
| current-pane-name | A name that identifies currently
selected entry. The selector widget should set
this slot every time a new widget is selected by
the user. Initargs::current-pane-name; Accessors:selector-mixin-current-pane-name. |
| dom-class | The DOM class (CSS class) of an
object. Set this to a string if you'd like to add an
additional CSS class to the ones generated from the class
hierarchy by default. Initargs::dom-class; Accessors:dom-class. |
| dom-id | The DOM id of an object. Can be a symbol, a
string or nil. When accessed through the 'dom-id' accessor,
will always become a string. Use ensure-dom-id or
widget-name (for widgets) to access its underlying
implementation. Initargs::dom-id. |
| on-dispatch | Must be bound to a function of two
arguments - (the dispatcher object, and a list of url
tokens). The function is expected to consume zero or
more tokens, and return three values - a widget that
represents a subset of the uri tokens, a list of
consumed uri tokens, and a list of remaining uri
tokens. If the widget cannot be instantiated, the
function should return nil. Note, it is necessary to
return both consumed and remaining tokens because the
function may want to return 'implicitly' consumed
tokens not present in the URL, (for example a url '/'
may really indicate default url '/employees'). This is
necessary to properly maintain
*current-navigation-url* in nested dispatcher
environments. Additionally, the function may return
different remaining tokens to modify the URL on the
fly. If the function returns a widget, the dispatcher
uses the widget to present the URL. Otherwise,
assummes the URL is invalid. This can be used for
wiki-style URLs, or any kind of custom
dispatching. Note, the returned widget will be cached
in 'dynamic-pane-cache'. To turn off caching the
widget, the function should return a fourth
value :no-cache. Initargs::on-dispatch; Accessors:dispatcher-on-dispatch. |
| panes | An association list of pane names (or
pane-info structures) and widgets. When a particular name is
selected, the corresponding widget should be rendered by the
selector widget. Initargs::panes; Accessors:selector-mixin-panes. |
| propagate-dirty | A list of widget paths (see
'find-widget-by-path') or widgets each of which
will be made dirty when this widget is made dirty
via a POST request. This slot allows setting up
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. |
| widget-prefix-fn | A function called prior to
rendering the widget body. The function should
expect the widget as well as any additional
arguments passed to the widget. Initargs::widget-prefix-fn; Accessors:widget-prefix-fn. |
| widget-suffix-fn | A function called after rendering
the widget body. The function should expect the
widget as well as any additional arguments passed
to the widget. Initargs::widget-suffix-fn; Accessors:widget-suffix-fn. |
| widgets-ephemeral-p | Whether widgets should be
considered to exist for certain only if in the
`dispatcher-cache'. When non-nil (the
default), `find-widget-by-path*' will only
follow paths through the cached widget. Initform:t, Initargs::widgets-ephemeral-p; Accessors:dispatcher-widgets-ephemeral-p. |
