| | 6 | <h2>Widget components</h2> |
| | 7 | <p>A widget component is a normal class which wraps the contents of a render method in a div or a span. Widget components sound more weighty then they are. They don't inherit from a standard component, but are it's brothers. Components which inherit from them inherit the slots css-class, css-style and css-id, which are used in the :wrapping method of a render method. For the interested: arnesi, on which ucw depends, utilizes define-method-combination for some extra method combo's. According to the source in /path/to/arnesi_dev/src/mop.lisp it allows a method to have the</p> |

| | 9 | "Same semantics as standard method combination but allows |
| | 10 | "wrapping" methods. Ordering of methods: |

| | 12 | <pre> |
| | 13 | (wrap-around |
| | 14 | (around |
| | 15 | (before) |
| | 16 | (wrapping |
| | 17 | (primary)) |
| | 18 | (after))) |
| | 19 | </pre> |
| | 20 | <pre> |
| | 21 | :warp-around, :around, :wrapping and :primary methods call the |
| | 22 | next least/most specific method via call-next-method (as in |
| | 23 | standard method combination). |

| | 25 | <p>There's not so much to them widget components. Defining them like this wraps it's content in a div with the attributes class, id and style:</p> |
| | 26 | <pre> |
| | 27 | (defclass widget-test (widget-component) |
| | 28 | () |
| | 29 | (:default-initargs :css-class '("bla" "blop") :css-id "widget-test" :css-style "font-size: 30pt; color: fuchsia")) |

| | 31 | <pre> |
| | 32 | (defmethod render ((comp widget-test)) |
| | 33 | (<:ah "bla")) |
| | 34 | </pre> |
| | 35 | <p>Let widget-test inherit from inline-widget-component instead to wrap your content in a span.</p> |
