| 21 |
|
|
* |
| 22 |
|
|
* These components could be something which make up |
| 23 |
|
|
* parts, areas or pages on a large website (the level above |
| 24 |
|
|
* the widget-layer) or just simple plugins or shared code. |
| 25 |
|
|
* (similar to m$'s dll/com-system, but very lightweight) |
| 26 |
|
|
* |
| 27 |
|
|
* Currently, we are registering "Views" with this thing. |
| 28 |
|
|
* These "Views" should represent the "Views" in the MVC Model. |
| 29 |
|
|
* "Views" are components made up of phpHtmlLib widgets. |
| 30 |
|
|
* |
| 31 |
|
|
* They currently live in the "Page::" namespace, which should be |
| 32 |
|
|
* migrated to the "View::" namespace to actually represent this |
| 33 |
|
|
* stuff conveniently 1:1 in userspace. |
