/** |
| 21 |
* Register a server-side desktop widget. Symmetric to |
| 22 |
* {@see desktop_mode_register_window()} for the right-column widget |
| 23 |
* layer: plugin declares the widget's metadata + script handle in |
| 24 |
* PHP; shell syncs its registry from the live payload so |
| 25 |
* activation / deactivation map to picker add / remove without a |
| 26 |
* browser reload. |
| 27 |
* |
| 28 |
* The mount callback still lives in JS — not serializable across |
| 29 |
* the wire. Plugins register it on |
| 30 |
* `window.desktopModeWidgets[ <id> ]` as a `(container, ctx) => |
| 31 |
* teardown` function. The shell reads that global once the |
| 32 |
* declared script loads and wraps it into a WidgetDef. |
| 33 |
* |
| 34 |
* Example: |
| 35 |
* |
| 36 |
* ```php |
| 37 |
* desktop_mode_register_widget( 'myplugin/stats', array( |
| 38 |
* 'label' => __( 'Stats', 'my-plugin' ), |
| 39 |
* 'description' => __( 'Live analytics rollup', 'my-plugin' ), |
| 40 |
* 'icon' => 'dashicons-chart-bar', |
| 41 |
* 'script' => 'my-plugin-desktop-widgets', |
| 42 |
* 'movable' => true, |
| 43 |
* 'resizable' => true, |
| 44 |
* 'default_width' => 280, |
| 45 |
* 'default_height' => 180, |
| 46 |
* ) ); |
| 47 |
* ``` |
| 48 |
* |
| 49 |
* ```js |
| 50 |
* // Inside my-plugin-desktop-widgets.js: |
| 51 |
* window.desktopModeWidgets = window.desktopModeWidgets || {}; |
| 52 |
* window.desktopModeWidgets[ 'myplugin/stats' ] = function ( container, ctx ) { |
| 53 |
* container.append( buildDOM() ); |
| 54 |
* return function teardown() { }; |
| 55 |
* }; |
| 56 |
* ``` |
| 57 |
* |
| 58 |

| 60 |
* silent `false`. Legacy `if ( $result )` callers remain |
| 61 |
* correct because `WP_Error` is truthy. |
| 62 |
* |
