| /** |
| * |
| * OODT Balance |
| * Web Application Base Framework |
| * |
| * Interface for developing widgets (reusable bits of view code) that can |
| * be placed on different application pages. |
| * |
| * This interface defines two mandatory functions: |
| * - construct : Intialize the widget and provide any necessary |
| * configuration information |
| * - render : Build the HTML output that constitutes the widget. This |
| * function does not accept arguments (any config should |
| * be provided either in the controller or via other "set" |
| * functions. This function should return a string composed |
| * of the final HTML output of the widget. |
| * |
| * Framework widgets can be found inside the {LIB}/scripts/widgets directory. |
| * |
| * Framework Widgets can be invoked from view code as follows: |
| * // Create an instance of the widget (will transparently call __construct) |
| * $myFooWidget = $app->createWidget('FooWidget',array(..config..)) |
| * |
| * Custom widgets should be placed inside the {HOME}/scripts/widgets directory and |
| * can be named FooWidget.php. All widgets must implement this interface. |
| * |
| * Custom Widgets can be invoked from view code as follows: |
| * // Create an instance of the widget (will transparently call __construct) |
| * $myFooWidget = $app->createWidget('FooWidget',array(..config..),true) // true --> custom |
| * |
| * <!-- (all widgets, framework or custom): display widget contents --> |
| * <span><?php echo $myFooWidget->render()?></span> |
