Zusammenfassung: | A presenter system framework and methods performed by such framework are described for hosting a set of presenters that facilitate maintaining layouts for application views assigned a set of graphical elements. The presenter system provides a base presenter class and a set of interface methods, performed by a presentation engine, for creating and integrating an extensible set of presenter classes for handling various graphical element data types during a layout operation within a specified view. The presenter system enables application user interface developers to implement complex display layout operations through calls to the presentation engine. Examples of such complex display layout operations include: pagination, partial calculation, incremental calculation, multiple tries, chaining of layout features/operations.
Se describen un esquema del sistema presentador y metodos realizados a traves de dicho esquema para hospedar un grupo de presentadores que facilitan la manutencion de disenos para vistas de aplicacion asignadas a un grupo de elementos graficos. El sistema presentador proporciona una clase de presentador base y un grupo de metodos de interfase, realizados a traves de un procesador de presentacion, para crear e integrar un grupo extensible de clases de presentador para manejar varios tipos de datos del elemento grafico durante una operacion de diseno dentro de una vista especificada. El sistema presentador habilita a los desarrolladores de la interfase de usuario de aplicacion a implementar operaciones de diseno de despliegue complejas a traves de llamadas al procesador de presentacion. Ejemplos de dichas operaciones de diseno de despliegue complejas incluyen: paginacion, calculo parcial, calculo incremental, multiples intentos, encadenamiento de caracteristicas/operaciones de diseno. |
