BehaviorService Cuando se crea, agrega una ventana transparente sobre el marco del diseñador.When the BehaviorService is created, it adds a transparent window over the designer frame. A continuación, Glyph puedeutilizarestaventanapararepresentarloselementosdelainterfazdeusuario,denominadosobjetos,asícomoparadetectartodoslosBehaviorService mensajes del mouse.The BehaviorService can then use this window to render user interface elements, called Glyph objects, as well as catch all mouse messages. De esta manera, puede BehaviorService controlar el comportamiento del diseñador.In this way, the BehaviorService can control designer behavior.

La BehaviorService clase admite una pila de comportamientos, en Behavior la que se pueden insertar objetos.The BehaviorService class supports a behavior stack, onto which Behavior objects can be pushed. Cuando un mensaje se intercepta a través de la ventana transparente, BehaviorService puede enviar el mensaje Behavior a en la parte superior de la pila.When a message is intercepted through the transparent window, the BehaviorService can send the message to the Behavior at the top of the stack. Esto permite diferentes modos de interfaz de usuario en función de los Behaviorinsertados actualmente.This enables different user interface modes depending on the currently pushed Behavior. Se utiliza para representar todos los Glyph objetos, como los bordes de selección, los controladores de tamaño y las etiquetas inteligentes. BehaviorServiceThe BehaviorService is used to render all Glyph objects, such as selection borders, sizing handles, and smart tags. También BehaviorService controla muchos comportamientos en tiempo de diseño, como el uso de las líneas de ajuste, el arrastre y la selección.The BehaviorService also controls many design-time behaviors, such as using snaplines, dragging, and selecting.
