Hinweise

Wenn die BehaviorService wird erstellt, es über den Designer Frame ein transparentes Fenster hinzugefügt.When the BehaviorService is created, it adds a transparent window over the designer frame. Die BehaviorService können Sie dieses Fenster zum Rendern der Elemente der Benutzeroberfläche, dem Namen Glyph Objekte sowie alle mausmeldungen.The BehaviorService can then use this window to render user interface elements, called Glyph objects, as well as catch all mouse messages. Auf diese Weise die BehaviorService können Designer Verhalten steuern.In this way, the BehaviorService can control designer behavior.

Die BehaviorService Klasse unterstützt eine Verhaltensstapels ab, auf dem Behavior Objekte abgelegt werden können.The BehaviorService class supports a behavior stack, onto which Behavior objects can be pushed. Wenn eine Nachricht über das Fenster "transparent" abgefangen wird die BehaviorService können sendet die Nachricht an die Behavior am Anfang des Stapels.When a message is intercepted through the transparent window, the BehaviorService can send the message to the Behavior at the top of the stack. Dadurch können andere Benutzeroberflächenmodi abhängig von der zurzeit mithilfe von Push übertragene Behavior.This enables different user interface modes depending on the currently pushed Behavior. Die BehaviorService wird verwendet, um alle Rendern Glyph Objekte, z. B. Markierungsrahmen, Ziehpunkte und Smarttags.The BehaviorService is used to render all Glyph objects, such as selection borders, sizing handles, and smart tags. Die BehaviorService steuert auch viele während der Entwurfszeit-Verhalten, wie Sie mithilfe von Ausrichtungslinien ziehen und Sie auswählen.The BehaviorService also controls many design-time behaviors, such as using snaplines, dragging, and selecting.
