BehaviorServiceが作成されると、デザイナーフレーム上に透明なウィンドウが追加されます。When the BehaviorService is created, it adds a transparent window over the designer frame. BehaviorServiceに、このウィンドウを使用して、オブジェクトと呼ばGlyphれるユーザーインターフェイス要素を表示したり、すべてのマウスメッセージをキャッチしたりできます。The BehaviorService can then use this window to render user interface elements, called Glyph objects, as well as catch all mouse messages. このようにしてBehaviorService 、はデザイナーの動作を制御できます。In this way, the BehaviorService can control designer behavior.

クラスBehaviorServiceは、 Behaviorオブジェクトをプッシュできる動作スタックをサポートしています。The BehaviorService class supports a behavior stack, onto which Behavior objects can be pushed. メッセージが透明なウィンドウを介して傍受されるBehaviorServiceと、は、スタックのBehavior一番上にあるにメッセージを送信できます。When a message is intercepted through the transparent window, the BehaviorService can send the message to the Behavior at the top of the stack. これにより、現在プッシュBehaviorされているに応じて、さまざまなユーザーインターフェイスモードが有効になります。This enables different user interface modes depending on the currently pushed Behavior. BehaviorService 、選択境界、サイズGlyph変更ハンドル、スマートタグなど、すべてのオブジェクトを表示するために使用されます。The BehaviorService is used to render all Glyph objects, such as selection borders, sizing handles, and smart tags. またBehaviorService 、は、スナップ線の使用、ドラッグ、選択など、さまざまなデザイン時の動作を制御します。The BehaviorService also controls many design-time behaviors, such as using snaplines, dragging, and selecting.
