備註
BehaviorService建立 時,它會在設計工具框架上新增透明視窗。 BehaviorService接著,可以使用這個視窗來轉譯使用者介面元素,稱為 Glyph 物件,以及攔截所有滑鼠訊息。 如此一來, BehaviorService 就可以控制設計工具的行為。
類別 BehaviorService 支援可推送對象的行為堆疊 Behavior 。 透過透明視窗攔截訊息時, BehaviorService 可以將訊息傳送至 Behavior 堆疊頂端的 。 這會根據目前推送 Behavior的 來啟用不同的使用者介面模式。 BehaviorService用來轉譯所有Glyph物件,例如選取框線、重設大小控點和智慧標記。 也會 BehaviorService 控制許多設計時間行為,例如使用貼齊線、拖曳和選取。
如需詳細資訊,請參閱 行為服務概觀。
