实现
注解
此事件将为 Stylus.StylusDown 此类创建附加事件的别名，因此 StylusDown 当 ContentElement 继承为基元素时，它是类成员列表的一部分。This event creates an alias for the Stylus.StylusDown attached event for this class, so that StylusDown is part of the class members list when ContentElement is inherited as a base element. 附加到事件的事件处理程序 StylusDown 附加到基础 Stylus.StylusDown 附加事件，并接收相同的事件数据实例。Event handlers that are attached to the StylusDown event are attached to the underlying Stylus.StylusDown attached event and receive the same event data instance.
触摸、鼠标和触笔输入在特定关系中存在。Touch, mouse, and stylus input exist in a particular relationship. 有关详细信息，请参阅 输入概述。For more information, see Input Overview.
