예제

다음 예제에서는 처리를 FrameReported 이벤트에서 터치 데이터에 액세스 하 고는 TouchFrameEventArgs합니다.The following example handles the FrameReported event and accesses the touch data in the TouchFrameEventArgs. 터치를 눌렀음을 합니다 Canvas, TouchDevice 에 캡처되는지를 Canvas입니다.When a touch is pressed on the Canvas, the TouchDevice is captured to the Canvas. 터치 리프트 된 때를 TouchDevice 해제 됩니다.When the touch is lifted, the TouchDevice is released. 터치에서 이동 하는 경우는 Canvas, Id 확인란이 선택 되어 있습니다.When a touch moves across the Canvas, the Id is checked. 첫 번째 터치에서 이동 하는 경우, 해당 위치에 기록 됩니다.If the move came from the first touch, its location is recorded. 두 번째 터치에서 이동 하는 경우, 두 번째 터치 위치를 줄의 첫 번째 터치 위치에서 그려집니다.If the move came from the second touch, a line is drawn from the position of the first touch to the position of the second touch.

이 예제는에서 사용할 수 있는 보다 큰 예제의 일부는 Touch 클래스 개요입니다.This example is part of a larger example that is available in the Touch class overview.
