IntersectionDetail

적중 횟수 테스트의 IntersectionDetail 값입니다.

예제

다음 예제에서는 사용 하는 방법을 보여 줍니다 합니다 IntersectionDetail 속성의 GeometryHitTestResult합니다.

// Return the result of the hit test to the callback.
public HitTestResultBehavior MyHitTestResultCallback(HitTestResult result)
{
    // Retrieve the results of the hit test.
    IntersectionDetail intersectionDetail = ((GeometryHitTestResult)result).IntersectionDetail;

    switch (intersectionDetail)
    {
        case IntersectionDetail.FullyContains:

            // Add the hit test result to the list that will be processed after the enumeration.
            hitResultsList.Add(result.VisualHit);

            return HitTestResultBehavior.Continue;

        case IntersectionDetail.Intersects:

            // Set the behavior to return visuals at all z-order levels.
            return HitTestResultBehavior.Continue;

        case IntersectionDetail.FullyInside:

            // Set the behavior to return visuals at all z-order levels.
            return HitTestResultBehavior.Continue;

        default:
            return HitTestResultBehavior.Stop;
    }
}

' Return the result of the hit test to the callback.
Public Function MyHitTestResultCallback(ByVal result As HitTestResult) As HitTestResultBehavior
    ' Retrieve the results of the hit test.
    Dim intersectionDetail As IntersectionDetail = (CType(result, GeometryHitTestResult)).IntersectionDetail

    Select Case intersectionDetail
        Case IntersectionDetail.FullyContains

            ' Add the hit test result to the list that will be processed after the enumeration.
            hitResultsList.Add(result.VisualHit)

            Return HitTestResultBehavior.Continue

        Case IntersectionDetail.Intersects

            ' Set the behavior to return visuals at all z-order levels.
            Return HitTestResultBehavior.Continue

        Case IntersectionDetail.FullyInside

            ' Set the behavior to return visuals at all z-order levels.
            Return HitTestResultBehavior.Continue

        Case Else
            Return HitTestResultBehavior.Stop
    End Select
End Function
