Значение свойства

Объект Visual, представляющий результат проверки нажатия.A Visual object that represents the hit test result.

Примеры

В следующем примере показано, как сослаться на значение VisualHit свойства в процедуру обратного вызова проверки попадания.The following example shows how to reference the value of the VisualHit property in a hit test callback procedure.

// 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
