Примеры

В следующем примере показано, как использовать IntersectionDetail свойство GeometryHitTestResult.The following example shows how to use the IntersectionDetail property of GeometryHitTestResult.

// 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

Комментарии

IntersectionDetail Свойство описывает пересечение между Geometry и целевого визуального объекта.The IntersectionDetail property describes the intersection between a Geometry and the target visual object.

Ниже показана связь между геометрию проверки нажатия (синий круг) и целевого объекта (красный квадрат).The following illustration shows the relationship between the hit test geometry (the blue circle) and the target object (the red square).
