GeometryHitTestResult(Visual, IntersectionDetail) 构造函数

定义

命名空间:

System.Windows.Media

程序集:

PresentationCore.dll

使用指定的可视对象和 GeometryHitTestResult 值初始化 IntersectionDetail 类的新实例。

public:
 GeometryHitTestResult(System::Windows::Media::Visual ^ visualHit, System::Windows::Media::IntersectionDetail intersectionDetail);

public GeometryHitTestResult (System.Windows.Media.Visual visualHit, System.Windows.Media.IntersectionDetail intersectionDetail);

new System.Windows.Media.GeometryHitTestResult : System.Windows.Media.Visual * System.Windows.Media.IntersectionDetail -> System.Windows.Media.GeometryHitTestResult

Public Sub New (visualHit As Visual, intersectionDetail As IntersectionDetail)

参数

visualHit

Visual

在命中测试期间命中的可视对象。

intersectionDetail

IntersectionDetail

描述 Geometry 和 visualHit 之间的交集。

示例

以下示例演示如何创建对象 GeometryHitTestResult 并将其用作重写实现的 HitTestCore返回值。

// Override default hit test support in visual object.
protected override GeometryHitTestResult HitTestCore(GeometryHitTestParameters hitTestParameters)
{
    IntersectionDetail intersectionDetail = IntersectionDetail.NotCalculated;

    // Perform custom actions during the hit test processing.

    return new GeometryHitTestResult(this, intersectionDetail);
}

' Override default hit test support in visual object.
Protected Overrides Overloads Function HitTestCore(ByVal hitTestParameters As GeometryHitTestParameters) As GeometryHitTestResult
    Dim intersectionDetail As IntersectionDetail = IntersectionDetail.NotCalculated

    ' Perform custom actions during the hit test processing.

    Return New GeometryHitTestResult(Me, intersectionDetail)
End Function
