PointHitTestParameters.HitPoint 属性

定义

命名空间:

System.Windows.Media

程序集:

PresentationCore.dll

获取要对其进行命中测试的 Point。

public:
 property System::Windows::Point HitPoint { System::Windows::Point get(); };

public System.Windows.Point HitPoint { get; }

member this.HitPoint : System.Windows.Point

Public ReadOnly Property HitPoint As Point

属性值

Point

要对其进行命中测试的 Point。

示例

以下示例演示如何在用户定义的视觉对象中替代默认命中测试支持。 在这种情况下， HitPoint 值只是作为其中的 PointHitTestResult一部分返回的。

// Override default hit test support in visual object.
protected override HitTestResult HitTestCore(PointHitTestParameters hitTestParameters)
{
    Point pt = hitTestParameters.HitPoint;

    // Perform custom actions during the hit test processing,
    // which may include verifying that the point actually
    // falls within the rendered content of the visual.

    // Return hit on bounding rectangle of visual object.
    return new PointHitTestResult(this, pt);
}

' Override default hit test support in visual object.
Protected Overrides Overloads Function HitTestCore(ByVal hitTestParameters As PointHitTestParameters) As HitTestResult
    Dim pt As Point = hitTestParameters.HitPoint

    ' Perform custom actions during the hit test processing,
    ' which may include verifying that the point actually
    ' falls within the rendered content of the visual.

    ' Return hit on bounding rectangle of visual object.
    Return New PointHitTestResult(Me, pt)
End Function
