Beispiele

Das folgende Beispiel zeigt, wie Sie die Unterstützung des Standardmäßigen Treffertests in einem benutzerdefinierten visuellen Objekt außer Kraft setzen. In diesem Fall wird der HitPoint Wert einfach als Teil von PointHitTestResult.

// 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
