Exemplos

O exemplo a seguir mostra como substituir o suporte padrão de teste de clique em um objeto visual definido pelo usuário. Nesse caso, um novo PointHitTestResult é criado e retornado do método substituído.

// 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
