TDesignerLayer32.DrawQSplineDesign

procedure DrawQSplineDesign(const ctrlPts: TArrayOfPointD; isStartOfPath: Boolean = true);

Using the supplied Quadratic Bezier spline coordinates, this method draws a dashed line connecting all control points (including implicit control points) to their end points. It also draws implicit buttons (see the clear buttons in the image below), buttons representing implicit spline coordinates (in distinction to explicit ones). Explicit coordinate buttons are presumably being managed by the library user in their own separate layers (see also CreateButtonGroup).
