Executing the example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

s: ISpeedometer;

v: ISpeedometerView;

ScaleView: ISpeedometerScaleView;

ArrowView: ISpeedometerArrowView;

Begin

s := SpeedometerBox1.Speedometer;

v := s.View;

s.BeginUpdate;

ScaleView := v.ScaleViews.Item(0);

ArrowView := ScaleView.ArrowViews.Item(0);

ArrowView.AxisOffset := 0.1;

ArrowView.Background.Color := GxColor.FromName("Green");

ArrowView.Length := 0.8;

ArrowView.Shape := SpeedometerArrowShapes.Triangle;

ArrowView.Width := 0.15;

s.EndUpdate;

End Sub Button1OnClick;
