ShapeOrder: SpeedometerArrowCircleOrder;
The ShapeOrder property determines the order of circle positioning relative to arrow.
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;
CentralS: ISpeedometerCentralShape;
CentralSBack: ISpeedometerBackground;
Begin
s := SpeedometerBox1.Speedometer;
v := s.View;
s.BeginUpdate;
CentralS := v.CentralShape;
CentralSBack := CentralS.Background;
CentralSBack.Type :=SpeedometerBackgroundType.Gradient;
CentralSBack.Color :=GxColor.FromName("Red");
CentralSBack.GradientColor:= GxColor.FromName("Green");
CentralS.ShapeOrder :=SpeedometerArrowCircleOrder.BelowArrow;
CentralS.Radius := 0.7;
s.EndUpdate;
End Sub Button1OnClick;
If the user presses the button after executing this example, the design of the circle that is located in the centre of the SpeedometerBox1 speedometer component is set. The gradient filling of the background is set for the circle, and the circle is placed behind the speedometer arrow. Radius of the circle equals 0.7 of speedometer radius.
