Example

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;
    Back: ISpeedometerBackground;
Begin
    s := SpeedometerBox1.Speedometer;
    v := s.View;
    s.BeginUpdate;
    Back := v.Background;
    Back.Type := SpeedometerBackgroundType.Gradient;
    Back.Color := GxColor.FromName("Yellow");
    Back.GradientColor :=GxColor.FromName("Green");
    Back.GradientAngle :=45;
    s.EndUpdate;
End Sub Button1OnClick;

After executing the example, on clicking the button, formatting parameters of the speedometer displayed in the SpeedometerBox1 component are changed. The gradient fill is set for speedometer background.
