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.
