ISpeedometerView.Background

Syntax

Background: ISpeedometerBackground;

Description

The Background property determines parameters of speedometer background displaying.

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.GradientAngle := 45;

Back.GradientColor := GxColor.FromName("Red");

v.BottomMargin := 0.1;

v.LeftMargin := 0.1;

v.RightMargin := 0.1;

v.TopMargin := 0.1;

s.EndUpdate;

End Sub Button1OnClick;

After executing the example, on clicking the button, the formatting parameters of the speedometer displayed in the SpeedometerBox1 component are changed. The gradient background and margins from the component sides to speedometer sides are set.
