ISpeedometerBar.StartColor

Syntax

StartColor: IGxColor;

Description

The StartColor property determines the start color of gradient filling of the segment.

Example

Executing this 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;

FilledBar: ISpeedometerFilledBar;

Bar, Bar1: ISpeedometerBar;

Begin

s := SpeedometerBox1.Speedometer;

v := s.View;

s.BeginUpdate;

ScaleView := s.View.ScaleViews.Item(0);

FilledBar := ScaleView.FilledBar;

FilledBar.StartRadius := 0.1;

FilledBar.EndRadius := 0.9;

FilledBar.Bars.Count := 2;

Bar := FilledBar.Bars.Item(0);

Bar1 := FilledBar.Bars.Item(1);

Bar.StartColor := GxColor.FromName("Blue");

Bar.EndColor := GxColor.FromName("Green");

Bar.Part := 0.7;

Bar1.StartColor := GxColor.FromName("Green");

Bar1.EndColor := GxColor.FromName("Red");

Bar1.Part := 0.3;

s.EndUpdate;

End Sub Button1OnClick;

If the user presses the button after executing this example, the design of speedometer color interval bar that is displayed in the SpeedometerBox1 component is changed. The interval bar is divided into two segments. Start and end color of gradient are determined for every segment. The first segment takes 70%, the second one - 30% of interval bar. Initial and final radius are set to 0,1 and 0,9, respectively.
