In MXML, you define a LinearGradient by adding a series of GradientEntry objects, as the following example shows:

  <mx:fill>
  	<mx:LinearGradient>
  		<mx:entries>
  			<mx:GradientEntry color="0xC5C551" ratio="0.00" alpha="0.5"/>
  			<mx:GradientEntry color="0xFEFE24" ratio="0.33" alpha="0.5"/>
  			<mx:GradientEntry color="0xECEC21" ratio="0.66" alpha="0.5"/>
  		</mx:entries>
  	</mx:LinearGradient>
  </mx:fill>
  

You can also define a LinearGradient as a fill for any graphic element in ActionScript, as the following example shows:

  
  <?xml version="1.0"?>
  <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()">
  	<mx:Script>
  	import flash.display.Graphics;
  	import flash.geom.Rectangle;
  	import mx.graphics.GradientEntry;
  	import mx.graphics.LinearGradient;
  
  	private function init():void
      {
  		var w:Number = 200;
  		var h:Number = 200;
  
  		var s:Sprite = new Sprite();
  		// Add the new Sprite to the display list.
  		rawChildren.addChild(s);	
  
  		var g:Graphics = s.graphics;
  		g.lineStyle(1, 0x33CCFF, 1.0);
  
  		var fill:LinearGradient = new LinearGradient();
  		
  		var g1:GradientEntry = new GradientEntry(0xFFCC66, 0.00, 0.5);
  		var g2:GradientEntry = new GradientEntry(0x000000, 0.33, 0.5);
  		var g3:GradientEntry = new GradientEntry(0x99FF33, 0.66, 0.5);
    		
   		fill.entries = [ g1, g2, g3 ];
  		fill.angle = 240;
  
   		// Draw a box and fill it with the LinearGradient.
  		g.moveTo(0, 0);
  		fill.begin(g, new Rectangle(0, 0, w, h));
  		g.lineTo(w, 0);
  		g.lineTo(w, h);
  		g.lineTo(0, h);
  		g.lineTo(0, 0);		
  		fill.end(g);
  	}
  	</mx:Script>
  </mx:Application>
