package {

 import flash.display.GradientType;
 import flash.display.Sprite;
 import flash.geom.Matrix;
      
 public class Main extends Sprite {
 
      public function Main() {
         graphics.lineStyle(1);

Draws a red triangle with a five pixel-thick black outline. Notice that the default start point matches the endpoint

package{

 import flash.display.*;
 
 public class Main extends Sprite{
   public function Main(){
       var triangle:Shape = new Shape(  );
       triangle.graphics.beginFill(0xFF0000, 1);
       triangle.graphics.lineStyle(20);
       triangle.graphics.lineTo(125, 125); // Draw a line down and right
       triangle.graphics.lineTo(250, 0);   // Draw a line up and right
       triangle.graphics.lineTo(0, 0);     // Draw a line left

MouseEvent.MOUSE_MOVE: Handling MouseEvent.MOUSE_MOVE over a triangle

   <source lang="java">

package {

     // Create the triangle

Registers mouseMoveListener( ) to be executed whenever the mouse moves while the mouse pointer is over the Sprite object referenced by the variable triangle.
