Drawing application

1

hi everyone

right now i’m making the drawing application for flash cs3

this is the sample of my class

package {
import flash.display.Shape;
import flash.display.Sprite;
import flash.events.MouseEvent;

public class DrawPathExample extends Sprite {
	private var _xPos:Number = 0;
	private var _yPos:Number = 0;
	var line:Shape =new Shape();
	//var button_btn = new button_clear();


	public function DrawPathExample() {
		stage.addEventListener(MouseEvent.MOUSE_DOWN, startDraw);
		//button.addEventListener(MouseEvent.CLICK, eraseDraw);
	}
	private function startDraw(event:MouseEvent):void {
		stage.removeEventListener(MouseEvent.MOUSE_DOWN, startDraw);
		stage.addEventListener(MouseEvent.MOUSE_UP, doneDraw);
		_xPos = mouseX;
		_yPos = mouseY;
		stage.addEventListener(MouseEvent.MOUSE_MOVE, tempDraw);
	}
	private function tempDraw(event:MouseEvent):void {
		addChild(line);
		line.graphics.clear();
		line.graphics.lineStyle(1,0xFF0000,0.5);
		line.graphics.moveTo(_xPos, _yPos);
		line.graphics.lineTo(mouseX, mouseY);
		event.updateAfterEvent();
	}
	private function doneDraw(event:MouseEvent):void {
		removeChild(line);
		stage.removeEventListener(MouseEvent.MOUSE_MOVE, tempDraw);
		stage.removeEventListener(MouseEvent.MOUSE_UP, doneDraw);
		stage.addEventListener(MouseEvent.MOUSE_DOWN, startDraw);
		graphics.lineStyle(3,0xFF0000,1);
		graphics.moveTo(_xPos, _yPos);
		graphics.lineTo(mouseX, mouseY);
	}
	private function eraseDraw(event:MouseEvent):void
	{
		graphics.clear();
	}
}

}

the problem is i can’t figure it out how to make his program draw and fill the color inside the close shape.

i would like to have the beginning of next line is the the end of last line until the shape is close and fill the color inside it.

sorry for poor english. English is not my main language

thanks everyone i will try to figure it out more. if anybody could help that would be nice
