我曾经在使用一个MXML类，但是因为我需要在构建时传递一些属性，为了更方便，我将它转换成AS3代码。

这个类是RectangleShape，它只是绘制一个矩形。

原始的mxml工作正常。

<?xml version="1.0" encoding="utf-8"?>
<BaseShape name="rectangle"
    xmlns="org.edorado.edoboard.view.components.shapes.*" 
    xmlns:mx="http://www.adobe.com/2006/mxml" 
    xmlns:degrafa="http://www.degrafa.com/2007"
    xmlns:objecthandles="com.roguedevelopment.objecthandles.*">

                this.width = movePt.x - this.x; 
                this.height = movePt.y - this.y;

我的 AS3 尝试

package org.edorado.edoboard.view.components.shapes { import com.degrafa.geometry.RegularRectangle; import com.degrafa.paint.SolidFill; import com.degrafa.paint.SolidStroke; import com.degrafa.GeometryGroup; import com.degrafa.Surface; import flash.geom.Point;

public class RectangleShape extends BaseShape 
{
    public var surface:Surface = new Surface(); 
    public var geoGroup:GeometryGroup = new GeometryGroup();
    public var solidFill:SolidFill = new SolidFill("white");
    public var solidStroke:SolidStroke = new SolidStroke("black");
    public var rect:RegularRectangle = new RegularRectangle(); 

    public static const name:String = "rectangle";

    public function RectangleShape() {
        addChild(surface);
        //surface.addChild(geoGroup);
        surface.graphicsCollection.addItem(geoGroup); 

        solidFill.alpha = 0.3;
        rect.fill = solidFill;
        rect.stroke = solidStroke;
        rect.width = this.width;
        rect.height = this.height;
        geoGroup.geometry = [rect];
        geoGroup.draw(null, null);

    override public function drag(movePt:Point):void {

        this.width = movePt.x - this.x; 
        this.height = movePt.y - this.y; 
        trace( dragging  , this.width, this.height);

问题是形状不再绘制了，BaseShape容器在那里，我可以看到跟踪的拖动正在工作，但不再有矩形。

Any obvious stuff i missed ? Thanks
