Flex的MXML来AS3,小班我错过了什么?

我使用MXML类但因为我需要通过在构造时的一些性质,以使其更易于我将其转换为AS3代码。
类是RectangleShape,它只是绘制一个矩形。
<强>原始MXML工作强>
<?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.*">
<mx:Script>
<![CDATA[
import org.edorado.edoboard.view.components.shapes.IShape;
import mx.events.FlexEvent;
override public function drag(movePt:Point):void {
this.width = movePt.x - this.x;
this.height = movePt.y - this.y;
}
override public function updateFillColor(color:int):void {
solidFill.color = color;
}
]]>
</mx:Script>
<degrafa:Surface >
<degrafa:GeometryGroup id="geo">

<degrafa:SolidFill id="solidFill" color="white" alpha="0.3"/>
</degrafa:fills>

<degrafa:SolidStroke id="stroke1" color="white"/>
</degrafa:strokes>
<degrafa:RegularRectangle
id="rect"
fill = "{solidFill}"
width="{width}"
height="{height}"
stroke="{stroke1}" />
</degrafa:GeometryGroup>
</degrafa:Surface>
</BaseShape>
我试图AS3 强>
包org.edorado.edoboard.view.components.shapes { 进口com.degrafa.geometry.RegularRectangle; 进口com.degrafa.paint.SolidFill; 进口com.degrafa.paint.SolidStroke; 进口com.degrafa.GeometryGroup; 进口com.degrafa.Surface; 进口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);
}
override public function updateFillColor(color:int):void {
solidFill.color = color;
}
}
}
的问题是,形状并不绘制了,该容器BaseShape是存在的,我可以看到的跟踪拖动工作,但不是矩形了。
任何明显的东西我错过? 感谢
解决方案
尝试用BindingUtils类建立绑定。
例如:
BindingUtils.bindProperty(component, "height", this, "height");
其他提示
我想我精确定位的问题。 之前在MXML版本中,我们有
宽度= “{}宽度” 高度= “{}高度”
和所述degrafa矩形将自动适应它的父。
,但不是在AS版本。我应该尝试重现中作为{宽度}和{高度}。 任何工具来MXML转换为?
你的addChild你RectangleShape?
