我使用的是 mxml 类,但由于我需要在构造时传递一些属性,为了更容易,我会将其转换为 as3 代码。
该类是 RectangleShape,它只绘制一个矩形。
原始mxml工作
<?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:fills>
<degrafa:SolidFill id="solidFill" color="white" alpha="0.3"/>
</degrafa:fills>
<degrafa:strokes>
<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>
我对 AS3 的尝试
包 org.edorado.edoboard.view.components.shapes { 进口 com.degrafa.geometry.RegularRectangle; 导入 com.degrafa.paint.SolidFill;进口 com.degrafa.paint.SolidStroke;导入 com.degrafa.GeometryGroup;导入 com.degrafa.Surface;导入 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;
}
}
}
问题是形状不再绘制,BaseShape 容器在那里,我可以看到跟踪拖动工作,但不再是矩形。
我错过了什么明显的东西吗?谢谢
