Question

我有一个swfloader对象，我想放大（相对于一个点）....这是我在互联网上获得的一些帮助。

但现在我注意到，当我放大一点时，swf加载器上的滚动条不再起作用了....

我在下面使用的代码......关于如何纠正这个问题的任何想法???

<s:Scroller id="scrollme" width="100%" height="100%" >
    <s:HGroup id="mapView" width="100%" height="100%" clipAndEnableScrolling="true" >

        <s:SWFLoader id="img" autoLoad="true"  addedToStage="img_addedToStageHandler(event)" click="img_clicked(event)" maintainAspectRatio="true" includeIn="normal" />   
    </s:HGroup>
</s:Scroller>

和actionscript位

protected function onZoom(event:TransformGestureEvent):void
        {
            event.stopImmediatePropagation();
            scaleAt(event.scaleX,event.localX,event.localY)
        }
        public function scaleAt( scale : Number, originX : Number, originY : Number ) : void
        {
            // get the transformation matrix of this object
            affineTransform = img.content.transform.matrix; 
                //transform.matrix
            trace("zooming to " + scale)

            // move the object to (0/0) relative to the origin
            affineTransform.translate( -originX, -originY )

            // scale
            affineTransform.scale( scale, scale )

            // move the object back to its original position
            affineTransform.translate( originX, originY )


            // apply the new transformation to the object
            img.content.transform.matrix = affineTransform;
            //checkscroller();

        }
protected function img_addedToStageHandler(event:Event):void
        {
            Multitouch.inputMode = MultitouchInputMode.GESTURE;

            if (!Multitouch.supportsGestureEvents)
                currentState = "normal";
            else 
            {
                currentState = "normal";
                for each (var item:String in Multitouch.supportedGestures)
                {
                    if (item == TransformGestureEvent.GESTURE_PAN)
                        img.addEventListener(TransformGestureEvent.GESTURE_PAN, onPan);
                        /* else if (item == TransformGestureEvent.GESTURE_ROTATE)
                        img.addEventListener(TransformGestureEvent.GESTURE_ROTATE, onRotate); */
                    else if (item == TransformGestureEvent.GESTURE_SWIPE)
                        img.addEventListener(TransformGestureEvent.GESTURE_SWIPE, onSwipe);
                    else if (item == TransformGestureEvent.GESTURE_ZOOM)
                        img.addEventListener(TransformGestureEvent.GESTURE_ZOOM, onZoom);
                }
            }
        }

Answer 1

不确定我明白你在做什么。您正在使用SWFLoader加载图片？为什么不确定图像组件是否包含图像的URL源。

无论哪种方式，您都不能让HGroup包装您的组件并将clipAndEnableScrolling设置为true。删除该属性，你应该是好的。

<s:Scroller id="scrollme" width="100%" height="100%" >
    <s:HGroup id="mapView">
        <s:SWFLoader id="img" autoLoad="true"  addedToStage="img_addedToStageHandler(event)" click="img_clicked(event)" maintainAspectRatio="true" includeIn="normal" />   
    </s:HGroup>
</s:Scroller>

swfloader上的Flex Scroller在缩放时死亡
