從MovieClip中刪除內容（圖形線）

我有一個圖像庫加載一個細節圖像，然後根據圖像尺寸在圖像的一側繪製一條線。點擊圖像返回到主圖像縮略圖列表，然後單擊一個拇指將另一圖像加載到詳細信息持有者中。一切正常，除了線條，而不是消失在細節圖像卸載，積累。有沒有辦法清除lineDrawing MovieClip中的內容而無需將其從舞臺上移除，以便我可以在其中繪製一條新線？我已經嘗試過MovieClip上的removeChild，但是線條完全消失，與在setupDetail函數頂部放置lineDrawing.clear（）一樣。這是我的（相關的）代碼到目前爲止，任何援助將不勝感激，我很難過！從MovieClip中刪除內容（圖形線）

var detailImage:Loader = new Loader(); 
var lineDrawing:MovieClip = new MovieClip(); 

setupDetail(); 

function setupDetail():void { 
    detail.visible = false; 
    detail.buttonMode = true; 
    detail.closeMessage.mouseEnabled = false; 

    detail.addChild(detailImage); 

    detailImage.contentLoaderInfo.addEventListener(Event.COMPLETE, fullyLoaded); 

    // make sure detail is above the gallery 
    addChild(detail); 

    detail.addEventListener(MouseEvent.CLICK, onCloseDetail, false, 0, true); 
} 

function fullyLoaded(evt:Event):void { 

    var imgHeight:int = evt.target.content.height; 
    var imgWidth:int = evt.target.content.width; 

    var hOffset:int = imgWidth + 5 + 27; 
    var vOffset:int = imgHeight + 5; 

    detail.addChild(lineDrawing); 

    if(imgWidth == 600) { 
     lineDrawing.graphics.lineStyle(3,0x9a9345); 
     lineDrawing.graphics.moveTo(28,vOffset); 
     lineDrawing.graphics.lineTo(626,vOffset); 
    } 
    else if(imgHeight == 600) { 
     lineDrawing.graphics.lineStyle(3,0x9a9345); 
     lineDrawing.graphics.moveTo(hOffset, 1); 
     lineDrawing.graphics.lineTo(hOffset, 599); 
    } 
} 

function onCloseDetail(evt:MouseEvent):void { 

    // only allow it to be closed if it is at least 90% opaque 
    if (detailImage.alpha>.9){ 
     detailImage.unload(); 
     TweenLite.to(detail,.5, {autoAlpha:0}); 
     detailImage.unload(); 
     detail.visible = false; 
    } 
}

哇哦，謝謝，這工作完全置於onCloseDetail功能。再次感謝！！！ – 2010-07-31 17:00:56
