AS3 - 隐藏TileList的背景

Question

我正在使用带有自定义ImageCell类的tileList，我想隐藏M15＆amp ;;背后的灰色背景。 M19按钮。我试过设置background.alpha＆amp; ImageCell类上的opaqueBackground＆amp;没有运气的TileList ......

任何帮助都将不胜感激。

edit2：为清晰起见，添加tilelist设置和整个自定义单元格渲染器......

//TileList Settings in main class
tilelist.width = 235.53;
tilelist.height = 592;
tilelist.move(14, 118);
tilelist.columnWidth = 220.53;
tilelist.rowHeight = 53;
tilelist.visible = true;
tilelist.direction = ScrollBarDirection.VERTICAL;

tilelist.setStyle("cellRenderer", UserListRenderer);
tilelist.setStyle("contentBackgroundAlpha", 0);

//Custom CellRenderer
package {

    import fl.controls.listClasses.ICellRenderer;
    import fl.controls.listClasses.ImageCell;
    import fl.controls.TileList;
    import flash.text.*;

    public class UserListRenderer extends ImageCell implements ICellRenderer {

        public function UserListRenderer() {

            //inherit the variables from the parent
            super();

            //we don't want to stretch our images to fit the size of the box
            loader.scaleContent = true;

            //change the cursor as if this was a button
            useHandCursor = true;
        }

        override public function set data(data:Object):void
        {
            super.data = data;

            // Set the default skin to be invisible. This is a bit
            // easier than creating a new skin, if your goal is
            // to hide the white background.

            this.setStyle("contentBackgroundAlpha", 0);
        }

        /**
        * Now we override the function that draws the layout
        * so we can move the image beside the text
        **/
        override protected function drawLayout():void 
        {
            //adjust the icon for any existing padding
            var imagePadding:Number = getStyleValue("imagePadding") as Number;

            //offset the image in the box so it's not touching the top of it
            loader.move(1, 0);

            var h:Number = height-(imagePadding*2);*/

            var w:Number = width + (imagePadding*2);
            var h:Number = height + (imagePadding*2);

            if (loader.width != w && loader.height != h) {
                loader.setSize(w,h);
            }

            //re-draw the image
            loader.drawNow();

            //hide the original cellImage textField so we can display our new one later
            textField.visible = false;

            //adjust the background
            background.width = width;
            background.height = height;
        }
    }
}

For Flex：

list.setStyle("contentBackgroundAlpha", 0)

或者如果应用程序性能至关重要，请构建自定义皮肤

对于Flash Pro：

双击舞台上的列表以更改当前外观，或创建新外观并使用

进行分配

list.setStyle("skin", SkinName) //SkinName is a MovieClip in the library
