文本仅突出显示几分之一秒

Question

好的 - 这希望是我关于 Flash 的最后一篇文章：

我正在尝试突出显示滚动窗格中的文本。 现在我尝试在没有滚动窗格的情况下突出显示它，但问题是相同的，文本会突出显示几分之一秒，然后又恢复正常。

我正在使用 greensock LoaderMax 库将外部 swf 加载到滚动窗格中。

我试图让事情变得简短，但它是如何工作的：

也许您应该在设置颜色之前gotoAndStopMovieClip，否则第一个关键帧可能会重置文本。另外，尝试使用gotoAndStop(1);。 MovieClip 上不存在 0 帧。

我记得某些组件可能有稍微延迟的启动例程。试试这个：

function checkHandler(event:LoaderEvent):void {
    try {
        libMC = LoaderMax.getContent("childClip").rawContent as MovieClip;
        scrollPane.source = libMC;
        libMC.gotoAndStop(1); 
        setTimeout ( function ( libMC:MovieClip ) : void {
                         libMC.textSnapshot.setSelectColor( 0xFF0000 );
                         libMC.textSnapshot.setSelected( 100, 200, true ); 
                         }, 
                     100, 
                     libMC
                   );
        } catch (error:Error) {
            // statements
            ExternalInterface.call("window.alert(\"error: "+error.message+"\")");
        } finally {
            // statements
        }
    }
}
