Question

好的 - 希望这是关于flash的最后一篇文章：

我正在尝试在滚动窗格中突出显示文本。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，文本会突然显示一小段时间，然后才恢复正常。

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

我正在努力保持简短，但这是如何运作的：

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

修改

我记得有些组件可能会有一些延迟的启动例程。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 } } }
