Flex:[案例] Flash Builder 4中扩展TextLayout完美支持嵌入表情

使用textLayout跟aswing实现图文混排遇到的问题。

在mx组件的时候就将一个sprite通过这样：canvas.rawChildren.addChild(sprite);就可以将图片文字一起显示，而我用aswing组件实现的时候是这样写的：var sprite= new Sprite();var panel = new JPanel();panel.addChild(sprite);//这里我不清楚是否应该这么写，所以不确定怎么样才能让它显示出来。请教各位大侠textFlow = TextFilter.importToFlow(textInput,TextFilter.TEXT_LAYOUT_FORMAT); containerController = new DisplayObjectContainerController(textContainer,topPane.getPreferredWidth(),topPane.getPreferredHeight());textFlow.flowComposer.addController(containerController);textFlow.addEventListener(StatusChangeEvent.INLINE_GRAPHIC_STATUS_CHANGED,picLoaded);textFlow.interactionManager = new EditManager(new UndoManager());textFlow.interactionManager.setSelection(0,0);textFlow.flowComposer.updateAllContainers();

找到一个官方对TextFlow动态创建的说明

http://docs.huihoo.com/flex/4/flashx/textLayout/conversion/TextConverter.html

结合例子：

新浪微博AIR的图文混排表情出来啦。只是使用<img source=url 装入的图像不能播放gif，即只显示第一帧，不知道bmp图片能不能显示，有些flash的做法是将gif load进来后在play，将表情作为独立的覆盖层。

var markup:String = "<TextFlow xmlns='http://ns.adobe.com/textLayout/2008'><p><span>Hello,World</span></p></TextFlow>";var tFilter:TextConverter = new TextConverter();var textFlow:TextFlow = tFilter.importToFlow(markup,TextConverter.TEXT_LAYOUT_FORMAT);var exporter:ITextImporter = tFilter.getExporter(TextConverter.TEXT_LAYOUT_FORMAT));var export1:String = exporter.export();var export2:String = exporter.export();
