如何在textFlow中动态添加文本和标签

标签: flash flex actionscript

<s:RichEditableText editable="false" styleName="chatWin" height="550" width="100%">
        <s:textFlow>
            <s:TextFlow>
                    <s:p>Inline<s:br />TextFlow</s:p>
            </s:TextFlow>
        </s:textFlow>
</s:RichEditableText>

我想动态添加此<s:p>标记,从而进行聊天...我试过这个:

var p:p = new p();

但这不起作用

您可以通过附加到字符串变量并使用TextConverter.importToFlow()进行回流来编程方式更新文本,而不是MXML中的声明性文本流。

示例:

  

chat-window

在输入时,附加并重排输入字段中的文本:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx"
               minWidth="955"
               minHeight="600">

    <fx:Script>
        <![CDATA[
            import flashx.textLayout.conversion.TextConverter;
            import flashx.textLayout.elements.TextFlow;

            import mx.events.FlexEvent;

            [Bindable]
            public var text:String = "<p>Inline<br />TextFlow</p>";

            protected function input_enterHandler(event:FlexEvent):void
            {
                text += input.text;
                input.text = null;
            }
        ]]>
    </fx:Script>

    <s:layout>
        <s:VerticalLayout />
    </s:layout>

    <s:TextInput id="input"
                 enter="input_enterHandler(event)" />

    <s:RichEditableText editable="false"
                        selectable="true"
                        textFlow="{TextConverter.importToFlow(text, TextConverter.TEXT_FIELD_HTML_FORMAT)}"
                        buttonMode="true"
                        width="100%"
                        height="100%" />

</s:Application>
