Htmltext attributes of the flex4 and textarea controls

It now contains the text Layout Framework (Text Layout Framework (TLF), and TLF can be used

Spark text components, such as richtext, richeditabletext, textarea, and textinput.

Other components of the component, such as ComboBox and ComboBox, can contain a textinput control. Now you can refine the text and text streams

And can use your UI to implement a number of truly amazing applications. This framework is very extensive ....

Dizzy, it is estimated that you have read this article here and it is the same as me, It is endless confusion and helplessness, what should I do? Fortunately, after I studied it, I finally got it.

Let's talk about it as follows: The textarea control has a textflow attribute, which is like this. The following code is used:

<S: textarea id = "TXT" x = "185" Y = "122" textflow = "{textconverter. importtoflow (STR, textconverter. text_field_html_format)}">
</S: textarea>

If you write it in <FX: SCRIPT>, write it like this:

TXT. textflow = textconverter. importtoflow (STR, textconverter. text_field_html_format)

Here, txt is the Instance name of the textarea control, and STR is a character about htmltext;

Now let's give a complete generation:

 

<? 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" creationcomplete = "Init ()">
<S: textarea id = "TXT" x = "157" Y = "118"/>
<S: button id = "N" x = "360" Y = "334" label = "send"/>
<S: textinput id = "input" x = "167" Y = "332"/>
<FX: SCRIPT>
<! [CDATA [
