如何在使用自定義字體時將TLFTextField中的文本居中？

Question

按照標題，我該怎麼辦？下面是一個最小的工作例子反映了我的情況：

import fl.text.TLFTextField; 
import flashx.textLayout.formats.*; 
import flashx.textLayout.elements.TextFlow; 
import flashx.textLayout.edit.*; 

var tf:TLFTextField = new TLFTextField(); 
tf.embedFonts = true; 
tf.text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean suscipit semper viverra.'; 
var format:TextLayoutFormat = new TextLayoutFormat(); 
format.fontFamily = 'MyPlainFont'; 
format.fontLookup = FontLookup.EMBEDDED_CFF;  
format.fontSize = 14; 
format.textAlign = TextAlign.CENTER; 

var editManager:EditManager = new EditManager(); 
var sel:SelectionState = new SelectionState(tf.textFlow, 0, 86); 
tf.textFlow.interactionManager = editManager; 
editManager.applyLeafFormat(format, sel); 

var format2:TextLayoutFormat = new TextLayoutFormat(); 
format2.fontFamily = 'MyBoldFont'; 
format2.fontLookup = FontLookup.EMBEDDED_CFF; 
format2.fontSize = 14; 
format2.textAlign = TextAlign.CENTER; 
var sel2:SelectionState = new SelectionState(tf.textFlow, 0, 20); 
editManager.applyLeafFormat(format2, sel2); 

tf.width = 100; 
tf.wordWrap = true; 

addChild(tf);

對你有添加文本，否則它不適用前ASIGN格式正常的TextField，已嘗試？

以下代碼將解決您的問題。這就像Sidrich說的，總是設置文本屬性！我還添加了autoSize屬性，如果不設置此屬性，我會看到一些奇怪的定位故障。

import fl.text.TLFTextField; 
import flashx.textLayout.formats.TextLayoutFormat; 
import flashx.textLayout.edit.EditManager; 
import flashx.textLayout.formats.TextAlign; 
import flashx.textLayout.edit.SelectionState; 
import flash.text.TextFieldAutoSize; 

var tf:TLFTextField = new TLFTextField(); 
tf.embedFonts = true; 
tf.border = true; 

var format:TextLayoutFormat = new TextLayoutFormat(); 
format.fontFamily = 'MyPlainFont'; 
format.fontLookup = FontLookup.EMBEDDED_CFF;  
format.fontSize = 14; 
format.textAlign = TextAlign.CENTER; 
var editManager:EditManager = new EditManager(); 
var sel:SelectionState = new SelectionState(tf.textFlow, 0, 86); 
tf.textFlow.interactionManager = editManager; 
editManager.applyLeafFormat(format, sel); 

var format2:TextLayoutFormat = new TextLayoutFormat(); 
format2.fontFamily = 'MyBoldFont'; 
format2.fontLookup = FontLookup.EMBEDDED_CFF; 
format2.fontSize = 14; 
format2.textAlign = TextAlign.CENTER; 
var sel2:SelectionState = new SelectionState(tf.textFlow, 0, 20); 
editManager.applyLeafFormat(format2, sel2); 

tf.width = 100; 
tf.wordWrap = true; 
tf.autoSize = TextFieldAutoSize.CENTER; 
tf.text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean suscipit semper viverra.'; 

addChild(tf);

我有同樣的問題，我已經實現 http://flashthusiast.com/2010/05/05/getting-started-with-the-tlftextfield-class-in-actionscript-3-0-and-flash-cs5/comment-page-1/#comment-72699

，只是添加textAlign='center'段落標記在中心找到。

它屬於文本格式TLF flashx文本格式
