我正在使用 Flash CS5 和 ActionScript 3。

我需要动态（响应事件）将 TLFTextField 的 wordWrap 属性从 true 翻转为 false，反之亦然。我让它与旧的 TextField 类一起使用，但我无法让它与 TLF 一起使用。

我声明我的字段并像这样设置它，将 wordWrap 设置为 true：

this.field = new TLFTextField;
field.multiline = true;
field.wordWrap = true;
field.autoSize = TextFieldAutoSize.LEFT;

field.tlfMarkup = my_content;

this.addChild(field);
var myTextFlow:TextFlow = field.textFlow;
myTextFlow.hostFormat = format; //format is a TextLayoutFormat declared earlier
myTextFlow.flowComposer.updateAllControllers();

要更改自动换行，我尝试了以下方法：

field.wordWrap = false;
field.multiline = false;
var myTextFlow:TextFlow = field.textFlow;
myTextFlow.flowComposer.updateAllControllers();

但这没有任何效果 - 文本保持换行。谁能告诉我我错过了什么？

提前致谢，

要将 wordwrap 更改为 false，必须设置文本。（我需要大约半小时才能让它工作！）

field.wordWrap = false;
trace(field.wordWrap); // will echo true

以下应该有效：

if(field.text == ""){

  field.text = "a";
  field.wordWrap = false;
  field.text = "";

} else {

  field.wordWrap = false;

}

trace(field.wordWrap); // should echo false

First off, have you tried: this.field = new TLFTextField();

You didn't have the parenthesis.

At least worth a look at. (Also I believe this is Beta currently so there is a possibility of a bug?)

Finally, you might consider testing this without the AutoSize... sometimes causes problems.

Sorry that I can't be a little more helpful with an exact solution.
