在分配文本之前如何设置动态 UITextField 的正确宽度？
在 Flex 3.2 中，我创建一个 UITextField，然后测量要分配给该字段的文本属性的文本。 然后，我使用这些指标来设置字段的大小。 但是，计算出的宽度不足以容纳文本。 是否有不同的顺序来实现正确的测量，或者我发现measureText()函数有问题吗？ 我怎样才能得到准确的结果？
// UITextField's default size appears to be 100x100
// Measure the text then set width and height
var tf:UITextFormat = uiTextField.getUITextFormat();
var tlm:TextLineMetrics = tf.measureText(this.labelText);
// Text within the field is clipped unless 'padding' is added to the size
// Flex Documentation specifies there is a 2 px gutter on each side, so
// the expected padding would be 4 px. However, clipping occurs, for
// "Hello, World" up to 9 px.
uiTextField.width = tlm.width + 9;
uiTextField.height = tlm.height + 4;
uiTextField.border = true;
uiTextField.name = "uiTextField";
uiTextField.text = this.labelText;
In Flex 3.2, I'm creating a UITextField, then measuring text that I'm about to assign to that field's text property. I then use those metrics to set the size of the field. However, the calculated width is not wide enough to accommodate the text. Is there a different order to achieve proper measurement or am I seeing a problem with the measureText() function? How can I get accurate results?
// UITextField's default size appears to be 100x100
// Measure the text then set width and height
var tf:UITextFormat = uiTextField.getUITextFormat();
var tlm:TextLineMetrics = tf.measureText(this.labelText);
// Text within the field is clipped unless 'padding' is added to the size
// Flex Documentation specifies there is a 2 px gutter on each side, so
// the expected padding would be 4 px. However, clipping occurs, for
// "Hello, World" up to 9 px.
uiTextField.width = tlm.width + 9;
uiTextField.height = tlm.height + 4;
uiTextField.border = true;
uiTextField.name = "uiTextField";
uiTextField.text = this.labelText;

我之前在测量文本字段的宽度和高度时遇到过各种各样的麻烦。 看起来您只想自动调整文本字段的大小。 你有没有尝试过：
？？？
I've had all sorts of trouble with measuring the width and heights of textFields before. It looks like you just want to autosize the textField. Have you tried:

不幸的是，当 Flex 尝试动态获取 textWidth 时，它常常会感到非常困惑。 更糟糕的是，很难可靠地捕获错误并让 Flex 正确更新自身。 我发现的最好的选择：
mx.controls.Text hack AS3 描述了一种执行此操作的方法。
Unfortunately, Flex often gets very confused when it tries to dynamically get a textWidth. Even worse, it is difficult to reliably catch the error and have Flex update itself correctly. The best options I've found:
mx.controls.Text hack AS3 describes a way to do this.
