This example creates a single-line text field that's just big enough to display a text string using
the specified formatting.
var my_str:String = "Small string";
// Create a TextFormat object,
// and apply its properties.
var my_fmt:TextFormat = new TextFormat();
with (my_fmt) {
font = "Arial";
bold = true;
}
// Obtain metrics information for the text string
// with the specified formatting.
var metrics:Object = my_fmt.getTextExtent(my_str);
// Create a text field just large enough to display the text.
this.createTextField("my_txt", this.getNextHighestDepth(), 100, 100,
metrics.textFieldWidth,
metrics.textFieldHeight);
my_txt.border = true;
my_txt.wordWrap = true;
// Assign the same text string and TextFormat object to the my_txt object.
my_txt.text = my_str;
my_txt.setTextFormat(my_fmt);
The following example creates a multiline, 100-pixel-wide text field that's high enough to
display a string with the specified formatting.

var my_fmt:TextFormat = new TextFormat();
// Specify formatting properties for the TextFormat object:
my_fmt.font = "Arial";
my_fmt.bold = true;
my_fmt.leading = 4;
// The string of text to be displayed
var textToDisplay:String = "Macromedia Flash Player 7, now with improved
text metrics.";
// Obtain text measurement information for the string,
// wrapped at 100 pixels.
var metrics:Object = my_fmt.getTextExtent(textToDisplay, 100);
// Create a new TextField object using the metric
// information just obtained.
this.createTextField("my_txt", this.getNextHighestDepth(), 50, 50-
metrics.ascent, 100,
metrics.textFieldHeight);
