Applying styles to a TextField object

To apply a style sheet object to a TextField object, you assign the style sheet object to the text field's styleSheet property.

textObj_txt.styleSheet = styles;

NOTE

Do not confuse the TextField.styleSheet property with the TextField.StyleSheet class. The capitalization indicates the difference.

When you assign a style sheet object to a TextField object, the following changes occur to the text field's normal behavior:

The text field's text and htmlText properties, and any variable associated with the text field, always contain the same value and behave identically.
The text field becomes read-only and cannot be edited by the user.
The setTextFormat() and replaceSel() methods of the TextField class no longer function with the text field. The only way to change the field is by altering the text field's text or htmlText property or by changing the text field's associated variable.
Any text assigned to the text field's text property, htmlText property, or associated variable is stored verbatim; anything written to one of these properties can be retrieved in the text's original form.
