  * A <code>TextField</code> object is a text component
  * that allows for the editing of a single line of text.

+ * it will be replaced by a space character.

  * For example, the following image depicts a frame with four
  * text fields of varying widths. Two of these text fields
  * display the predefined text <code>"Hello"</code>.
