public class TextField extends TextInputControl
Text input component that allows a user to enter a single line of unformatted text. Unlike in previous releases of JavaFX, support for multi-line input is not available as part of the TextField control, however this is the sole-purpose of the `TextArea` control. Additionally, if you want a form of rich-text editing, there is also the `HTMLEditor` control.

TextField supports the notion of showing `prompt text` to the user when there is no `text` already in the TextField (either via the user, or set programmatically). This is a useful way of informing the user as to what is expected in the text field, without having to resort to `tooltips` or on-screen `labels`.

Example:

     var textField = new TextField("Hello World!");

Since:
  JavaFX 2.0

  - `TextArea`
