	/**
	 * The student_ar_fl_controls_TextInput component is a single-line text component that
	 * contains a native ActionScript TextField object. 
	 *
	 * <p>A student_ar_fl_controls_TextInput component can be enabled or disabled in an application.
	 * When the student_ar_fl_controls_TextInput component is disabled, it cannot receive input 
	 * from mouse or keyboard. An enabled student_ar_fl_controls_TextInput component implements focus, 
	 * selection, and navigation like an ActionScript TextField object.</p>
	 *
	 * <p>You can use styles to customize the student_ar_fl_controls_TextInput component by
	 * changing its appearance--for example, when it is disabled.
	 * Some other customizations that you can apply to this component
	 * include formatting it with HTML or setting it to be a
	 * password field whose text must be hidden. </p>
