Field and Menu Information
The FieldObject class and its subclasses describe the fields and menu items on the form. Every field and menu item on your frame is associated with a reference variable that points to a FieldObject (for more information about referencing field and menu objects, see Field Function).
An object of the FieldObject class contains information about the appearance of the field and has methods for manipulating the field. For example, every button is associated with a ButtonField object that contains information about the button, such as its size, color, and title.
