Java only
FieldInterfacedefines the methods for objects representing fields. In addition, objects of typeFieldInterfacesupport all the methods inWidgetInterface.Java objects representing text fields, push buttons, toggle buttons, check boxes, radio buttons, dynamic labels, tab cards, option menus, combo boxes and scales are of type
FieldInterface.The method
getScreenwill return an object corresponding to the screen on which the field in question is found.The other methods correspond in functionality to Panther library functions that have the same name, only with an
sm_prefix. Those library functions take parameters to indicate which field the function should operate on. Since these are methods of objects that correspond to fields, the field in question is always implicitly indicated.
