Testing whether objects and fields are enabled

Your application enables and disables objects, and the fields and widgets they contain, during the course of an application session. The ObjectEnabled and FieldsEnabled properties let you query the current state of the objects, fields, and widgets.

ObjectEnabled

This LOGICAL property, available for all visual SmartObjects, returns TRUE if the object itself has been enabled, and FALSE if it has not.

Normally, the framework enables every SmartObject as the application window initializes, unless the DisableOnInit property has been set to TRUE. Compare this property with the similar FieldsEnabled property for viewers and browsers. When the framework initializes a browser or viewer, its ObjectEnabled property is set to TRUE. If it has no enabled columns or fields, however, or if it is in View mode rather than Modify mode, then its FieldsEnabled property is FALSE. Thus the FieldsEnabled property alternates back and forth between TRUE and FALSE depending on the state of the window and the toolbar buttons, while the ObjectEnabled property is normally set to TRUE once and left that way.

FieldsEnabled

This LOGICAL property is TRUE when the fields or columns of a viewer or browser are enabled for data entry, and FALSE otherwise.
