Release 10.1A: OpenEdge Development:
ADM Reference

ObjectHidden

Flag indicating whether or not the current object is hidden. Before checking ObjectHidden, the routine examines the parent state in ContainerHidden. If ContainerHidden is TRUE, there is no need to examine ObjectHidden, and the function immediately returns TRUE. Note that hidden is a logical concept in the ADM. A nonvisual object can be hidden to indicate that it is not currently active in some way, because it is a Container-Target of some visual object that is hidden.

Data type: LOGICAL
