Short Name: Owner

Requires: Base Development System

Class: Generic Properties

To Use: Create a property.

Reference to the owning object. The type of the reference is Generic. An object of class Panel does not have an owner (it is the top-level object) and always returns Not A Refnum.

All objects in LabVIEW have an owning object. For example, the front panel and block diagram are the owning objects of all the objects contained within each, including controls and indicators. However, if a control is a cluster, the cluster would the owning object of all the objects inside it. Likewise, if the block diagram contains a sequence structure, the structure is the owning object of all the objects inside it. Individual controls also can be the owning object of less obvious objects. For example, numeric controls own their label, caption, and the increment and decrement buttons.
