Step 3: Declare visual classes and global functions – PB Docs 2018

Step 3:
Declare visual classes and global functions

You declare native visual classes in the same way as nonvisual
classes, except that you declare an ANSI C++ class that inherits from
IPBX_VisualObject, which is the ancestor class for all nonvisual
PowerBuilder native classes, instead of from IPBX_NonVisualObject. You
can also declare global functions in a visual extension. See Step 3: Declare native classes and
global functions in the section on nonvisual extensions.
