Object Groups:
An object group is a container for a group of objects. You describe an object group when you need to package related objects so you can copy or reference them in another module.
Object groups give a way to bundle objects into higher level building blocks which can be used in other categories of an application and in following development projects.
For instance you may build an appointment scheduler in a form and then decide to make it available from other forms in your applications. The scheduler would possibly be establish from various types of objects, involving a canvas and window view, blocks, and items which display dates and appointments and triggers which holds the logic for scheduling and other functionality. If you packaged these objects into an object group then you could then copy them to any number of other forms in single simple operation.
You can create object groups in menu and form modules. Once you create an object group, you should remove and add objects to it as desired.
