Using class user objects – PB Docs 2017

To instantiate a class user object

1. In the window or user object in which you want to use the
   class user object, declare a variable of the user object type and
   create an instance of it using the CREATE statement. For
   example:

   PowerBuilder

   // declared instance variable: // n_myobject invo_myobject invo_myobject = CREATE n_myobject

   1 2 3

   // declared instance variable: // n_myobject invo_myobject invo_myobject = CREATE n_myobject

2. Use the user object’s properties and functions to do the
   required processing.

3. When you have finished using the user object, destroy it
   using the DESTROY statement.

   If you select Autoinstantiate in the properties of the class
   user object, you cannot use the CREATE and DESTROY
   statements.

To insert a class user object

1. Open the window or user object in which you want to insert
   the class user object.

2. Select Insert>Object from the menu bar.

3. Select User Object (at the bottom of the list) and then
   select the class user object you want to insert.

   PowerBuilder inserts the selected class user object.

4. Modify the properties and code the events of the nonvisual
   object as needed.

   When the user object is created in an application, the
   nonvisual object it contains is created automatically. When the
   user object is destroyed, the nonvisual object is destroyed
   automatically.
