GUI callback problem.

Hello Sir,

From the GUI code example below,
How can I make a callback statement
for the procedure " oferExampleFormCB(form) " in the main form?,
because I've got no output from the procedure "oferExampleFormCB(form) "
when I click the apply or ok button from the GUI.

Thanks in advance,
Marbs

Example code to demonstrate how to use various form functions,
use of loading and saving templates, dynamic field addition, etc.


Note that the templates don't include the values of the
dynamic fields - that's an exercise for the reader!
