Form and Gadget Callbacks
Note:
Form and Gadget Callbacks looks at the callback in more detail. If you are reading the PML Customisation User Guide for the first time then you may want to skip this section and return to it later.
Before you read this section you should have read and understood the Form Concepts section, in which you saw that callbacks are user-defined actions which are assigned to a form and its gadgets.
They are supplied as text strings and may be any valid PML expression, PML Function or method call, including any form, gadget or user-defined object method.
