Methods

System generated methods, also known as system methods, standard methods or
object methods, attached to the form are used to control the startup and shut
down of the form. These events are frequently overridden to make initialization
of the form. By default, the system methods are not displayed. To override a
system method, right
-click on the Methods node, select Override Method and
then select the methods to override.
Other methods can be added and called from anywhere in the form. It is good
practice to add methods here rather than writing large chunks of code in the
objects deeper in the form design, as it makes locating code simpler.
Variables defined in the class declaration of the individual form can be accessed
from all methods in the form and can be used to hold the status of the form
controls.
The following illustration shows the
CustTable form methods. The form system
methods task, run, init and close have been overridden. All other methods have
been added to the
Methods node and are specific to this form.
