Navigational triggers fire in response to navigational events.
Navigational triggers can be further sub-divided into two categories:
Pre- and Post- triggers, and When-New-Instance triggers. Pre- and Post-
Triggers fire as Oracle Forms navigates internally through different
levels of the object hierarchy. When-New-Instance-Triggers fire at the
end of a navigational sequence that places the input focus on a
different item i.e Instance Triggers fires before cursor present in the
particular object here objects are FORM, BLOCK, RECORD, ITEM.
Pre-Form:- Perform an action just before Oracle Forms navigates to the form from “outside” the form, such as at form startup.
Pre-Block:- Perform an action before Oracle Forms navigates to the block level from the form level.
