You can attach Key-Fn triggers to 10 keys or key sequences that normally do not perform any Oracle Forms operations. These keys are referred to as Key-F0 through Key-F9. Before you can attach key triggers to these keys, you or the DBA must use Oracle Terminal to map the keys to the appropriate functions. A Key-Others trigger is associated with all keys that can have key triggers associated with them but are not currently defined by function key triggers at any level.

A Key-Others trigger overrides the default behavior of a Runform function key unless one of the restrictions apply. When this occurs, however, Oracle Forms still displays the function key's default entry in the Show Keys screen. It fires when there is an attempt to delete a record in the master block of a master-detail relation. A coordination-causing event is any event that makes a different record the current record in the master block. It fires when Oracle Forms would normally need to populate the detail block in a master-detail relation.

Specifically, the Post-Record trigger fires whenever the operator or the application moves the input focus from one record to another. Specifically, this trigger fires when the input focus moves from a text item to any other item. Specifically, it fires after navigation to an item, when Oracle Forms is ready to accept input in a block that is different than the block that previously had input focus. A When-New-Form-Instance trigger fires after the successful completion of any navigational triggers that fire during the initial navigation sequence.

This trigger does not fire when control returns to a calling form from a called form. In a multiple-form application, this trigger does not fire when focus changes from one form to another. Specifically, it fires after navigation to an item, when Oracle Forms is ready to accept input in an item that is different than the item that previously had input focus. Specifically, it fires after navigation to an item in a record, when Oracle Forms is ready to accept input in a record that is different than the record that previously had input focus.

Fires whenever Oracle Forms instantiates a new record. The trigger fires once for each record placed on the block's list of records. It fires once for each record that has been inserted or updated. By default, Oracle Forms closes a query when all of the records identified by the query criteria have been fetched, or when the operator or the application aborts the query.

The On-Close trigger augments the normal Oracle Forms "close cursor" phase of 1. By default, this operation occurs after all records that have been marked as updates, inserts, and deletes have been posted to the database. When the On-Count trigger completes execution, Oracle Forms issues the standard query hits message: Query will retrieve records. Specifically, it fires after the Pre-Delete trigger fires and before the Post-Delete trigger fires, replacing the actual database delete of a given row.

The trigger fires once for each row that is marked for deletion from the database. While the query remains open, fires again each time a set of rows must be fetched into the block.

Specifically, it fires after the Pre-Insert trigger fires and before the Post-Insert trigger fires, when Oracle Forms would normally insert a record in the database. It fires once for each row that is marked for insertion into the database. The trigger fires between the keypress and the display of the modified data. By default, Oracle Forms issues savepoints at form startup, and at the start of each Post and Commit Transaction process.

Specifically, it fires after the Pre-Update trigger fires and before the Post-Update trigger fires, when Oracle Forms would normally update a record in the database. It fires once for each row that is marked for update in the form.

In this case, the When-Validate-Item trigger does not fire. If you want to circumvent this situation and effectively get rid of the Post-Change trigger, you must include a Post-Query trigger in addition to your When-Validate-Item trigger. See "Usage Notes" below. Note that the Post-Forms-Commit trigger fires after inserts, updates, and deletes have been posted to the database, but before the transaction has been finalized by issuing the Commit.

It fires once for each row that is deleted from the database during the commit process. If there are records in the form that have been marked as inserts, updates, or deletes, the Post-Forms-Commit trigger fires after these changes have been written to the database but before Oracle Forms issues the database Commit to finalize the transaction.

If the operator or the application initiates a Commit when there are no records in the form have been marked as inserts, updates, or deletes, Oracle Forms fires the Post-Forms-Commit trigger immediately, without posting changes to the database. It fires once for each record that is inserted into the database during the commit process.
