How to get keyboard cursor on specific field with a condition

Question

I am using forms6i. i have two fields 1st field1 and field2. I want that when field1='A' then keyboard cursor go to field2 else it must automatically skip the field2. and the condition is that the trigger must not be key-next-item, because if this process completed or not we have to go to next record and to save it.How is this possible???

Answer 1

Depending on how your users navigate your application (mostly keyboard or combination of keyboard and mouse) the Key-Next-Item (KNI) trigger will not file if the user uses the mouse to leave Field1. Rather than use the KNI trigger I suggest you use a combination of the When-Validate-Item (WVI) and the Module/Form level When-Timer-Expired (WTE) triggers. This ensures no matter how your user leaves Field1 that the navigation cursor will go to Field2 if the value of field1 is 'A'. For example:
/* Sample WVI trigger */
DECLARE
   timer_id   TIMER;
BEGIN
   IF ( :FIELD1 = 'A' ) THEN
      Create_Timer('GOTO_FIELDB',1,NO_REPEAT);
   END IF;
END;This code creates a 1 millisecond timer which will execute immediately so there is no lag in your application. Also, since it is a 1 millisecond timer, it will not cause a network trip to the application server.
/* Sample WTE trigger */
/* This is a Module/Form level trigger */
DECLARE
   v_Timer   VARCHAR2(30) := Get_Application_Property(TIMER_NAME);
BEGIN
   IF ( v_timer = 'GOTO_FIELDB' ) THEN
      Go_Item('FIELDB');
   END IF;
END;Hope this helps,
