Check delete question

Question

Dear all,
Is there any trigger (or methods) in Forms that we can check immediately when the value of the field was changed without go to another field?
(Change value means clear the value by using back-space or delete button on the keyboard or when user type every word in the field.)
I am using Forms 10g.
Thanks for advance.
Regards.

Answer 1

not in forms-standard.
in forms 10g you could write a javabean overwriting the standard VTextField-class and check key-presses.
What is your actual requirement?
Addition:
There is a "very dirty" way to implement it with standard-forms-functionality, but i wouldn't recommend using it:
create a WHEN-NEW-ITEM-INSTANCE-trigger at form-level, in it save the items value to some control-item.
create a timer with some short time and in WHEN-TIMER-EXPIRED check if the actual field-value is different from the one saved in the WHEN-NEW-ITEM-INSTANCE-trigger
This solution has some disadvantages:
the timer forces a network trip,
if the time is choosen to short, then the form will do nothing but tripping over the network,
if the time is chosen to long, you will not get the userchange early enough for whatever you want to do.
as said before, i would not recommend doing it this way.
