How to modify a screen field using super class

[former_member1232704]

Hey gurus, I need a little help with objects. I'm starting with this and I'm a bit confused using the super class.

Let's say I have a screen field called 'campo' that based on a condition it must be disabled for input.

METHOD modificar.
  super->modificar( if_dynnr = if_dynnr)
<---code for the field 'campo' here--->
........

ENDMETHOD

What can I do to achieve this?

I don't understand your question. To have a field "Disabled for input", you use:

DATA ls_screen_element TYPE screen.
LOOP AT SCREEN INTO ls_screen_element.
  IF ls_screen_element-name = 'YOURFIELDNAME'.
    ls_screen_element-INPUT = '0'.
    MODIFY screen FROM ls_screen_element.
  ENDIF.
ENDLOOP.

I don't get what difficulty you have with ABAP Objects.

You can import SCREEN from your PBO into a method.

sandra.rossi

thankyou for your answer.

It seems that my problem is when can I use "normal" abap code when programming with ABAP Objects, like the code you wrote, 'MODIFY SCREEN FROM'.

Sorry for my English, guess is not good enough to explain myself.

[Sandra_Rossi]

"MODIFY screen FROM ... " is not an ABAP Objects construct. It's the recommended form. "MODIFY screen" without additional words is obsolete.

About English, I guess Google translator works well, so that should not be a problem to explain your issue.
