Using the METHOD textnote_editor->limit_text

[Former Member]

Hi guys,

I'm trying to use the method "textnote_editor->limit_text" to limit the rows in the text box, but there is an error message that this method is "Protected or Private". How can I use it or limit the rows in my text box ?

Best Regards.

Hi Carlos,

if you are talking about SAP standard class CL_GUI_TEXTEDIT, then you could create a new class INHERITED FROM CL_GUI_TEXTEDIT. Then you can use the protected method LIMIT_TEXT inside any new method.

CLASS LCL_TEXTEDIT DEFINITION INHERITING FROM CL_GUI_TEXTEDIT.
PUBLIC SECTION.
  methods MY_LIMIT_TEXT
    importing
      MAX_NUMBER_CHARS type I
    exceptions
      ERROR_CNTL_CALL_METHOD .

ENDCLASS.
CLASS LCL_TEXTEDIT IMPLEMENTATION.
  method my_limit_text.
    limit_text( MAX_NUMBER_CHARS ).
  endmethod.
ENDCLASS.

Now you have a public method. But as you do not describe your questions details, i have doubts that this solution works for you.

Hi Clemens how are you,

thanks for your help,

well, my problem continues, I declareted the public section like you sent-me and the error is the same, the error message is the Method LIMET_TEXT is private.

"Access to protected method "LIMIT_TEXT" is not allowed."

My problem is, I made a copy of standard FM "TXW_TEXTNOTE_EDIT" and I'm changing some declarations to try to block the rows in the text box, the user should not save a long text in the process, only the resume, thats why I need to block the rows and I tried to change some methods but nothing.

What I can do to do it on this FM ?.

Best Regards.

Hi Carlos,

what ever you did.

I just copied my code to a test program - no syntax error. That means I can use method MY_LIMIT_TEXT.

BUT: TXW_TEXTNOTE_EDIT can not save a text.

You can count the characters in the table returned and issue an error message instead of saving if there are too many.

* before saving...
field-symbols:
 <TXW_NOTE> type TXW_NOTE.
data:
  lv_charcount type sy-tleng.
loop at lT_TXWNOTE assigning <TXW_NOTE>,
   lv_charcount  =  lv_charcount  + strlen( <TXW_NOTE>-LINE ).
endloop.
if  lv_charcount  > lv_maxchars.
... MESSAGE Ennn(ZXY) with ...
endif.

Something like that.

Regards,

Clemens
