Hi Tummala,

You can use class CL_GUI_TEXT_EDIT.

DATA :  go_editor TYPE REF TO cl_gui_textedit,

" Create text editor
CREATE OBJECT go_editor
  EXPORTING
    wordwrap_mode   = go_editor->wordwrap_at_fixed_position
    wordwrap_position      = 8000
    wordwrap_to_linebreak_mode = go_editor->true
    parent                 = go_container
  EXCEPTIONS
    OTHERS                 = 1.

" Put it in read-only mode
CALL METHOD go_editor->set_readonly_mode
  EXPORTING
    readonly_mode          = go_apercu_fichier->&1
  EXCEPTIONS
    OTHERS                 = 1.

Best regards,

Samuel

Hi Swapna, Steps to develop Text editor <li>Need to create screen <li>Place Custom container on the screen. <li>Bind the bind TextEdit Control with Custom container. <li>Check the demo programs

1.SAPTEXTEDIT_DEMO_1
2.SAPTEXTEDIT_DEMO_3
3.SAPTEXTEDIT_TEST_2

<li>Check the SAP help documentation. http://help.sap.com/saphelp_nw2004s/helpdata/en/f1/549e36cf0ecb7de10000009b38f889/frameset.htm Thanks Venkat.O

Hi,

Text editor is displayed on screen using custom control. So we need a container for the custom control. And text editor control is implemented using class CL_GUI_TEXTEDIT.

declaration part contains

DATA: LINE_LENGTH      TYPE I VALUE 254,
      EDITOR_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER,
      TEXT_EDITOR      TYPE REF TO CL_GUI_TEXTEDIT,
      TEXT             TYPE STRING.

Then call the screen (can be any number)

START-OF-SELECTION.
  CALL SCREEN '100'.

Go to screen 100 by double clicking on '100'.

Create a custom control on screen with name TEXTEDIT.

Uncomment both PBO and PAI modules in flow logic screen

PROCESS BEFORE OUTPUT.
 MODULE STATUS_0100.
*
PROCESS AFTER INPUT.
 MODULE USER_COMMAND_0100.

Define and implement both the modules in the main program itself.

In PBO create object container EDITOR_CONTAINER. Then create text editor object by exporting the container EDITOR_CONTAINER.

CREATE OBJECT EDITOR_CONTAINER
      EXPORTING
        CONTAINER_NAME              = 'TEXTEDITOR'
      EXCEPTIONS
        CNTL_ERROR                  = 1
        CNTL_SYSTEM_ERROR           = 2
        CREATE_ERROR                = 3
        LIFETIME_ERROR              = 4
        LIFETIME_DYNPRO_DYNPRO_LINK = 5.

    CREATE OBJECT TEXT_EDITOR
      EXPORTING
        PARENT           = EDITOR_CONTAINER
        WORDWRAP_MODE    = CL_GUI_TEXTEDIT=>WORDWRAP_AT_FIXED_POSITION
        WORDWRAP_POSITION          = LINE_LENGTH
        WORDWRAP_TO_LINEBREAK_MODE = CL_GUI_TEXTEDIT=>TRUE.

You can hide the toolbar and as well as status bar for the text editor control.

CALL METHOD TEXT_EDITOR->SET_TOOLBAR_MODE
      EXPORTING
        TOOLBAR_MODE = CL_GUI_TEXTEDIT=>FALSE.

    CALL METHOD TEXT_EDITOR->SET_STATUSBAR_MODE
      EXPORTING
        STATUSBAR_MODE = CL_GUI_TEXTEDIT=>FALSE.

Define and create a GUI Status in the PBO.

SET PF-STATUS 'STATUS_0100'.

In PAI of the screen 100, handle the save and other user commands.

CASE SY-UCOMM.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
    WHEN 'SAVE'.
      CALL METHOD TEXT_EDITOR->GET_TEXTSTREAM
*         EXPORTING
*             ONLY_WHEN_MODIFIED     = CL_GUI_TEXTEDIT=>TRUE
          IMPORTING
              TEXT                   = TEXT
*             IS_MODIFIED            =
          EXCEPTIONS
              ERROR_CNTL_CALL_METHOD = 1
              NOT_SUPPORTED_BY_GUI   = 2
              OTHERS                 = 3.

      IF SY-SUBRC <> 0.
        MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
                   WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.

      CALL METHOD CL_GUI_CFW=>FLUSH
        EXCEPTIONS
          CNTL_SYSTEM_ERROR = 1
          CNTL_ERROR        = 2
          OTHERS            = 3.
      MESSAGE TEXT TYPE 'I'.
  ENDCASE.

To read the text that is typed in the editor we need to call the method GET_TEXTSTREAM of the editor instance.

We are just displaying the text typed in the editor in an informative message; the same can be inserted / updated into a database table also.

The complete coding of the executable program is given below..

REPORT  ZTEXT_EDITOR.

DATA: LINE_LENGTH      TYPE I VALUE 254,
      EDITOR_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER,
      TEXT_EDITOR      TYPE REF TO CL_GUI_TEXTEDIT,
      TEXT             TYPE STRING.

START-OF-SELECTION.
  CALL SCREEN '100'.

**&---------------------------------------------------------------------*
**&      Module  STATUS_0100  OUTPUT
**&---------------------------------------------------------------------*
**       text
**----------------------------------------------------------------------*
MODULE STATUS_0100 OUTPUT.

  SET PF-STATUS 'STATUS_0100'.

  IF TEXT_EDITOR IS INITIAL.

    CREATE OBJECT EDITOR_CONTAINER
      EXPORTING
        CONTAINER_NAME              = 'TEXTEDITOR'
      EXCEPTIONS
        CNTL_ERROR                  = 1
        CNTL_SYSTEM_ERROR           = 2
        CREATE_ERROR                = 3
        LIFETIME_ERROR              = 4
        LIFETIME_DYNPRO_DYNPRO_LINK = 5.

    CREATE OBJECT TEXT_EDITOR
      EXPORTING
        PARENT                     = EDITOR_CONTAINER
        WORDWRAP_MODE              = CL_GUI_TEXTEDIT=>WORDWRAP_AT_FIXED_POSITION
        WORDWRAP_POSITION          = LINE_LENGTH
        WORDWRAP_TO_LINEBREAK_MODE = CL_GUI_TEXTEDIT=>TRUE.


*3)HIDE TOOLBAR AND STATUSBAR

    CALL METHOD TEXT_EDITOR->SET_TOOLBAR_MODE
      EXPORTING
        TOOLBAR_MODE = CL_GUI_TEXTEDIT=>FALSE.

    CALL METHOD TEXT_EDITOR->SET_STATUSBAR_MODE
      EXPORTING
        STATUSBAR_MODE = CL_GUI_TEXTEDIT=>FALSE.

  ENDIF.
ENDMODULE.                 " STATUS_0100  OUTPUT
*&---------------------------------------------------------------------*
*&      Module  USER_COMMAND_0100  INPUT
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
MODULE USER_COMMAND_0100 INPUT.
  CASE SY-UCOMM.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
    WHEN 'SAVE'.
      CALL METHOD TEXT_EDITOR->GET_TEXTSTREAM
*         EXPORTING
*             ONLY_WHEN_MODIFIED     = CL_GUI_TEXTEDIT=>TRUE
          IMPORTING
              TEXT                   = TEXT
*             IS_MODIFIED            =
          EXCEPTIONS
              ERROR_CNTL_CALL_METHOD = 1
              NOT_SUPPORTED_BY_GUI   = 2
              OTHERS                 = 3.

      IF SY-SUBRC <> 0.
        MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
                   WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.

      CALL METHOD CL_GUI_CFW=>FLUSH
        EXCEPTIONS
          CNTL_SYSTEM_ERROR = 1
          CNTL_ERROR        = 2
          OTHERS            = 3.
      MESSAGE TEXT TYPE 'I'.
  ENDCASE.
ENDMODULE.                 " USER_COMMAND_0100  INPUT
