Problem with CL_GUI_TEXTEDIT

Former Member — Fri, 14 Jul 2006 18:38:57 GMT

I use class CL_GUI_TEXTEDIT to enter and edit some text,but also i need to provide some extra functions, for examle, guving possibility to surround selected text with tags <b> and </b>. The simpliest way to provide this - adding button with this handler:


      CALL METHOD G_TEXTEDITOR->GET_SELECTED_TEXTSTREAM
        IMPORTING
          SELECTED_TEXT = SELECTED.

      CONCATENATE '<b>' SELECTED '</b>' INTO SELECTED.

      CALL METHOD G_TEXTEDITOR->SET_SELECTED_TEXTSTREAM
        EXPORTING
          SELECTED_TEXT                 = SELECTED
          ENABLE_EDITING_PROTECTED_TEXT = CL_GUI_TEXTEDIT=>TRUE.

The problem is, that the first part take the selected text, but SET_SELECTED_TEXT running without any exceptions, but do nothing, text in my textedit doesn't change.

(excuse the code,i enter it from my home from memory)

Does anybody have any ideas?

Please see the same program, create the MAIN gui status and put a button on the application toolbar, give fcode as "SWITCH". Then run the program, enter a few lines, select lines 2-4 and click switch button, you will see that the selected text is then wrapped with your tags.



report zrich_0001 .

data:
      dockingleft  type ref to cl_gui_docking_container,
      text_editor    type ref to cl_gui_textedit,
      repid type syrepid.

data: itext type table of tline-tdline,
      xtext type tline-tdline.

parameters: p_check.

initialization.

  repid = sy-repid.
  create object dockingleft
              exporting repid     = repid
                        dynnr     = sy-dynnr
                        side      = dockingleft->dock_at_left
                        extension = 1070.
  if text_editor is initial.
    create object text_editor
                exporting
                     parent     = dockingleft.

  endif.

  set pf-status 'MAIN'.

at selection-screen.


check  sy-ucomm = 'SWITCH'.

      call method text_editor->get_selected_text_as_r3table
                importing
                    table = itext
                exceptions
                    potential_data_loss = 1.

      xtext = '<b>'.   insert xtext into itext index 1.
      xtext = '</b>'.  append xtext to itext.


      call method text_editor->set_selected_text_as_r3table
              exporting table = itext.

Thanks a lot, it solve the problem in some way. But with tags <b> it surround text with '/n'.

Re: Problem with CL_GUI_TEXTEDIT

Former Member — Mon, 17 Jul 2006 07:19:20 GMT

The proper way is:


      DATA: ITEXT TYPE TABLE OF TLINE-TDLINE,
           XTEXT TYPE TLINE-TDLINE.

      CALL METHOD G_TEXTEDITOR->GET_SELECTED_TEXT_AS_R3TABLE
        IMPORTING
          TABLE               = ITEXT
        EXCEPTIONS
          POTENTIAL_DATA_LOSS = 1.

      READ TABLE ITEXT INTO XTEXT INDEX 1.
      CONCATENATE '<b>' XTEXT INTO XTEXT.
      MODIFY ITEXT FROM XTEXT INDEX 1.

      DESCRIBE TABLE ITEXT.

      READ TABLE ITEXT INTO XTEXT INDEX SY-TFILL.
      CONCATENATE XTEXT '</b>' INTO XTEXT.
      MODIFY ITEXT FROM XTEXT INDEX SY-TFILL.

      CALL METHOD G_TEXTEDITOR->SET_SELECTED_TEXT_AS_R3TABLE
        EXPORTING
          TABLE = ITEXT.
