Error message in cl_gui_column_tree

Former Member — Mon, 04 Feb 2008 14:19:07 GMT

Hi all,

I'm trying to create a program (module pool) that should display a column tree. Some nodes has a context menu. What I need is to output an error message if the user click on a context menu choice that is not yet implemented.

Here is the code I'm using:

CLASS lcl_application DEFINITION.

  PUBLIC SECTION.
    METHODS:
      handle_ctx_menu_req
        FOR EVENT node_context_menu_request
        OF cl_gui_column_tree
        IMPORTING node_key
                  menu,

      handle_ctx_menu_sel
        FOR EVENT node_context_menu_select
        OF cl_gui_column_tree
        IMPORTING node_key
                  fcode.

ENDCLASS.

CLASS lcl_application IMPLEMENTATION.

  METHOD handle_ctx_menu_req.
  ...
  ENDMETHOD.

  METHOD handle_ctx_menu_sel.
    CASE fcode.
      WHEN co_display.
      ...
      WHEN co_edit.
        MESSAGE e049.
      WHEN OTHERS.
    ENDCASE.
  ENDMETHOD.

ENDCLASS.

The problem is that this code stops the application and put the user to the initial menu while what I want is to stay on the tree screen.

Help me please!

Stefano

hi,

try to use an other message type, e.g. type 'I' :

MESSAGE 'Function not implemented' TYPE 'I'.

hope this helps, regards

Hi Olaf,

of course it helps but the result is not exactly the same. I'd like to produce a "real" error message.

Thanks,

Stefano

hi,

perhaps this helps:

MESSAGE node_key TYPE 'S' display like 'E'. " display in "command line"

MESSAGE node_key TYPE 'I' display like 'E'. " display in popup

moreover perhaps the F1 Doku for "message" helps ?

regards
