Добрый день !

Подскажите плиз как словить event, когда пользователь кликает только одни раз по строке грида, double click не подходит! использую REUSE_ALV_GRID_DISPLAY_LVC.

Задача стоит так: есть колонка в виде сheck-box и колонка traffic-light, вот если пользователь изменил сheck-box - поставил галочку или убрал, соответственно traffic-light тоже изменяется.

Заранее спасибо! Smile

В этой теме REUSE & F4 разбиралась регистрация события по F4. Я думаю, что если заменить на событие DATA_CHANGED, то можно попробовать в нем одиночный клик эммулировать.

Code:
TYPE-POOLS: slis.

Как оказалось можно еще проще.
Code:
TYPE-POOLS: slis.

DATA: itab TYPE TABLE OF spfli,
      events TYPE slis_t_event,
      event TYPE slis_alv_event.
DATA: fcat TYPE lvc_t_fcat,
      hcat TYPE lvc_s_fcat,
      glay TYPE lvc_s_glay.

START-OF-SELECTION.
  SELECT * FROM spfli INTO TABLE itab.

END-OF-SELECTION.
  event-name = 'DATA_CHANGED'.
  event-form = 'DATA_CHANGED'.
  APPEND event TO events.

  CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name = 'SPFLI'
    CHANGING
      ct_fieldcat      = fcat.
  LOOP AT fcat INTO hcat
    WHERE fieldname = 'FLTYPE'.
    hcat-edit = 'X'.
    hcat-checkbox = 'X'.
    MODIFY fcat FROM hcat.
  ENDLOOP.

  glay-edt_cll_cb = 'X'.

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING
      i_callback_program = sy-cprog
      it_fieldcat_lvc    = fcat
      it_events          = events
      i_grid_settings    = glay
    TABLES
      t_outtab           = itab.

*&---------------------------------------------------------------------*
*&      Form  data_changed
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
FORM data_changed USING changed.
  BREAK-POINT.
ENDFORM.                    "data_changed
