在ALV里编写回车事件

1.定义类

*---------------------------------------------------------------------*
* CLASS lcl_grid_event_receiver DEFINITION
*---------------------------------------------------------------------*
CLASS lcl_grid_event_receiver DEFINITION .
  PUBLIC SECTION.
    METHODS:
*    toolbar
*      FOR EVENT toolbar  OF cl_gui_alv_grid
*              IMPORTING e_object  e_interactive ,
    user_command
      FOR EVENT user_command  OF cl_gui_alv_grid
             IMPORTING e_ucomm   ,
     handle_data_changed
        FOR EVENT data_changed OF cl_gui_alv_grid
            IMPORTING er_data_changed.

  PRIVATE SECTION.
* This flag is set if any error occured in one of the
* following methods:
    DATA: error_in_data TYPE c.
    METHODS: check_bcje
                IMPORTING
                    ps_good_bcje TYPE lvc_s_modi
                    pr_data_changed TYPE REF TO cl_alv_changed_data_protocol.
ENDCLASS.                    "lcl_grid_event_receiver DEFINITION

DATA : grid_handler TYPE REF TO lcl_grid_event_receiver.

 

2.定义方法

*&---------------------------------------------------------------------*
*&       Class (Implementation)  lcl_grid_event_receiver
*&---------------------------------------------------------------------*
*        Text
*----------------------------------------------------------------------*
CLASS lcl_grid_event_receiver IMPLEMENTATION.
**----------------------------------------------------------------------
** Method to handle user commands from toolbar
**----------------------------------------------------------------------
  METHOD user_command.
    CASE e_ucomm .
      WHEN ''.

    ENDCASE.

  ENDMETHOD.                    "user_command

  METHOD handle_data_changed.
    DATA: ls_good TYPE lvc_s_modi.
    error_in_data = space.

    LOOP AT er_data_changed->mt_good_cells INTO ls_good.
      CASE ls_good-fieldname.
        WHEN 'BCJE'.
          CALL METHOD check_bcje
            EXPORTING
              ps_good_bcje    = ls_good
              pr_data_changed = er_data_changed.

      ENDCASE.
    ENDLOOP.
  ENDMETHOD.                    "handle_data_changed

  METHOD check_bcje.
    DATA bcje TYPE ekpo-netwr.
    CALL METHOD pr_data_changed->get_cell_value
      EXPORTING
        i_row_id    = ps_good_bcje-row_id
        i_fieldname = ps_good_bcje-fieldname
      IMPORTING
        e_value     = bcje.
        break-point.

        IF bcje IS NOT INITIAL.
      READ TABLE item into type_item1 INDEX ps_good_bcje-row_id.
*      ASSIGN item TO .
*      -bcje = bcje.
      type_item1-bcje = bcje.
      MODIFY item from type_item1 INDEX ps_good_bcje-row_id.
      CLEAR:item,type_item1.
      CALL METHOD alv_grid->refresh_table_display .
    ENDIF.

 

  ENDMETHOD.                    "check_planetype

ENDCLASS.               "lcl_grid_event_receiver

 

3.在build_objects里添加回车事件

  IF grid_handler IS INITIAL.
    CREATE OBJECT grid_handler.
    SET HANDLER:
    grid_handler->user_command FOR alv_grid,
    grid_handler->handle_data_changed FOR alv_grid."加回车事件

  ENDIF.

4.在初始化里加上一下语句

 

  CALL METHOD alv_grid->set_ready_for_input
    EXPORTING
      i_ready_for_input = 1.
  CALL METHOD alv_grid->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_modified.

 

现在可以发现你在单元格里输入某个数据后，按回车或者将鼠标放到其他地方，会自动检测你的输入内容并进行你所要的操作！
