OO方式实现ALV: cl_salv_table

这里总结最近用cl_salv_table实现ALV遇到问题和解决办法

FORM set_alv2 .
DATA: lv_syrepid TYPE syrepid.
      lv_syrepid  = sy-cprog.
      cl_salv_table=>factory(
        EXPORTING
        list_display = abap_false
        r_container = cl_gui_container=>screen0
        IMPORTING
          r_salv_table = gr_alv
        CHANGING t_table = gt_doc ). “传输需要显示的内表

      gr_functions = gr_alv->get_functions( ).        "获取常用的ALV功能按钮


DATA lv_icon TYPE string.
lv_icon = icon_refresh.
gr_functions->add_function(       "添加自定义按钮
 EXPORTING
   name = 'DOWNLOAD'
   icon = '@M9@'
   text = '下载文档'
   tooltip = '下载文档'
   position = if_salv_c_function_position=>right_of_salv_functions ). "往右边排

gr_functions->add_function(
 EXPORTING
   name = 'SELECT_ALL'
   icon = '@4B@'
   text = '全选'
   tooltip = '全选'
   position = if_salv_c_function_position=>left_of_salv_functions ). "往右边排

gr_functions->add_function(
 EXPORTING
   name = 'DESELECT_ALL'
   icon = '@4D@'
   text = '取消全选'
   tooltip = '取消全选'
   position = if_salv_c_function_position=>left_of_salv_functions ). "往右边排

gr_functions->set_all( abap_true ). ”设置所有alv按钮(自带的+自定义的)
"=====获取事件对象
DATA: gr_event TYPE REF TO cl_salv_events_table.
gr_event = gr_alv->get_event( ).

"=====事件注册
DATA: gr_handle_event TYPE REF TO cl_handle_events.
CREATE OBJECT gr_handle_event.
SET HANDLER gr_handle_event->on_user_command FOR gr_event.
SET HANDLER gr_handle_event->on_checkbox     FOR gr_event.
DATA: gr_column_list TYPE REF TO cl_salv_column_list.

      gr_columns = gr_alv->get_columns( ).               "获取列的class
      gr_column  = gr_columns->get_column('ACTION_NO').  "获取该列 
      gr_column->set_short_text('需求号').        "调用修改列名称的方法
      gr_columns->set_optimize( abap_true ).      "调用设置列最优化设置方法这边用到列实例是gr_colums不是gr_colum

      gr_column = gr_columns->get_column('FLAG').  

      gr_column->set_short_text('选择').
      gr_columnt ?= gr_column.                      "这边很重要
      gr_columnt->set_cell_type( 6 ).          "设置选择列为checkbox,6代表checkbox

      gr_display = gr_alv->get_display_settings( ).  "alv设置
      gr_display->set_list_header('需求号&文档编号报表'). "alv抬头设置
      gr_alv->display( )."调用实例方法显示表报        "调用显示alv方法展示ALV报表
ENDFORM.                    " SET_ALV2
下面是是事件的class的定义
CLASS
cl_handle_events DEFINITION. PUBLIC SECTION. METHODS: on_user_command FOR EVENT added_function OF cl_salv_events_table IMPORTING e_salv_function, on_checkbox FOR EVENT link_click OF cl_salv_events_table IMPORTING row column. ENDCLASS. CLASS cl_handle_events IMPLEMENTATION. METHOD on_user_command. PERFORM handle_user_command USING e_salv_function. ENDMETHOD. METHOD on_checkbox. PERFORM handle_clickbox USING row column. ENDMETHOD. ENDCLASS.
事件的方法定义
FORM
handle_user_command USING p_function TYPE salv_de_function. CASE p_function. WHEN 'DOWNLOAD'. PERFORM down_doc. WHEN 'DESELECT_ALL'. gs_doc-flag = ' '. MODIFY gt_doc FROM gs_doc TRANSPORTING flag WHERE flag = 'X'. WHEN 'SELECT_ALL'. gs_doc-flag = 'X'. MODIFY gt_doc FROM gs_doc TRANSPORTING flag WHERE flag = ' '. ENDCASE. gr_alv->refresh( ). ENDFORM.
