  • SALV_T_ROW

GET_SELECTED_COLUMNS：获取 ALV 中选中的列

  • SALV_T_COLUMN

GET_CURRENT_CELL：获取 ALV 中当前选中的单元格

  • SALV_S_CELL

选择模式

CL_SALV_SELECTIONS 中的 set_selection_mode 可以设置ALV的选择模式：

  • if_salv_c_selection_mode=>row_column

if_salv_c_selection_mode

  • SINGLE：单行选择
  • MULTIPLE：多行选择
  • CELL：单元格选择
  • ROW_COLUMN：行，列选择
  • NONE：无，不能选择
*$*$*.....CODE_ADD_1 - Begin..................................1..*$*$*

    METHODS: set_selection
      CHANGING co_alv TYPE REF TO cl_salv_table.
*$*$*.....CODE_ADD_1 - End....................................1..*$*$*

*$*$*.....CODE_ADD_2 - Begin..................................2..*$*$*
  CALL METHOD set_selection
    CHANGING co_alv = gr_table.

*$*$*.....CODE_ADD_3 - Begin..................................3..*$*$*
  METHOD set_selection.
    DATA: lr_selections TYPE REF TO cl_salv_selections.
    lr_selections = co_alv->get_selections( ).
    "set selection mode"
    lr_selections->set_selection_mode( if_salv_c_selection_mode=>row_column ).
  ENDMETHOD.                    "set_selection"
