- CL_SALV_TABLE中提供了 GET_FUNCTIONS方法.GET_FUNCTIONS方法返回的是一个CL_SALV_FUNCTIONS_LIST类型的实例对象.
-
类CL_SALV_FUNCTIONS_LIST两个方法(SET_ALL、SET_DEFAULT)可以添加标准状态栏
-
实现步骤:
-
定义SET_STATUS私有方法.
PRIVATE SECTION.METHODS:set_status CHANGING co_alv TYPE REF TO cl_salv_table.METHOD set_status.DATA(lo_functions) = co_alv->get_functions( )."cl_salv_functions_list类型的实例对象的添加状态方法lo_functions->set_all( abap_true )."lo_functions->set_default( abap_true ).ENDMETHOD. -
在生成SALV实例对象后调用SET_STATUS私有方法.
DATA: lx_msg TYPE REF TO cx_salv_msg.TRY.cl_salv_table=>factory(IMPORTINGr_salv_table = mo_salvCHANGINGt_table = mt_data ).CATCH cx_salv_msg INTO lx_msg.ENDTRY.me->set_status( CHANGING co_alv = mo_salv ).
