ALV默认提供了一些标准的功能选择供我们来操作ALV列表,但是这些功能有可能某些是我们不需要用的,想把它隐藏掉,或者某些功能无法做到,就得自定义功能按钮。
一、去掉不必要的功能按钮
REUSE_ALV_GRID_DISPLAY提供了一个参数it_exculding来去掉你不想要的ALV功能。
FORM set_func_exculding TABLES pt_extab TYPEslis_t_extab.
DATA lwa_extabLIKE LINE OF pt_extab.
lwa_extab-fcode ='%SL'.
APPEND lwa_extabTO pt_extab.
ENDFORM. "set_status_exculding
二、自定义功能按钮
REUSE_ALV_GRID_DISPLAY有一个参数i_callback_pf_status_set用来设置ALV列表指定的GUI Status。还有一个参数i_callback_user_command用来设置用户自定义的功能动作。
1. 首先要自己创建一个GUI Status,并设置好自定义按钮
2. 设置ALV使用自己创建的GUIStatus。
FORM set_pf_status USING rt_extab TYPE slis_t_extab.
SET PF-STATUS'SLVC_FULLSCREEN' EXCLUDING rt_extab.
ENDFORM. "set_pf_status
3. 设置用户点击自定义的功能按钮之后的动作。
FORM user_command USING r_ucomm TYPE sy-ucomm
rs_selfield TYPE slis_selfield.
DATA l_messageTYPE string.
CASE r_ucomm.
WHEN'FUNCTION'.
MESSAGEi000(ytest) WITH 'You Click Button ''My Func'''.
WHEN'&IC1'.
l_message =rs_selfield-tabindex.
CONCATENATE'Double Click,'
'Row:'
l_message
'Value:'
rs_selfield-value
'Fieldname:'
rs_selfield-fieldname

MESSAGEi000(ytest) WITH l_message.
ENDCASE.
