abap--REUSE_ALV_GRID_DISPLAY事件子过程和cl_gui_grid类的事件对应关系

一、SLIS定义的ALV的事件名称
* Events
slis_ev_item_data_expand type slis_formname value 'ITEM_DATA_EXPAND',
slis_ev_reprep_sel_modify type slis_formname value 'REPREP_SEL_MODIFY',
slis_ev_caller_exit_at_start type slis_formname value 'CALLER_EXIT',
slis_ev_user_command type slis_formname value 'USER_COMMAND',
slis_ev_top_of_page type slis_formname value 'TOP_OF_PAGE',
slis_ev_data_changed type slis_formname value 'DATA_CHANGED',
slis_ev_top_of_coverpage type slis_formname value 'TOP_OF_COVERPAGE',
slis_ev_end_of_coverpage type slis_formname value 'END_OF_COVERPAGE',
slis_ev_foreign_top_of_page type slis_formname value 'FOREIGN_TOP_OF_PAGE',
slis_ev_foreign_end_of_page type slis_formname value 'FOREIGN_END_OF_PAGE',
slis_ev_pf_status_set type slis_formname value 'PF_STATUS_SET',
slis_ev_list_modify type slis_formname value 'LIST_MODIFY',
slis_ev_top_of_list type slis_formname value 'TOP_OF_LIST',
slis_ev_end_of_page type slis_formname value 'END_OF_PAGE',
slis_ev_end_of_list type slis_formname value 'END_OF_LIST',
slis_ev_after_line_output type slis_formname value 'AFTER_LINE_OUTPUT',
slis_ev_before_line_output type slis_formname value 'BEFORE_LINE_OUTPUT',
slis_ev_subtotal_text type slis_formname value 'SUBTOTAL_TEXT',
slis_ev_context_menu type slis_formname value 'CONTEXT_MENU'.

二、和事件相关的函数
2.1 获取所有事件到内表
data ct_events type slis_t_event.
call function 'REUSE_ALV_EVENTS_GET'
exporting
i_list_type = 4
importing
et_events = ct_events
exceptions
list_type_wrong = 1
others = 2.
注意： i_list_type值说明：
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list REUSE_ALV_BLOCK_LIST_HS_APPEND
4 ＝simple gridREUSE_ALV_GRID_DISPLAY

2.2 获取所有事件名称
REUSE_ALV_EVENT_NAMES_GET

三、CL_GUI_ALV_GRID的事件和 REUSE_ALV_GRID_DISPLAY定义的子过程对应关系

CL_GUI_GRID's Event	REUSE_ALV_GRID_DISPLAY函数设置的用户定义子过程
end_of_list	callback_html_end_of_list
callback_end_of_list
print_end_of_list	callback_end_of_list
end_of_page	callback_end_of_page
top_of_page	callback_html_top_of_page
callback_top_of_page
print_top_of_page	callback_top_of_page
user_command	callback_user_command
data_changed	callback_data_changed
after_user_command	callback_user_command(注意：根据函数设置先后触发CL_GUI_GRID的"TOP_OF_PAGE"和"END_OF_LIST"事件)
before_user_command	callback_user_command
after_refresh	无,系统根据选中设置grid的行选中处理 call method gt_grid-grid->set_selected_rows exporting it_index_rows = lt_rows.
double_click	callback_user_command
hotspot_click(同double_click)	callback_user_command
subtotal_text	callback_subtotal_text
context_menu_request	callback_context_menu
