實(shí)現(xiàn)：

1、add：

?2、delete

3、add2

實(shí)現(xiàn)步驟：

1、新建屬性display_text

2、創(chuàng)建layout

3、代碼部分：

add事件：

METHOD onactionadd .DATA: ls_disp TYPE string.wd_context->get_attribute(EXPORTING name = 'DISPLAY_TEXT'IMPORTING value = ls_disp ).CONCATENATE ls_disp 'Action1' into ls_disp.wd_Context->SET_ATTRIBUTE( name = 'DISPLAY_TEXT' value = ls_disp ).ENDMETHOD.

add2事件：

method ONACTIONADD2 .data: ls_disp type string.wd_Context->get_attribute(EXPORTING name = 'DISPLAY_TEXT'IMPORTING value = ls_disp ).CONCATENATE ls_disp 'Action2' into ls_disp.wd_Context->SET_ATTRIBUTE( name = 'DISPLAY_TEXT' value = ls_disp ). endmethod.

delete事件：

method ONACTIONDELETE .data: ls_disp type string.wd_Context->SET_ATTRIBUTE( name = 'DISPLAY_TEXT' value = space ). endmethod.

方法WDDOONCONTEXTMENU好像沒(méi)起作用

method WDDOONCONTEXTMENU .DATA: ls_id type string,lo_menu type REF TO cl_wd_menu,lo_menu_item type REF TO cl_wd_menu_action_item. * get the UI element IDls_id = CONTEXT_MENU_EVENT->originator->id. * if it is the 1st UI,then assign the Cotext Menu staticallyIF ls_id = 'TEXT'.MENU = CONTEXT_MENU_MANAGER->get_context_menu( 'ACTION' ).ENDIF. * if it is the 2nd UI,then assign the Cotext Menu programlyIF ls_id = 'TEXT2'. **runtime objectlo_menu = cl_wd_menu=>new_menu( id = 'ACTION2' ). **menu itmelo_menu_item = cl_wd_menu_action_item=>new_menu_action_item(id = 'ADD2'on_action = 'ADD2'text = 'Action2-Add2' ). **add this item to menulo_menu->add_item( lo_menu_item ). **menu itmelo_menu_item = cl_wd_menu_action_item=>new_menu_action_item(id = 'DELETE2'on_action = 'DELETE'text = 'Action2-DELETE2' ). **add this item to menulo_menu->add_item( lo_menu_item ). **return the menuMENU = lo_menu.ENDIF. endmethod.
