CL_GUI_ALV_GRID 取消右鍵功能

在網上看到有人問到這個技術怎麼做，一時興起就做起來了

首先宣告EVENT_RECEIVER

DATA: GRID TYPE REF TO CL_GUI_ALV_GRID,

EVENT_RECEIVER TYPE REF TO LCL_EVENT_RECEIVER.

再寫code，重點在event CONTEXT_MENU_REQUEST，將E_OBJECT清空

CLASS LCL_EVENT_RECEIVER DEFINITION.
PUBLIC SECTION.
METHODS:
HANDLE_CONTEXT_MENU_REQUEST FOR EVENT CONTEXT_MENU_REQUEST OF CL_GUI_ALV_GRID
IMPORTING E_OBJECT.
ENDCLASS.

CLASS LCL_EVENT_RECEIVER IMPLEMENTATION.
METHOD HANDLE_CONTEXT_MENU_REQUEST.
CALL METHOD E_OBJECT->CLEAR.
ENDMETHOD.
ENDCLASS.

再來就是將event掛到grid去

CREATE OBJECT EVENT_RECEIVER.
SET HANDLER EVENT_RECEIVER->HANDLE_CONTEXT_MENU_REQUEST FOR GRID1.
