Defining a Context Menu

The ALV Grid Control uses the context menu and assigns standard functions to it. Depending on the context, you can add self-defined functions to this menu and hide or disable preset functions.

Integration

The context menu is an instance of class CL_CTMENU. If event CONTEXT_MENU_REQUEST is triggered by the user, event parameter E_OBJECT contains a reference to the standard context menu.

Note Note

See also report BCALV_GRID_06 in development class SLIS.

Features

You can change this menu as follows:

To add an option to the menu, call method add_function:

Syntax Syntax

CALL METHOD E_OBJECT->ADD_FUNCTION
	EXPORTING FCODE = 'DELE'
	TEXT = TEXT-003. "Delete

End of the code.

To disable existing functions (and gray them out), you pass all corresponding function codes of method disable_functions in a table:

Syntax Syntax

DATA: LT_FCODES TYPE UI_FUNCTIONS,
CLEAR LT_FCODES.
APPEND CL_GUI_ALV_GRID=>MC_FC_COL_OPTIMIZE TO LT_FCODES.
APPEND CL_GUI_ALV_GRID=>MC_FC_HELP TO LT_FCODES.
CALL METHOD E_OBJECT->DISABLE_FUNCTIONS
	EXPORTING FCODES = LT_FCODES.

End of the code.

To hide existing functions, you follow the same procedure and call method hide_functions instead of method disable_functions.

With methods enable_functions and show_functions you can enable or display the relevant functions again.

Note Note

You read the function codes for self-defined functions at event user_command.
