Get functions method

[former_member497886]

Hello Experts

Happy new year to everyone.

Thanks for all the help till now.

I am again stuck with one of the issue. The scenario goes like this-

i am displaying full screen ALv grid output using class cl_salv_table.

I havw created a custom GUI status which has 3 buttons. I want to hide one of them based on certain condition.

following is the code which i have written-

data : lr_functions TYPE REF TO cl_salv_functions,
            lt_func_list TYPE salv_t_ui_func.

lr_functions = o_alv->get_functions( )

lt_func_list = lr_functions->get_functions( ).

the list which i get lt_func_list does not populate with all the application toolbar functions which i added.

Please help.

Thanks.

Hi,

How to use get_function:

Some code:

*----------------------------------------------------------------------*

*----------------------------------------------------------------------*

CLASS cl_event_receiver DEFINITION .

  PUBLIC SECTION.

    CONSTANTS: c_select_a TYPE salv_de_function VALUE 'Select_all ' .

    CONSTANTS: c_select_d TYPE salv_de_function VALUE 'Select_none' .

    METHODS added_function FOR EVENT added_function OF cl_salv_events

        IMPORTING e_salv_function .

ENDCLASS .                    "cl_event_receiver DEFINITION

*----------------------------------------------------------------------*

CLASS cl_event_receiver IMPLEMENTATION.

METHOD added_function .

* Your code....

  ENDMETHOD .

ENDCLASS .                    "cl_event_receiver IMPLEMENTATION

*----------------------------------------------------------------------*

*----------------------------------------------------------------------*

PBO:

DATA: ob_salv_functions    TYPE REF TO cl_salv_functions .

ob_salv_functions = ob_salv_table->get_functions( ) .

DATA: icon_name TYPE string .

DATA: icon_text TYPE string .

DATA: icon_tool TYPE string .

icon_name = icon_select_all .

icon_text = 'Select All' .

icon_tool = 'Select All Rows'  .

ob_salv_functions->add_function(

name     = cl_event_receiver=>c_select_a

icon     = icon_name

text     = icon_text

tooltip  = icon_tool

position = if_salv_c_function_position=>right_of_salv_functions  ) .

icon_name = icon_deselect_all .

icon_text = 'Deselect' .

icon_tool = 'Deselect All Rows'  .

ob_salv_functions->add_function(

name     = cl_event_receiver=>c_select_d

icon     = icon_name

text     = icon_text

tooltip  = icon_tool

position = if_salv_c_function_position=>right_of_salv_functions  ) .

DATA: ob_salv_events    TYPE REF TO cl_salv_events_table.

DATA: ob_event_receiver TYPE REF TO cl_event_receiver .

ob_salv_events = ob_salv_table->get_event( ).

  CREATE OBJECT ob_event_receiver

    EXPORTING

      ob_salv_table = ob_salv_table.

SET HANDLER ob_event_receiver->added_function       FOR ob_salv_events .

Result:

Hi

for functions the ALV buffer is used (FM ALV_CHECK_BUFFER)

just reset the buffer after STATUS changes with e.g.

- Report BALVBUFDEL

- Report BCALV_BUFFER_DELETE

- FM ALV_DELETE_BUFFER

- TX /$SYNC <== !!! reset all buffer

or just set the SET/GET parameter ALVBUFFER to a future date, like:

     DATA l_tomorrow TYPE dats.
     l_tomorrow = sy-datum + 1.
     SET PARAMETER ID 'ALVBUFFER' FIELD l_tomorrow.
     gr_table->set_screen_status(
       pfstatus      = 'ALV_STATUS'
       report        = l_repid
       set_functions = cl_salv_table=>c_functions_none ).
