ALV OO using cl_gui_alv_grid

Former Member — Fri, 21 Nov 2008 06:47:36 GMT

Hello all,

I'm totally new to OOP so I hope anyone can help me.

I'm using the code below for displaying a layout entered on de selection screen.

*Data declaration

Data: gr_variant TYPE REF TO cl_gui_alv_grid,

gs_variant type disvariant.

*Set layout functions ALV

gr_variant = gr_table->get_variant( ).

gr_variant->get_variant( gs_variant ).

gr_variant->SAVE_VARIANT( save ).

When I'm trying to activate the program it tells me that "get_variant" doesn't exists....

When I double click on "cl_gui_alv_grid" I can find method "Get_variant".

Whats wrong?

knd rgds,

Patrick

Hello Pat,

I think you missed this stmt:

CREATE OBJECT gr_variant.

Plz try this & hope this will help.

Hello Suhas,

Thx for the quick reply.

I'm changing an existing program and for other ALV settings they didn't use "Create object". See below code:

*&- ALV grid data definition

DATA: gr_table TYPE REF TO cl_salv_table,

gr_functions TYPE REF TO cl_salv_functions,

gr_display TYPE REF TO cl_salv_display_settings,

gs_layout TYPE salv_s_layout_key,

gr_layout TYPE REF TO cl_salv_layout.

----

IF NOT gt_sbr IS INITIAL.

cl_salv_table=>factory( IMPORTING r_salv_table = gr_table

CHANGING t_table = gt_sbr ).

Set ALV functions

gr_functions = gr_table->get_functions( ).

gr_functions->set_all( abap_true ).

Set display functions ALV

gr_display = gr_table->get_display_settings( ).

gr_display->set_striped_pattern( cl_salv_display_settings=>true ).

gr_display->set_list_header( lv_header_text ).

Set layout functions ALV

gr_layout = gr_table->get_layout( ).

gs_layout-report = sy-repid.

gr_layout->set_key( gs_layout ).

gr_layout->set_save_restriction( cl_salv_layout=>restrict_none ).

*&- Output ALV

gr_table->display( ).

ELSE.

MESSAGE text-t01 TYPE 'I'.

ENDIF.

Hello Pat,

If you see the stmt


cl_salv_table=>factory( IMPORTING r_salv_table = gr_table
CHANGING t_table = gt_sbr ).

The method FACTORY of the class CL_SALV_TABLE is used to "Get New Instance for ALV Table Object".

Inside this method there is a stmt


  create object r_salv_table
    exporting
      display_object = l_display_object
      r_container    = r_container
      container_name = container_name.

So the methos FACTORY creates an instance of CL_SALV_TABLE. But for CL_GUI_ALV_GRID you have to do this in the code.

Hope this helps.

BR,

Suhas

hi,

Please check the attached code:

DATA:alv_grid TYPE REF TO

cl_gui_alv_grid.

CREATE OBJECT ALV_GRID

EXPORTING

I_PARENT = G_CUS_CONTAINER.

MOVE GS_VARIANT TO LS_VARIANT.

CALL METHOD ALV_GRID->GET_VARIANT

IMPORTING

ES_VARIANT = LS_VARIANT

E_SAVE =

Ok, as said before I'm totally new to OOP so what is G_CUS_CONTAINER?

LS_VARIANT is the same as GS_VARIANT?
