classes inside function module.

[Former Member]

Hi,

how to use class definition(OOPS) concept inside the FM.

i have an internal table in the function module which is local to this FM now i want to display that table in an ALV from the function module. i want to use OOPS concept for since i have some requirements also which is based on OOPS concept.

If any one know about this, kindly share me how to do it.

thanks and regards,

Hi,

u can call the predefined classes inside the function module.

do the coding for displaying ALV through OOPS using docking controller.

hi,

may i know what is this docking controller.

Hi,

you can link controls to a screen using a SAP Docking Container. This is encapsulated in the global class CL_GUI_DOCKING_CONTAINER. The SAP Docking Container does not place the control within a screen. Instead, it attaches it to one of the four edges. You can nest containers. For example, you can use the SAP Splitter Container (classes CL_GUI_EASY_SPLITTER_CONTAINER or CL_GUI_SPLITTER_CONTAINER) within other containers. This allows you to split a custom control or docking control into more than one area, allowing you to embed more than one control.

example code:

DATA : g_dock TYPE REF TO cl_gui_docking_container,
g_split TYPE REF TO cl_gui_easy_splitter_container,
g_cont1 TYPE REF TO cl_gui_container,
g_cont2 TYPE REF TO cl_gui_container,
g_grid1 TYPE REF TO cl_gui_alv_grid,
g_grid2 TYPE REF TO cl_gui_alv_grid.


data:i_mara type mara occurs 0 with header line.
data:i_kna1 type kna1 occurs 0 with header line.

* i_mara is an internal table of structure MARA
SELECT * FROM mara INTO TABLE i_mara.

* i_kna1 is an internal table of structure KNA1

SELECT * FROM kna1 INTO TABLE i_kna1.

* To create an Object of type Docking Container

CREATE OBJECT g_dock
EXPORTING
side = cl_gui_docking_container=>dock_at_top
extension = 200 .

* To Create an Object of Type Split Container. Here we can see that the Docking
*Container Created above has been used as a parent .

CREATE OBJECT g_split
EXPORTING
parent = g_dock
orientation = 1 .

* Easy Split container splits one Control into 2 manageable controls, each of them is used
* to handle one GUI Container each

g_cont1 = g_split->top_left_container.
g_cont2 = g_split->bottom_right_container.

* To Create an Object of type Grid . Here we can see that the Left Split Container
* Created above has been used as a parent .

CREATE OBJECT g_grid1
EXPORTING
i_parent = g_cont1 .

* To Create an Object of type Grid . Here we can see that the Right Split Container
* Created above has been used as a parent .

CREATE OBJECT g_grid2
EXPORTING
i_parent = g_cont2 .

* The method of Grid Control Object is used to display the Data.

CALL METHOD g_grid1->set_table_for_first_display
EXPORTING
i_structure_name = 'MARA'
CHANGING
it_outtab = i_mara[] .

* The method of Grid Control Object is used to display the Data.

CALL METHOD g_grid2->set_table_for_first_display
EXPORTING
i_structure_name = 'KNA1'
CHANGING
it_outtab = i_kna1[] .
