In CL_GUI_SPLITTER_CONTAINER ALV list is not show in called screen

Question

Hello experts,
i come across a problem while using the class:CL_GUI_SPLITTER_CONTAINER ,
my codes is as follows:
data:declarations is as follows:
             data:gr_spliter     TYPE REF TO cl_gui_splitter_container,
                     gr_container1  TYPE REF TO cl_gui_container,
                     gr_container2  TYPE REF TO cl_gui_container,
                     gr_grid1       TYPE REF TO cl_gui_alv_grid,
                     gr_grid2       TYPE REF TO cl_gui_alv_grid,
step 0  Fit  table contents:gt_out1 and gt_out2
step 1:   CREATE OBJECT gr_spliter
               EXPORTING
               parent            = cl_gui_container=>screen0
               ows               = 1
               columns         = 2
step 2:  CALL METHOD gr_spliter->get_container
             EXPORTING
             row       = 1
            column    = 1
            RECEIVING
            container = gr_container1.
            CALL METHOD gr_spliter->get_container
             EXPORTING
             row       = 1
            column    = 2
            RECEIVING
            container = gr_container2.
step 3 :call screen 100 to show ALV.
in the screen's PBO ,i show ALV using CL_GUI_ALV_GRID,the codes is:
   CREATE OBJECT gr_grid1
    EXPORTING
      i_parent          = gr_container1
   CREATE OBJECT gr_grid2
    EXPORTING
      i_parent          = gr_container2
  CALL METHOD gr_grid1->set_table_for_first_display
    EXPORTING
      i_structure_name              =  Structure of table Gt_OUT1
    CHANGING
      it_outtab                     = gt_out1
CALL METHOD gr_grid2>set_table_for_first_display
    EXPORTING
      i_structure_name              =  Structure of table Gt_OUT2
    CHANGING
      it_outtab                     = gt_out2
But after activing the program ,there is no ALV show in screen 100,I debug the program and find that
all the above object have been created corredtly.
if i create a custom contol named 'CONTAINER',and at Step 1 change the parent's value to 'CONTAINER',
then i could see the ALV　whick i hope in screen 100.
If i create a custom control in screen 100, the size of the alv will be different across different computer,
is it possible to use CL_GUI_CONTAINER=>screen0 as cl_gui_splitter_container's attribute parent  value???
and i find that there are 10 attributes named screen0 to screen9 in class CL_GUI_CONTAINER,will you tell me the usage of
these attributes?
now i only konw that ,you could set a containers parent value to be CL_GUI_CONTAINER=>screen0,which you do't have to create
a custom control in your screen ,and the alv will be shown in full screen.and what the other attributes use (screen1,screen2,screen3,screen4 and so on)
now i am confused with the problem,i am sure any words from you will give me help to this question!
Hope to receive your advice!
Best regards!
yours Carl

Dear Carl,
I mean go to screen painter and place there CUSTOM_AREA (the icon with C letter). In program's PBO create CUSTOM_CONTAINER
module pbo output.
if custom_container is initial.
CREATE OBJECT custom_container
   EXPORTING container_name = 'CUSTOM_AREA'.\
endif.
endmodule.
Then you work only with CUSTOM_CONTAINER (i.e. as parent to SPLITTER_CONTAINER). Using subscreens here doens't really add the value, so you don't need any.
But how could i stretch the screen and this area to full screen?is it just gragging the screen to full screen and drag the subscreen or the custom control to full screen in screen painter?
Yes, this is what I mean
