Leaving or hiding unnecessary screen

Question

Hi everybody,
I have created some simple gui using only objects at runtime: they are accessible from a main dialogbox container. I want to display this, but there is always an empty screen behind which shouldn't be seen.
DATA: g_custom_container TYPE REF TO cl_gui_dialogbox_container,
      splitter_easy TYPE REF to cl_gui_easy_splitter_container,
      viewer TYPE REF TO cl_gui_html_viewer.
  CREATE OBJECT g_custom_container
    EXPORTING
      name  = 'CONTAINER2'
      width = 800
      height = 300.
  CREATE OBJECT splitter_easy
      EXPORTING
      parent        = g_custom_container
      orientation   = 0
      sash_position = 95.
  CREATE OBJECT viewer
    EXPORTING
      parent   = top
      saphtmlp = 'X'.
  doc_url = somelocalpath....
  CALL METHOD viewer->show_url
    EXPORTING
      url                  = doc_url
    EXCEPTIONS
      cnht_error_parameter = 1
      OTHERS               = 2.
When i call this piece of code (this is a sample of course) from the calling program, a new empty screen is created, and over the screen the desired gui is displayed. I also tried to associate object creations to a transaction type OO (calls a method from a class i previously defined trough class builder) and then calling trough, but the result is the same.
Does anyone know why this is happening, and hopefully how to solve it? Thanks in advance.

Hi Peppone,
Once i hav used this cl_gui_dialogbox_container class to generate a popup to display some additional
information in the selection screen...no blank screens!!... it worked fine for me...
check the below example...
Here the popup comes over the sel-screen( no blank screen ) and we can also enter values(try changing
rows and click pop-up again) in the sel-screen keeping the popup open....
*Example : *
CLASS lcl_event_handler DEFINITION.
  PUBLIC SECTION.
    DATA : lv_top    TYPE i,
           lv_left   TYPE i,
           lv_height TYPE i,
           lv_width  TYPE i.
    METHODS close_popup FOR EVENT close OF cl_gui_dialogbox_container IMPORTING sender.
ENDCLASS.                    "lcl_event_handler DEFINITION
CLASS lcl_event_handler IMPLEMENTATION.
  METHOD close_popup.
    PERFORM free_controls.
  ENDMETHOD.                    "destructor
ENDCLASS.                    "lcl_event_handler IMPLEMENTATION
TABLES : sscrfields.
DATA : popup        TYPE REF TO cl_gui_dialogbox_container,
       splitter     TYPE REF TO cl_gui_splitter_container,
       transponder  TYPE REF TO lcl_event_handler,
       container1   TYPE REF TO cl_gui_container,
       html_control TYPE REF TO cl_gui_html_viewer.
PARAMETER rows TYPE i DEFAULT 2.
SELECTION-SCREEN PUSHBUTTON 60(10) name USER-COMMAND push.
INITIALIZATION.
  MOVE 'Pop-up' TO name.
AT SELECTION-SCREEN.
  CHECK sscrfields-ucomm EQ 'PUSH'.
  IF popup IS BOUND.
    PERFORM free_controls.
  ENDIF.
  CREATE OBJECT popup
    EXPORTING
      top    = 50
      left   = 600
      width  = 300
      height = 300.
  CREATE OBJECT splitter
    EXPORTING
      parent = popup.
  CREATE OBJECT transponder.
  SET HANDLER transponder->close_popup FOR popup.
  splitter->set_grid( rows = rows columns = 2 ).
  splitter->set_column_width(  id = 1 width = 50 ).
  container1 = splitter->get_container( row = 1 column = 1 ).
  splitter->set_border( '0' ).
  CREATE OBJECT html_control
    EXPORTING
      parent = container1.
FORM free_controls.
  FREE container1.
  popup->free( ).
  CLEAR popup.
ENDFORM.                    "free_controls
Cheers,
Jose.
