html viewer

Hi all

I am trying to understand how this object works. I believe that this is a way to write my own html page and see it in a dynpro.

This is the code I wrote:

" declaration of object
DATA html_viewer TYPE REF TO cl_gui_html_viewer.
" container
DATA g_custom_container TYPE REF TO cl_gui_custom_container.
" url of doc created
DATA l_doc_url(255) TYPE c.
" dynamic HTML creation structs
DATA data_table TYPE STANDARD TABLE OF char255.
DATA wa_table LIKE LINE OF data_table.

" test
wa_table = '<h1>This is a test</h1>'.
INSERT wa_table INTO TABLE data_table.

" create container
CREATE OBJECT g_custom_container
  EXPORTING
    container_name = 'CONTAINER'.
" create html viewer
CREATE OBJECT html_viewer
  EXPORTING
    parent     = g_custom_container.
" load data on server
CALL METHOD html_viewer->load_data
  EXPORTING
    type                 = 'text'
    subtype              = 'html'
  IMPORTING
    assigned_url         = l_doc_url
  CHANGING
    data_table           = data_table
  EXCEPTIONS
    dp_invalid_parameter = 1
    dp_error_general     = 2.
" show loaded data in html control
CALL METHOD html_viewer->show_data
  EXPORTING
    url = l_doc_url.

" call main screen
CALL SCREEN 10.

All works, but html is not interpreted: the result is that I see in the html control '<h.1>Test</h.1>' (Added dot to not see written as header here in the post) and not 'Test' written as header (that would be <h1>Test</h1>). Am i missing something or do I misunderstood the use of this object?

regards

Gabriele

Hello,

your problem is witjh the HTML. You need to insert the <html> tag. try this:


" test
wa_table = '<html>'.
Append wa_table TO data_table.
wa_table = '<h1>This is a test</h1>'.
append wa_table TO data_table.
wa_table = '</html>'.
Append wa_table TO data_table.

Regards,

pedro
