cl_gui_html_viewer method load_data

Former Member — Thu, 20 Aug 2009 10:26:05 GMT

Hi,

I use use the mentioned method to load the documentation of the program into a container. Is it possible to change the background of this? I get only a white background, what I want is a different colour.

Thanks.

Try this way:


    APPEND '<HTML>< body style="background-color:#c3d9ff;" >' TO raw_html.
    APPEND '</BODY></HTML>' TO raw_html.

check this http://html-color-codes.info/ for color information.

Hi Naimesh,

I have this coding in my report:


  CALL FUNCTION 'DOC_OBJECT_GET_HTML'
    EXPORTING
      docuid     = 'RE'
      docuobject = sy-repid
    TABLES
      html_page  = l_t_html_page.

  CREATE OBJECT html_viewer
    EXPORTING
      parent = container.

  CALL METHOD html_viewer->load_data
    IMPORTING
      assigned_url = l_f_url
    CHANGING
      data_table   = l_t_html_page.

  CALL METHOD html_viewer->show_url
    EXPORTING
      url = l_f_url.

where can I insert the background colour?

How can I look to the body tag. Shall I have to modify the first line in the hmtl table?

Loop at the table, and check each line if


CS  '<BODY>'

then use that line and statements FIND or SEARCH to get its position in a line. Next use offset specification to modify that <BODY ...> and finally modify entire line in table.

Hello Marcin,

this is my html:


<BODY BGCOLOR="WHITE" TEXT="BLACK" LINK="BLUE" VLINK="#3366CC" ALINK="RED">
<TABLE BORDER="0" CELLPADDING="2" WIDTH="100%" BGCOLOR="#3366CC"><TR><TD><FONT COLOR="#FFFFFF" SIZE="5">

</FONT></TD></TR></TABLE>
<H2>Dokumentation</H2>
<H2></H2>
<P>Einleitung:</P>
</FONT></BODY></HTML>

now I have to make:


loop at html into wa_html.
if wa_html-TDLINE cs 'BODY'.
.....
endif.
endloop.

but how can I say that he only change the value of BGCOLOR?

You can do it like


SEARCH it_html FOR 'BODY'.
IF sy-subrc = 0.
  DELETE it_html INDEX sy-tabix. "sy-tabix automatically set by SEARCH
  it_html = '< BODY style="background-color:#c3d9ff" TEXT="BLACK" LINK="BLUE" VLINK="#3366CC" ALINK="RED" >'.
  INSERT it_html INDEX sy-tabix. "new style applies here
ENDIF.

Hello Marcin,

now I have this one:


    LOOP AT l_t_html_page INTO l_r_html_page.
      SEARCH l_r_html_page FOR 'BODY'.
      IF sy-subrc = 0.
        l_r_html_page-tdline = '<BODY BGCOLOR="WHITE" TEXT="GREEN" LINK="BLUE" VLINK="#3366CC" ALINK="RED">'.
        MODIFY l_t_html_page FROM l_r_html_page.
        CLEAR l_r_html_page.
      ENDIF.
    ENDLOOP.

and it works, thanks a lot.
