[Former Member]

Hi all,

I import test.gif to my webdynpro component.

I want show my icon in table and alv table.

Table is ok, but alv table don`t display icon in column.

Here is my code:

  lo_column_settings ?= lo_value.
  lt_columns = lo_column_settings->get_columns( ).
    LOOP AT lt_columns ASSIGNING <fs_col>.
    CASE  <fs_col>-id.
      when 'TEST'.
           create object lo_image.
           lo_image->SET_SOURCE( 'objtp_mer.gif' ).
           <fs_col>-r_column->set_cell_editor( lo_image ).
      ENDCASE.
ENDLOOP.

The MIMEs are stored in the MIME repostory in "Folders" according to the WD Component, not the application. Therefore when you use ALV, the ALV Component is a separate Component. You can't reference you component specific image without supplying the path as well.

Change the reference to something like this:

../<Your WD Component>/'objtp_mer.gif

Unfortunately, Thomas.

ZALV is my wd component.

I found problem in CL_WDR_UTILITIES=>CONSTRUCT_MIME_URL

If url icon is

'/zalv/objtp_mer.gif'

this method return the same and icon don`t display.

But if method return

~zalv/objtp_mer.gif 

i see icon in alv.

How i can get back ~zalv/objtp_mer.gif?

~zalv/objtp_mer.gif isn't really a URL. It is just a shortcut name to identify the component. I wouldn't expect CL_WDR_UTILITIES=>CONSTRUCT_MIME_URL to return that. However if it works why worry with CL_WDR_UTILITIES=>CONSTRUCT_MIME_URL. Just concatenate ~, the WD Component, /, and the image name.

I wouldn't have expected '/zalv/objtp_mer.gif' to work. You would be saying that /ZALV/ is a sub-folder of the ALV component. You would the .. to say you are going up a folder.

Sorry, i don`t understand.

Before writing on sdn i tried ~/ZALV/objtp_mer.gif

An exception occurred which is explained in detail below.
The exception, which is assigned to class 'CX_WDG_UR_WEB_ICON_EXCEPTION', was
 not caught and
therefore caused a runtime error.
The reason for the exception is:
Es existiert kein WebIcon mit dem Alias "~/ZALV/objtp_mer.gif"

call stack in dump

 
40 METHOD       CL_WDG_UR_WEB_ICON_REPOSITORY=CP    CL_WDG_UR_WEB_ICON_REPOSITORY=CM008    19

   CL_WDR_UTILITIES=>CONSTRUCT_MIME_URL

couse dump in table wdg_ur_web_icon, where no record.

in debuger in CONSTRUCT_MIME_URL i change R_URL on ~/ZALV/objtp_mer.gif and icon fine display.
