CL_SALV_TREE : How to set its hierarchy icon & Columns settings

[Former Member]

Dear all,

Now I am programming a report which should use ALV tree to display some hierarchical information. In order to make it more intuitionistic to be read, I want to set relevant icons for some nodes in hierarch item of the tree. But, I found some problem as follows:

1. I have set a icon for the node's hierarchy item, but it can't be display while running the report.

2. Some nodes' icons are displayed, but it exists a folder icon in front of the user defined icon. How can I hide this folder icon?

In addition, I found that only the short text for column is displayed despite I have set long, medium and short text for relevant column already. I don't know where is the problem.

It's very urgent for me! Looking forward to receiving your helps!

Thanks,

Justin - Xiongjunwen

Hello Justin

For displaying user-defined icons instead of the folder icons I modified the sample report SALV_DEMO_TREE_FUNCTIONS as following:

*&---------------------------------------------------------------------*
*& Report  SALV_DEMO_TREE_FUNCTIONS
*&
*&---------------------------------------------------------------------*
*&
*&
*&---------------------------------------------------------------------*

REPORT  ZUS_SDN_SALV_DEMO_TREE_FUNC_1.



type-pools: icon.

constants:
  gc_icon_detail    type SALV_DE_TREE_IMAGE  value '@3R@',
  gc_icon_overview  type SALV_DE_TREE_IMAGE  value '@3Q@'.
...

*&---------------------------------------------------------------------*
*&      Form  add_carrid_line
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*      -->P_LS_DATA  text
*      -->P_0516   text
*      <--P_L_CARRID_KEY  text
*----------------------------------------------------------------------*
FORM add_carrid_line  USING    P_LS_DATA type alv_t_t2
                               p_key
                      CHANGING P_L_CARRID_KEY.

  data: nodes type ref to cl_salv_nodes,
        node type ref to cl_salv_node,
        text type lvc_value.

*... §0 working with nodes
  nodes = gr_tree->get_nodes( ).

  try.
*  ... §0.1 add a new node
**    node = nodes->add_node( related_node = p_key
**                            relationship = cl_gui_column_tree=>relat_last_child ).

node = nodes->add_node( related_node = p_key
relationship = cl_gui_column_tree=>relat_last_child
collapsed_icon = gc_icon_overview
expanded_icon = gc_icon_detail ).

*  ... §0.2 if information should be displayed at
*    the hierarchy column set the carrid as text for this node
    text = p_ls_data-carrid.
    node->set_text( text ).

*  ... §0.3 set the data for the nes node
    node->set_data_row( p_ls_data ).

    P_L_CARRID_KEY = node->get_key( ).
  catch cx_salv_msg.
  endtry.

ENDFORM.                    " add_carrid_line

Hello Justin

Forgot to mention that you can use report <b>RSTXICON</b> to get a list of the icons and their codes.

Hello Justin

In order to modify the column texts (long, medium) you have to do the following (see routine <b>SET_COLUMNS_TECHNICAL</b> in sample report <b>SALV_DEMO_TREE_FUNCTIONS</b>) :

  data: 
    lo_columns type ref to cl_salv_columns,
    lo_column  type ref to cl_salv_column.

   lo_columns = gr_tree->get_columns( ).
   lo_column   = lo_columns->get_column( <your column name> ).
 
   lo_column->set_long_text( <your long text> ).
   lo_column->set_medium_text( <your medium text> ).

Regards

Uwe
