cl_gui_alv_tree_simple and optimize column width

[Former Member]

Hi,

I'm using cl_gui_alv_tree_simple like i've seen in the program 'BCALV_TREE_SIMPLE_DEMO'

and like in the demo the columns dont apear optimized for the width of it's content.

How can I do this?

edit

in the code we can found this

* optimize column-width
  CALL METHOD tree1->column_optimize
    EXPORTING
      i_start_column = tree1->c_hierarchy_column_name
      i_end_column   = tree1->c_hierarchy_column_name.

but it seems to do nothing...

You need to give the column name of type LVC_FNAME.

CALL METHOD tree1->column_optimize

EXPORTING

I_START_COLUMN = nnnnnnnnnnnnnn

I_END_COLUMN = nnnnnnnnnnnn

I_INCLUDE_HEADING = 'X'

EXCEPTIONS

START_COLUMN_NOT_FOUND = 1

END_COLUMN_NOT_FOUND = 2

others = 3

can u be more specific? i dont understant what you mean

Forget the above post. you need to make the changes in field catalog..

in field catalog set this property.

ls_fieldcatalog-outputlen = '12'. *12 is the length of that column.

The above post would set the column width to a static width, which, I don't think is what you are looking for.

Try this:

ls_fieldcat-COL_OPT = 'X'

where ls_fieldcat is defined as:

DATA: ls_fieldcat TYPE lvc_s_fcat.

and you are in a loop through your field catalog.
