Thank you for your explanation. That was my error in reasoning.

This code has helped me to rewrite it in python. See the attachment.
Thank you :) You helped me a lot.

I have only a small logic problem. I have to call a renderer in
append_column - None as in the documentation won't work.

column = selector.append_column(store_icons, renderer) #i have to call a
renderer, not None

And the application raises a warning

multi_cells_example.py:21: GtkWarning:
gtk_tree_view_column_cell_layout_pack_start: assertion `!
gtk_tree_view_column_get_cell_info (column, cell)' failed
  column.pack_start(renderer, 0)

but the application works :)

Probably you are right. I should edit the data so that it fit into the
list. I can edit the size, too.

The last problem is, if it is possible to place a gtk.Entry field on the
hildon-desktop. I get no focus in it. Perhaps the hildon-desktop is only
clickable? I have only seen a solution where a seperate dialog will
popup.

with kind regards
