So if I understand good, it's imppossible to have a dot line. I can't 
modify the animation with the triangle :(

Okay, in fact we create the colum first then we add the element in the 
colum. But before I do this :

 renderer = gtk_cell_renderer_pixbuf_new();
 column = gtk_tree_view_column_new_with_attributes ("image",
                            renderer,
                            "pixbuf", PIXBUF_COLUM,
                            "pixbuf_expander_open", PIXBUF_COLUM,
                            "pixbuf_expander_closed", PIXBUF_COLUM,
                            NULL);
 gtk_tree_view_append_column (GTK_TREE_VIEW (tree), column);


 renderer = gtk_cell_renderer_text_new ();
 column = gtk_tree_view_column_new_with_attributes ("Author", renderer,
                            "text", AUTHOR_COLUMN,
                            NULL);
 gtk_tree_view_append_column (GTK_TREE_VIEW (tree), column);

You said that I can use gtk_tree_view_column_new_with_attributes only 
with the first render so pixbuf in my sample. But how could I add my 
attributes for the text if use only gtk_tree_view_colum_pack_start ?

I have also an other question : Wath type of element must I use in my 
model ? Before I use :

store = gtk_tree_store_new (N_COLUMNS,
                 GDK_TYPE_PIXBUF,
                 G_TYPE_STRING,
                 G_TYPE_STRING);

but now, the two colums make only one colum so I don't know the type.

In fact, I want that all my cell of the TreeView use the "fixed" font 
and I want to use differentes color in the first colum (like you can see 
in my screenshot : http://www.arnoraes.freesurf.fr/Forum/tree.png).
