This is what I do

I understand that.

They do not answer my question, let me reask it more clearly :

I implement my own GtkTreeModel.
I want to have 2 cell renderers : pixbuf (not expandable in layout) and 
text (expandable in layout).
Each cell icon and text must be dependent on the content of the cell => 
I have to use a GtkTreeCellDataFunc.

So now, I understood that if I use a GtkTreeCellDataFunc, I can check in 
it for which cell renderer I have to put the property (I can test as the 
cell renderer is passed as argument).

Then my problem is to be able to add the pixbuf cell renderer as the 
first one and not being expandable...
Indeed, the only function I see to set my GtkTreeCellDataFunc is 
gtk_tree_view_column_set_cell_data_func(...) AND I do not see any way to 
say add this renderer WITHOUT it being EXPANDABLE :-(

Thank you again,
