You may want to take a look at the way GtkCellRenderers [1] work.
Before rendering a particular row, your tree view sets the attributes 
registered with
gtk_tree_view_insert_column_with_attributes on the cell renderer based 
on the column data you specified, afterwards requesting a render. The 
properties  not registered with the GtkTreeView are used for rendering 
but not modified by the tree view.
For instance for getting bold text, you can set the "weight" attribute 
of the cell renderer to PANGO_WEIGHT_BOLD,
and add a new boolean column to your model which is passed as 
"weight-set" attribute column inside the treeview registration call.
If you don't want to mess around with additional columns, and your 
"weight-set" value depends on the state of some object, you can also use


     gtk_tree_view_insert_column_with_data_func for the column and
     manually set all the attributes based on the object state.
