Yes, it is possible. To do things on a per row basis, use the model.
Reserve some entries in your model to tune the properties of your
renderer. Here is an example:
This is a complex set method that sets a name and a value in a treeview.
The value (a potential) can be editable or not, depending on the type
variable and its colour can also be changed. Here its visibility is
always TRUE:
gtk_tree_store_set(isosurfaces_data_list, &childIter,
NAME_COLUMN, current_surface,
POTENTIAL_COLUMN, potentialData[pos],
EDIT_POTENTIAL_COLUMN, (type == SURFACE_TYPE_FILE_DENPOT),
COLOR_POTENTIAL_COLUMN, color,
USE_POTENTIAL_COLUMN, TRUE,
-1);
The corresponding column for the potential has been declared like
this, where renderer is a text one:
column = gtk_tree_view_column_new_with_attributes
(_("Value"), renderer,
"text", POTENTIAL_COLUMN,
"editable", EDIT_POTENTIAL_COLUMN,
"foreground", COLOR_POTENTIAL_COLUMN,
"visible", USE_POTENTIAL_COLUMN, NULL);
So in that case, the model can tune per row the editable, colour and
visible properties.
The model has the following description (it has many more things than
just the potential one):
isosurfaces_data_list =
gtk_tree_store_new(N_COLUMNS, G_TYPE_INT, G_TYPE_BOOLEAN,
G_TYPE_BOOLEAN, G_TYPE_STRING, G_TYPE_STRING,
G_TYPE_BOOLEAN, G_TYPE_STRING, G_TYPE_INT,
G_TYPE_FLOAT, G_TYPE_BOOLEAN, G_TYPE_BOOLEAN,
G_TYPE_STRING, GDK_TYPE_PIXBUF, G_TYPE_INT,
G_TYPE_BOOLEAN, G_TYPE_POINTER, G_TYPE_POINTER,
G_TYPE_STRING);

PS: questions about the usage of GTK+ should be sent to
gtk-app-devel-list@gnome.org not the other one that is for the
development of GTK+ itself.
