Re: Treeview with images problem

Make sure you create the model with the right types first  Even though 
you are using one column, you are effective packing what would be two 
columns normally into one.  To do this you still need a type in the 
model to support each part packed into the column:

**** code ****

/* columns */
enum
{
 COL_IMAGE = 0,
 COL_NAME,
 COL_COUNT
};

void populate()
{
GtkTreeStore *model;

 /* create tree store */
 model = gtk_tree_store_new(COL_COUNT,
                GDK_TYPE_PIXBUF,
                G_TYPE_STRING);

     if(model != NULL)
       {
         GtkTreeIter iter;

         gtk_tree_store_append(model, &iter, NULL);
         gtk_tree_store_set(model, &iter,
                COL_IMAGE, imageNewFromFile(FILE_GROUPS),
                COL_NAME, name,
                -1);


       }
}

GdkPixbuf *imageNewFromFile(const gchar *filename)
{
 GtkWidget *image;

 if(filename == NULL || strlen(filename) < 1)
   {
     g_warning("imageNewFromFile: filename was NULL");
     return NULL;
   }

 image = gtk_image_new_from_file(filename);

 if(image == NULL)
   g_warning("imageNewFromFile: image was NULL");

 return gtk_image_get_pixbuf(GTK_IMAGE(image));
}

****

I hope this helps,
