Returning 0 is wrong here, because it denotes that both elements are
equal, and no sorting will take place for this element. Rather use:
static int
my_cmp_func (GtkTreeModel *model,
GtkTreeIter *a,
GtkTreeIter *b,
MyType *first_element)
{
MyType *element_a, *element_b;
gtk_tree_model_get (model, a, MY_ELEMENT_COLUMN, &element_a, NULL);
gtk_tree_model_get (model, b, MY_ELEMENT_COLUMN, &element_b, NULL);
if (element_a == element_b) {
return 0;
}
if (element_a == first_element) {
return -1;
}
if (element_b == first_element) {
return 1;
}
/* other sorting */
}
