Sets the default comparison function used when sorting to be <em class="parameter"><code>sort_func</code></em>.  
If the current sort column id of <em class="parameter"><code>sortable</code></em> is

This means that once the model  has been sorted, it can't go back to the
default state. In this case, when the current sort column id of <em class="parameter"><code>sortable</code></em> is
GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.</p>
