<a name="line-39"></a><span class='hs-comment'>-- | 'TreeSortable' is an interface to be implemented by tree models which</span>
<a name="line-40"></a><span class='hs-comment'>-- support sorting. The 'TreeView' uses the methods provided by this interface</span>
<a name="line-41"></a><span class='hs-comment'>-- to sort the model. As of now, only the</span>
<a name="line-42"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.ModelView.TreeModelSort.TreeModelSort' proxy supports the</span>
<a name="line-43"></a><span class='hs-comment'>-- sortable interface. Thus, in order to enable sortable columns in a</span>
<a name="line-44"></a><span class='hs-comment'>-- 'TreeView', it is necessary to wrap a</span>
<a name="line-45"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.ModelView.ListStore.ListStore' or</span>

<a name="line-49"></a><span class='hs-comment'>-- A 'Graphics.UI.Gtk.ModelView.TreeViewColumn' can be sorted by the user</span>
<a name="line-50"></a><span class='hs-comment'>-- though clicking into the column's header. The rows in the view will then be</span>
<a name="line-51"></a><span class='hs-comment'>-- sorted by the sorting function set for that column. Specifically, a set of</span>
<a name="line-52"></a><span class='hs-comment'>-- sorting functions must be set using the interface provided in this module.</span>
<a name="line-53"></a><span class='hs-comment'>-- Each sorting function is associated with a 'SortColumnId', which is some</span>
<a name="line-54"></a><span class='hs-comment'>-- positive number. A tree view column is then associated with the sorting</span>

<a name="line-57"></a><span class='hs-comment'>-- There exists one special 'SortColumnId', namely</span>
