gtk-tree-view-column-sort-column-id (object)

object -- a gtk-tree-view-column object
sort-column-id -- an integer with the sort-column-id of the model to sort on

Accessor of the sort-column-id slot of the gtk-tree-view-column class.

The slot access function gtk-tree-view-column-sort-column-id gets the logical sort column ID that the model sorts on when this tree view column is selected for sorting. The slot access function (setf gtk-tree-view-column-sort-column-id) sets the logical sort column ID. Doing so makes the tree view column header clickable.
