Details

Accessor of the expander-column slot of the gtk-tree-view class.

The slot access function gtk-tree-view-expander-column returns the column that is the current expander column. The slot access function (setf gtk-tree-view-expander-column) sets the column to draw the expander arrow at. It must be in the tree view. If column is nil, then the expander arrow is always at the first visible column.

If you do not want expander arrow to appear in your tree, set the expander column to a hidden column.
