- * GTraverseType:
- * @G_IN_ORDER: vists a node's left child first, then the node itself,
- * then its right child. This is the one to use if you
- * want the output sorted according to the compare
- * function.
- * @G_PRE_ORDER: visits a node, then its children.
- * @G_POST_ORDER: visits the node's children, then the node itself.
- * @G_LEVEL_ORDER: is not implemented for <link
- * linkend="glib-Balanced-Binary-Trees">Balanced Binary
- * Trees</link>. For <link
- * linkend="glib-N-ary-Trees">N-ary Trees</link>, it
- * vists the root node first, then its children, then
- * its grandchildren, and so on. Note that this is less
- * efficient than the other orders.
