GTraverseType

Specifies the type of traveral performed by g_tree_traverse(), Node.traverse and Node.find. The different orders are illustrated here: - In order: A, B, C, D, E, F, G, H, I

- Pre order: F, B, A, D, C, E, G, I, H

- Post order: A, C, E, D, B, H, I, G, F

- Level order: F, B, G, A, D, I, C, E, H

Values

ValueMeaning
IN_ORDER0

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.

PRE_ORDER1

visits a node, then its children.

POST_ORDER2

visits the node's children, then the node itself.

LEVEL_ORDER3

is not implemented for [balanced binary trees][glib-Balanced-Binary-Trees]. For [n-ary trees][glib-N-ary-Trees], 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.
