<!-- ##### SECTION Title ##### -->
GtkCTree

<!-- ##### SECTION Short_Description ##### -->
a widget displaying a hierarchical tree.

<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkCTree widget is used for showing a hierarchical tree 
to the user, for example a directory tree.
</para>
<para>
The tree is internally represented as a set of #GtkCTreeNode structures.
</para>
<para>
The interface has much in common with the #GtkCList widget: rows (nodes)
can be selected by the user etc.
</para>
<para> 
Positions in the tree are often indicated by two arguments, a
parent and a sibling, both #GtkCTreeNode pointers. If the parent
is %NULL, the position is at the root of the tree and if the sibling
is %NULL, it will be the last child of parent, otherwise it will be
inserted just before the sibling.
</para>

<!-- ##### SECTION See_Also ##### -->
<para>

</para>

<!-- ##### STRUCT GtkCTree ##### -->
<para>
The #GtkCTree-struct contains the following user-accessible fields.
These fields should be considered read-only; to set the values,
use the methods below.
