#GtkTree is deprecated and unsupported. It is known to be
|
|
buggy. To use it, you must define the symbol %GTK_ENABLE_BROKEN

prior to including the GTK+ header files. Use #GtkTreeView instead.

The #GtkTree widget is a container that shows users a list of items, in a tree format complete with branches and leafnodes. Branches can be expanded to show their child items, or collapsed to hide them.
