To create a tree or list in GTK+, you need to use the <link
|
||
|
|
linkend="GtkTreeModel">GtkTreeModel</link> interface, in
|
||
|
|
conjunction with the <link
|
||
|
|
linkend="GtkTreeView">GtkTreeView</link>.

Here is a simple example of using a <link
|
||
|
|
linkend="GtkTreeView">GtkTreeView</link> widget in context of the
|
||
|
|
other widgets. It simply creates a simple model and view, and
|
||
|
|
puts them together. Note that the model is never populated with
|
||
|
|
data — that is left as an exercise for the reader.
