This TreeView displays a simple ListStore with the selection "changed" signal connected.

# Code used to generate this example

# Useful methods for a TreeView widget

The TreeView widget is designed around a Model/View/Controller design: the Model stores the data; the View gets change notifications and displays the content of the model; the Controller, finally, changes the state of the model and notifies the view of these changes. For more information and for a list of useful methods for TreeModel see .

In line 36 the `"changed"` signal is connected to the callback function `on_changed()` using `widget.connect(signal, callback function)`. See for a more detailed explanation.
