    <title>Useful methods for a TreeView widget</title>

    
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 <link xref="model-view-controller.py" />.

    
In line 36 the "changed" signal is connected to the callback function on_changed() using widget.connect(signal, callback function). See <link xref="signals-callbacks.py"/> for a more detailed explanation.
