This TreeView displays a TreeStore with two columns, one of which is rendered as a toggle.
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 48 the "toggled"
signal is connected to the callback function on_toggled()
using widget.connect(signal, callback function)
. See for a more detailed explanation.
