I have a treeview, with some elements in it.
How can I get a list of all this data?
Is there something similar to this,
I'd say you get the model:
model = self.treeview.get_model()
And then you have tons of different ways to access your data/items depending on what you want and how the model look... For more on that check http://pygtk.org
You could get first row by doing:
And also you could iterate through it...
