How to correlate gtk.ListStore items with my own models

I have a list of Project objects, that I display in a GtkTreeView. I am trying to open a dialog with a Project's details when the user double-clicks on the item's row in the TreeView.

Right now I get the selected value from the TreeView (which is the name of the Project) via get_selection(), and search for that Project by name in my own list to corelate the selection with my own model.

However, this doesn't feel quite right (plus, it assumes that a Project's name is unique), and I was wondering if there is a more elegant way of doing it.

What I ended up doing was extending gtk.ListStore and use my custom list. I also hijacked the append() method so that not only it will append a [str, str, etc] into the ListStore, but also the actual model inside a custom list property of the class that extends ListStore.

Then, when the user double clicks the row, I fetch the requested model by the row's index in the ListStore, which corresponds to the model's index in the custom list.

Not with the default models. You could try using Py-gtktree models written specifically to use the same objects in backend and presentation.

Its documentation outlines an alternative way to make this work with standard models (i.e. without using Py-gtktree at all), by the way, but I wouldn't call it elegant.
