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.
