I realized I had two buttons that both need to be unsensitive when
there's no selection, and having two connect lines each making their
own lambda seemed really inefficient, so I refactored it into this:
def selection_changed(self, selection, data=None):
sensitivity = selection.count_selected_rows() > 0
self.apply_button.set_sensitive(sensitivity)
self.delete_button.set_sensitive(sensitivity)
...
self.treeview.get_selection().connect("changed", self.selection_changed)
Thanks!
