Re: Remove multiple rows from a sorted TreeView

Sorry, that should be model.

the faq has been updated.  

I have never tried to delete multiple entries on a sorted model.  I
would try converting all the iters before removing any:

 selection = treeview.get_selection()
 sorted_model, selected = selection.get_selected_rows()
 model = sorted_model.get_model()
 iters = [sorted_model.convert_iter_to_child_iter(None,
sorted_model.get_iter(path)) for path in selected]
 for iter in iters:
    model.remove(iter)
