Description Sebastian Pölsterl 2008-08-24 11:04:17 UTC 
I can call gtk.TreeView() without any argument and it works, but if I call gtk.TreeView(None) it doesn't and gives a TypeError:

TypeError: could not convert parameter 'model' of type 'GtkTreeModel'

This is especially annoying if you want to sub-class gtk.TreeView

class MyTreeView(gtk.TreeView):

    def __init__(self, model=None):
         gtk.TreeView.__init__(self, model) # Won't work if model is None

         ....
Comment 1 Paul Pogonyshev 2008-08-25 19:07:06 UTC 
This is not specific to gtk.TreeModel actually.  Patch in a minute.
