Hi,
I'm trying to use the Gtk.TreeModelFilter and its "modify" function and
I'm struggling trying to make a simple example. (using PyGObject 3.10.2)
I've got something along this at the moment:
def modify_func(model, iter, value, column, user_data):
print(model, iter, value, column, user_data)
store = Gtk.ListStore(SomeObject)
model = Gtk.TreeModelFilter(child_model=store)
model.set_modify_func((int, str, str), modify_func)
I made on top of this and here is what I got printed when the view tries
to access the model:
(<TreeModelFilter object at 0xb5db5e3c (GtkTreeModelFilter at 0xa53e470)>,
<GtkTreeIter at 0xa62ba60>, 0, 0, None)
(<TreeModelFilter object at 0xb5db5e3c (GtkTreeModelFilter at 0xa53e470)>,
<GtkTreeIter at 0xa62c180>, None, 1, None)
etc...
I suspected "value" wasn't needed, but Gtk complains otherwise. So I
though it would be a GValue which I would have to set, but it's actually
a plain Python integer. Returning something from this function doesn't
help either (ie. it doesn't do anything).
So, how am I supposed to work with set_modify_func()?
Thanks,
Jonathan
