[Glade-users] glade 3.6 and user data in callback function

I have just found out, that if I use "user data" column in glade, the
object is passed, but not as a (last) user_data argument, but a widget
argument. Is this the bug you meant?

I mean, if I have a cellrenderertoggle callback like
def toggled(self, cell, path):

The cell argument would not hold a cellrenderer that fired the signal,
but actually the object I defined as user data in glade.

Now I wonder, if this is gtkbuilder or pygtk issue.

There are 2 issues at hand:
  1.) Glade doesnt do a good job of letting the user know what is
       happening with user data.

  2.) it swaps the user_data with the widget for historical reasons,
       libglade worked that way and I cant recall exactly where the
       decision was made but I suppose by default it just does the
       same as libglade to avoid complications in conversions etc.

The reason why it was originally like this dates back to
which by default swaps the user data; letting you do funky things from Glade
such as connecting symbols from GTK+ to objects without writing code
(i.e. pass "gtk_widget_hide" to a signal with user data as the widget
you want to hide
when the signal is emitted).
