No, but there aren't any "pygtk vs gtk properties". PyGTK properties

create python properties for each GObject property.
Yes I understand. What is with style properties (rw and ro)
I don't see what
you mean by "that could be handled at class level in the
__getattribute__ method".
The problems you described below.
Also please note that the use of __slot__ is bad as it impedes
defining new instance attributes in a subclass' __init__.
The problem I'm describing is not specific to PyGTK properties. All
python properties have this problem, if not see:
This works:
------------------------------------
class Foo(object):
def get_xxx(self):
print "DO SOMETHING"
return self.__xxx
def set_xxx(self, val):
print "DO SOMETHING ELSE"
self.__xxx = val
#xxx = property(get_xxx, set_xxx)
class Bar(Foo):
def __init__(self):
Foo.__init__(self)
self.xxx = 123
Bar()
------------------------------------
Now try uncommenting the xxx property definition. Then you suddenly
get "DO SOMETHING ELSE" printed on the console. For that reason,
label.text will not be supported; that is not even up for discussion.
Unless you know some trick that I don't to make this work. But note
that custom workarounds in pygtk code for property X or Y don't count.
The code must remain absolutely generic. If you upgrade gtk and not
pygtk, new properties may appear underneath you, and that is
intentional.
Your suggestion could be broken too. What is if properties will be
removed in the upgraded gtk?
So, it looks like now the only two candidates are label.props.text and
label.properties.text. Regarding the use of 'properties', I'd like to
point out that it is difficult to write with correct spelling for
non-english native speakers, thus I prefer props.
Regards.
This is not clean. There could be a list of properties (like
get_properties in libxml2) but one property will be a prop, in my point
of view.
