[pygtk] libglade bug?
Hi, I have this code being called every few minutes by a gkt timeout function: print = print Count = + str(self.check_count) self.check_count += 1 print self.wtree.get_widget(label_checkbutton) print = if self.wtree.get_widget(label_checkbutton).get_active(): some code cut It has been working fine for a very long time, then I upgraded to ubuntu 9.04, and started getting this error: AttributeError: 'NoneType' object has no attribute 'get_active' And here is the output prior to the error: = Count = 41 gtk.CheckButton object at 0x97909dc (GtkCheckButton at 0x9806910) = = Count = 42 gtk.CheckButton object at 0x97909dc (GtkCheckButton at 0x9806910) = = Count = 43 gtk.CheckButton object at 0x97909dc (GtkCheckButton at 0x9806910) = = Count = 44 None = Some times it fails first run, somtimes after 3 or 4 iterations, other times it goes for hours... Any clues? am I calling the get_active incorectly? -- Rob Brown-Bayliss r.brown.bayl...@gmail.com ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

It has been working fine for a very long time, then I upgraded to ubuntu
9.04, and started getting this error:
AttributeError: 'NoneType' object has no attribute 'get_active'
It's very likely a case of bug #546802,
http://bugzilla.gnome.org/show_bug.cgi?id=546802
A known workaround is to access the dict of the widget, simply using:
self.wtree.__dict__
self.wtree.get_widget('label_checkbutton')__dict__
Does anyone know if the latest PyGTK has this bug fixed? We encounter
it frequently during in-house development.

Re: [pygtk] libraries for Python isometric cad drawings

For printable/SVG output, you could use gluProject and feed your 2D-projected vertices to Cairo alongside your OpenGL code. I have used GL2PS before to make vector drawings from OpenGL, but it is in C. Thanks for the pointers Karl, much appreciated. I'll let you know if I get this thing off the ground :-) -- Darren Good luck!

I'd like to be able to render the cabinet on the screen and also print the rendering. I'm mostly just looking for a black and white line drawing for now. Can anyone recommend a higher level library for this or is PyOpenGL most likely the best bet? Or perhaps rolling my own using cairo?
