I ran into this problem again recently and finally solved it. Google turned
up my old post, so I will post the resolution in case it helps someone else.
The error in the above code is my use of the "add_with_viewport" method.
Since a treeview has native scrolling capability, I should have used the
"add" method instead (see
http://www.pygtk.org/docs/pygtk/class-gtkscrolledwindow.html#method-gtkscrolledwindow--add-with-viewport).
Making that change to the code above fixes it!
HTH,
Karl

[pygtk] Seg. fault
Hello, First, let me which you all the best for 2009. Second, my apologies for cross-posting, but I have a problem under PyGTK on the maemo plateform, and I need some advices. As you know, I develop a program to control a panoramic head. This program runs under linux/PC, windows/PC and Nokia/maemo (some reported it also runs on Openmoko as well). But I experience a nasty problem: the program now crashes with seg. fault under maemo plateform, but runs fine under others. And I can't find what is causing this¹. My question is: how can I find what is causing this problem? Are there some tools help? As my Nokia recently died, I can't make tests anymore, so I have to ask other people, people who don't know much about linux :o/ So if you have advices... Thanks, ¹ The only strange thing I found is this warning, just before the crash: /usr/lib/python2.5/site-packages/papywizard/controller/abstractController.py:120: Warning: g_object_get_qdata: assertion `G_IS_OBJECT (object)' failed self.wTree.signal_autoconnect(self._signalDict) /usr/lib/python2.5/site-packages/papywizard/controller/abstractController.py:120: Warning: g_type_get_qdata: assertion `node != NULL' failed self.wTree.signal_autoconnect(self._signalDict) Segmentation fault -- Frédéric http://www.gbiloba.org ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
[pygtk] [Announce] PyGobject 2.16.0 (stable)
I am pleased to announce version 2.16.0 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://download.gnome.org/sources/pygobject/2.16/ What's new since PyGObject 2.15.4? - gobject.timeout_add_seconds() not found in docs (Paul Pogonyshev, #547119) - _wrap_g_output_stream_write_async not adding a reference to the buffer passed (Paul, #564102) - gio.VolumeMonitor segfaults (Gian Mario Tagliaretti, #555613) - Test if `domain' is not-null before using it to avoids segfaults (Paul, #561826) - g_output_stream_write_all use gsize instead of gssize (Gian) - add __repr__ to gio.Drive, gio.Mount and gio.Volume (Paul, #530935) - Missing AC_CONFIG_MACRO_DIR([m4]) (Loïc Minier, #551227) - Make codegen not import when corresponding argument types are not registered (Paul, #551056) - Fix typos breaking compilation (Frederic Peters #551212) - GFile load_contents methods chop data at first \0 (Jonathan Matthew, #551059) Blurb: GObject is a object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyGTK, PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject requires glib >= 2.14.0 and Python >= 2.3.5 to build. GIO bindings require glib >= 2.16.0. cheers -- Gian Mario Tagliaretti GNOME Foundation member gia...@gnome.org ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

[pygtk] need pygtkspell help
Hi, I am new to gtk and python.I am in a process of developing a spell checker(for my local language-Tamil) plug in for gedit. Recently i came to know about* pygtkspell* ,which can "underline misspelled words","give suggestions on right clicking the misspelled word". But could not find out any useful links about pygtkspell. It will be helpful, if some one can point out useful links or details about pygtkspell(Basically i need small example program) -- Yours, S.Selvam ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
