[pygtk] making pygobject_register_sinkfunc a noop?
Hi, I'm working on pybank and have found a problem when removing the floating reference after construction. The current plan is to base pybank on pygobject, so pybank would basically create at runtime the equivalent of the code generated for the gtk, gstreamer, etc bindings. I'm wondering now how can I make the equivalent of calling pygobject_register_sinkfunc in pybank and by looking at the gjs code, seems like we don't really need for each library bindings to register their own sinkfuncs: http://git.gnome.org/cgit/gjs/tree/gi/object.c#n709 Is Gjs correct and we can do something generically and drop pygobject_register_sinkfunc? You can track my work here: http://git.sugarlabs.org/projects/pybank/repos/mainline And learn more about pybank here: http://live.gnome.org/PyBank/ Thanks, Tomeu ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

[pygtk] Spead Sheet like widget
Hi Need to edit some tables, mostly smaller but some up to 2000 rows, 16-30ish columns. Some spread sheet like calculations, but nothing to complex. What are the best suggestions, the app needs to run on Win32 as well as Linux.

[pygtk] Extract GtkObject from PyObject
Hi, I'm trying to embed python in my c-application so that I can use matplotlib. My python code sets up a GtkObject to sends signals. I want to pass a reference to this GtkObject back to my C-Code so that I can then send signals from C. I can use SWIG to create C functions that are callable from python. In this case I pass a Python GtkObject (PyGtkObject) into my C-function. From this PyObject I need to extract a GtkObject so that I can use it with the gtk functions in C. Can anyone help me do this? I assume PyGtk does this in order to interface with the C language bindings for gtk.

[pygtk] building pygobject on windows
Hi, I'm trying to find some information about the best way to build pygobject on Windows. Is there a preferred method to do this? I'd prefer to use whatever method is employed for the binaries that are supplied for download on pygtk.org, as I've tested those and they work fine for me, except for this bug: http://bugzilla.gnome.org/show_bug.cgi?id=546802 which I've been running into. The patch fixes my problems in Linux, so I'd like to build pygobject 2.14.2 for Windows with that patch applied, if possible. thanks, dave ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
