gobject io monitoring + nonblocking reads
I've got a problem with using the io_add_watch monitor in python (via gobject). I want to do a nonblocking read of the whole buffer after every notification. Here's the code (shortened a bit): class SomeApp(object): def __init__(self): # some other init that does a lot of stderr debug writes fl = fcntl.fcntl(0, fcntl.F_G...
In Gobject, how to overrid parent class's method belong to an interface?
Gojbect class A implements interface IA, B is subclass of A. How can B override A's method that is part of the interface? Or, is this possible for gobject? I know how to override parent class method, but when inheritance meets interface, things seems to be more complicated. Thanks a lot! ...

Strangest Error I Have Ever Seen, a.k.a. ) *
I'm writing this awesome application, at least I think it awesome, in C with the magnificent blend of GObject and after a while I start getting this very, extremely strange error. I also believe to have noticed it not appearing always. However this might just be the IDE's fault. Anyhow... GCC, apparently, complains: expected ')' before ...

pydev issue with gobject
It seems that Pydev (1.5.4) on Eclipse (3.5.1) with Python 2.6 isn't able to correctly cross-reference the package gobject. Putting import gobject works OK but any more than that (e.g. class X(gobject.GObject) causes Pydev to report "unresolved reference" errors. What could be the problem? Note that every other package I use doesn't t...
What does g_signal_connect_swapped() do?
According to GObject reference g_signal_connect_swapped(instance, detailed_signal, c_handler, data); connects a GCallback function to a signal for a particular object. The instance on which the signal is emitted and data will be swapped when calling the handler. I don't quite get what this means. Does this mean that the data will ...
How can I link to my own verson of GLib rather than the system installed one?
I have been looking through the source of GLib and GObject and writing programs to use certain features of each. But now I'd like to debug though something in the GLib source code without installing anything on my system. I have a built version of the source code somewhere and I'd like to use those .so files rather than the system inst...
Is there an alternative to gobject.timeout_add() in Python?
Hi there, I'm using gobject.timeout_add() to display a timer in my project (dojotools). I was wondering if there is any other way to achieve the same results, but without the gobject dependency. The requirement is just calling a method repeatedly, in a certain time interval. ...
Should a g_object_new have a matching g_object_unref?
I'm using libnotify to show desktop notifications in my application; notify_notification_new() returns a NotifyNotification*, which should be passed as the first param to further function calls of the notification library. There is no notify_notification_free() which frees the pointer it returns. I looked up the source of notify_notifi...
Up To Date Documentation on Wrapping gobjects with Python
I'm looking for up-to-date documentation and tutorials on creating Python bindings for gobjects. Everything I can find on the web is either incomplete or out of date. ...
Is there a good way to copy a Gtk widget?
Is there a way, using the Gtk library in C, to clone a Gtk button (for instance), and pack it somewhere else in the app. I know you can't pack the same widget twice. And that this code obviously wouldn't work, but shows what happens when I attempt a shallow copy of the button: GtkButton *a = g_object_new(GTK_TYPE_BUTTON, "label", "o_0",...
Python bindings for a vala library
I am trying to create python bindings to a vala library using the following IBM tutorial as a reference. My initial directory has the following two files: test.vala using GLib; namespace Test { public class Test : Object { public int sum(int x, int y) { return x + y; } } } test.override %% header...
Using enum properties in PyGTK/GObject
This tutorial on using GObject in Python only covers using a property of type gobject.TYPE_FLOAT. I've adapted it to use an enumerated type: import pygtk pygtk.require('2.0') import gobject FUEL_NONE = 0 FUEL_SOME = 1 FUEL_FULL = 2 class Car(gobject.GObject): __gproperties__ = { 'fuel' : (gobject.TYPE_ENUM, ...
Prevent propagation of GSignal to further registered GCallbacks
How to prevent further signal handlers to be called from the first signal handler callback in GSignal? For example, i register three functions - func1, func2 and func3 for the same signal "mysignal". If func1 is called first, how can i prevent func2 and func3 to be called from func1? This should not be made permanent. It should be runt...
Why does python gstreamer crash without "gobject.threads_init()" at the top of my script?
I have written a python script to use gstreamer (pygst and gst modules) to calculate replaygain tags, and it was crashing inconsistently with various gobject errors. I found somewhere that you could fix this by putting the following boilerplate at the top of your script: import gobject gobject.threads_init() I tried it, and it worked....
How are "out parameters" represented for Seed JavaScript GObject bindings?
I've just started using Seed for development. One thing that Seed's web page mentions is that it "Maps C-isms (say, out arguments, or enums) to things that make sense in JavaScript." Unfortunately, I can't find any documentation or examples for how out arguments should work. So, for example, the following call in Seed: window.get_size()...
