Benjamin, I am using this to show the upload-progress of a 4 GB file, using gtk.ProgressBar(). The file takes about 15 minutes to upload, and I only see the progress bar (fraction = 1) right at the end; which means that only after the uploading is done, and there is nothing else to be done, does the GUI update takes place. Also, I was just going through <a href="http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html#g-idle-add" target="_blank">http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html</a> There I observed, that by using the combination of :: <a href="http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html#g-idle-source-new" target="_blank">http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html#g-idle-source-new</a> <a href="http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html#g-source-attach" target="_blank">http://developer.gnome.org/glib/2.30/glib-The-Main-Event-Loop.html#g-source-attach</a> we could solve our purpose, since the "g-source-attach"<var></var><code></code><var></var><code></code><var></var><var></var><code></code> can be done in a different context, whose mainloop would be running in a different thread. But I did not find the corresponding methods for Python. Am I missing something?
