Bug 547633 – cannot create new threads when pygtk is used
2008-08-28 Paul Pogonyshev <pogonyshev@gmx.net>
Bug 547633 – cannot create new threads when pygtk is used
* glib/pyglib.c (pyglib_notify_on_enabling_threads): New function.
(pyglib_enable_threads): Invoke all callbacks added with new
pyglib_notify_on_enabling_threads().
* gobject/gobjectmodule.c (pyg_note_threads_enabled): New
function (callback for new pyglib_notify_on_enabling_threads()).
(PYGLIB_MODULE_START): Initialize
'pygobject_api_functions.threads_enabled' and also watch for
thread being enabled later on.
