no, this is not supported and will most likely break.
when you want to update the UI inside the thread that did not call
clutter_main() you should install an idle handler with:
clutter_threads_add_idle (idle_ui_update, NULL):
and declare idle_ui_update() as:
static gboolean
idle_ui_update (gpointer data)
{
/* from here it's safe to update the UI */
}
the idle handler is guaranteed to be invoked from the same thread that
has called clutter_main() - and this is the only portable and reliable
way to use Clutter with multiple threads.
you should have a look at the test-threads.c test case shipped in the
Clutter tarball, inside the tests/ directory.
