Came for the beer, stayed for the Freedom

I just put together a neat little decorator to force a method to be called via the default gobject main loop. It does this by wrapping a method call via an immediate timeout of the main loop.

def callFromMain(f):
    import gobject
    def dispatch(items):
        args, kwargs = items
        return f(*args, **kwargs)
    def wrapper(*args, **kwargs):
        gobject.timeout_add(0, dispatch, (args, kwargs))
    return wrapper
 

This works well for callbacks that come from other threads.

@callFromMain
def resultCallback(*args):
    print args
