[pygtk] gobject.idle_add and generators

[Aravind Vijayakumar]

I think you'll have to call it like this:

iter = g()
gobject.idle_add(iter.next)

And yes, to terminate the idle execution, you would yield False.

Sorry, kind of new to the idea of using simple generators in place of
regular functions, but I think I have the classic "need to save intermediate
state" case which would make it worthwhile.  The current function-based
approach I'm using is pretty cumbersome.  Suppose g is a simple generator:

    def g():
        while True:
            do_something_useful()
            yield True

Does it make sense to call it like this?

    gobject.idle_add(g)

If I want to terminate the idle execution I suppose I'd have to arrange to
yield False instead of True, just as with a regular function, yes?

Thx,
