Re: [orca-list] time...

Hi Daniel:

See 
http://www.pygtk.org/pygtk2reference/gobject-functions.html#function-gobject--timeout-add

The basic pattern is this:

1) add the timeout (in milliseconds):

    gobject.timeout_add(1000, myMethod)

2) write your method:

    def myMethod():
        <<<output braille>>>
        return True

With the example above, myMethod will be called once a second.  No need 
to do a loop in myMethod since the timeout is basically doing the timed 
loop for you.
