Solve the following python programming problem given the following code:
@ contextmanager 
def process_dialog(delay = 0, accept = False, reject = False, function = None) : 
    '
    Context manager to automatically capture the active dialog and carry out
    certain actions.

    Note that only one of ``accept``, ``reject``, or ``function`` should be
    specified.

    Parameters
    ----------
    delay : int, optional
        The delay in ms before acting on the dialog (since it may not yet exist
        when the context manager is called).
    accept : bool, optional
        If `True`, accept the dialog after the specified delay.
    reject : bool, optional
        If `False`, reject the dialog after the specified delay
    function : func, optional
        For more complex user actions, specify a function that takes the dialog
        as the first and only argument.
    ' 
    def _accept(dialog) : 
        dialog.accept () 
def _reject(dialog) : 
        dialog.reject () 
n_args = sum ((function, reject, (function is not None))) 
    if (n_args > 1) : 
        raise ValueError ('Only one of ``accept``, ``reject``, or ``function`` should be specified') 
else : 
        if (n_args == 0) : 
            raise ValueError ('One of ``accept``, ``reject``, or ``function`` should be specified') 
if accept : 
        function = _accept 
else : 
        if reject : 
            function = _reject 
def wrapper() : 
        from glue.external.qt import get_qapp 
        app = get_qapp () 
        dialog = app.focusWidget ().window () 
        function (dialog) 
timer = QtCore.QTimer () 
    timer.setInterval (delay) 
    timer.setSingleShot (True) 
    timer.timeout.connect (wrapper) 
    timer.start () 
    (yield)
