        :param wait_for_not: The state to wait for the window to not be in. It can be any
            of the following states, also you may combine the states by space key.

             * 'exists' means that the window is a valid handle
             * 'visible' means that the window is not hidden
             * 'enabled' means that the window is not disabled
             * 'ready' means that the window is visible and enabled
             * 'active' means that the window is active

        :param timeout: Raise an :func:`pywinauto.timings.TimeoutError` if the window is sill in the
            state after this number of seconds.
            Default: :py:attr:`pywinauto.timings.Timings.window_find_timeout`.

        :param retry_interval: How long to sleep between each retry.
            Default: :py:attr:`pywinauto.timings.Timings.window_find_retry`.

        An example to wait until the dialog is not ready, enabled or visible: ::

            self.Dlg.wait_not("enabled visible ready")
