This provides several classes used for blocking interaction with figure windows:

:class:`BlockingInput`
    creates a callable object to retrieve events in a blocking way for interactive sessions

:class:`BlockingKeyMouseInput`
    creates a callable object to retrieve key or mouse clicks in a blocking way for interactive sessions.
    Note: Subclass of BlockingInput. Used by waitforbuttonpress

:class:`BlockingMouseInput`
    creates a callable object to retrieve mouse clicks in a blocking way for interactive sessions.
    Note: Subclass of BlockingInput.  Used by ginput

:class:`BlockingContourLabeler`
    creates a callable object to retrieve mouse clicks in a blocking way that will then be used to place labels on a ContourSet
    Note: Subclass of BlockingMouseInput.  Used by clabel

        This removes an event from the event list.  Defaults to
        removing last event, but an index can be supplied.  Note that
        this does not check that there are events, much like the
        normal pop method.  If not events exist, this will throw an

    Class that creates a callable object to retrieve mouse clicks in a
    blocking way.

    This class will also retrieve keyboard clicks and treat them like
    appropriate mouse clicks (delete and backspace are like mouse button 3,
    enter is like mouse button 2 and all others are like mouse button 1).

        This will be called if button 3 is clicked.  This will remove
        a label if not in inline mode.  Unfortunately, if one is doing
        inline labels, then there is currently no way to fix the
        broken contour - once humpty-dumpty is broken, he can't be put
        back together.  In inline mode, this does nothing.
