Base class of the other classes listed here. `BlockingKeyMouseInput` Creates a callable object to retrieve key or mouse clicks in a blocking way for interactive sessions. Used by `~.Figure.waitforbuttonpress`. `BlockingMouseInput` Creates a callable object to retrieve mouse clicks in a blocking way for interactive sessions. Used by `~.Figure.ginput`. `BlockingContourLabeler` Creates a callable object to retrieve mouse clicks in a blocking way that will then be used to place labels on a `.ContourSet`. Used by `~.Axes.clabel`.
