matplotlib.widgets.AxesWidget#

classmatplotlib.widgets.AxesWidget(ax)[source]#

Bases:Widget

Widget connected to a singleAxes.

To guarantee that the widget remains responsive and not garbage-collected,a reference to the object should be maintained by the user.

This is necessary because the callback registrymaintains only weak-refs to the functions, which are memberfunctions of the widget. If there are no references to the widgetobject it may be garbage collected which will disconnect the callbacks.

Attributes:

axAxes

The parent Axes for the widget.

canvasFigureCanvasBase

The parent figure canvas for the widget.

activebool

Is the widget active?

propertycanvas#

connect_event(event,callback)[source]#

disconnect_events()[source]#

Disconnect all events created by this widget.

ignore(event)[source]#

Return whetherevent should be ignored.

This method should be called at the beginning of any event callback.
