matplotlib.widgets.LockDraw#
- class matplotlib.widgets.LockDraw[source]#
Some widgets, like the cursor, draw onto the canvas, and this is not desirable under all circumstances, like when the toolbar is in zoom-to-rect mode and drawing a rectangle. To avoid this, a widget can acquire a canvas' lock with
canvas.widgetlock(widget)before drawing on the canvas; this will prevent other widgets from doing so at the same time (if they also try to acquire the lock first).Methods
