Bug summary
When using clear figure, adding new widgets and then redrawing the current figure in the on_changed callback of a range slider the inputs to all the widgets in the figure are blocked. When doing the same in the button callback on_clicked, everything works fine.
Code for reproduction
import matplotlib.pyplot as pyplot
import matplotlib.widgets as widgets
def onchanged(values):
print("on changed")
print(values)
pyplot.clf()
addElements()
pyplot.draw()
def onclick(e):
print("on click")
pyplot.clf()
addElements()
pyplot.draw()
def addElements():
ax = pyplot.axes([0.1, 0.45, 0.8, 0.1])
global slider
slider = widgets.RangeSlider(ax, "Test", valmin=1, valmax=10, valinit=(1, 10))
slider.on_changed(onchanged)
ax = pyplot.axes([0.1, 0.30, 0.8, 0.1])
global button
button = widgets.Button(ax, "Test")
button.on_clicked(onclick)
addElements()
pyplot.show()Actual outcome
The widgets can't receive any input from a mouse click, when redrawing in the on_changed callback of a range Slider.
When using a button, there is no problem.
Expected outcome
The range slider callback on_changed behaves the same as the button callback on_clicked.
