Problem Description

when using ipwidgets to create interactive script, the plots cannot be updated using widgets when console is activated, and this problem can be solved if I close the notebook console. However, by doing so, I have no access to the variable explorer anymore.

What steps reproduce the problem?

1. import numpy and ipwidgets library
2. load 2d array, then using ipwidgets to create a slider to plot each row in the array
3. the plot will updated when moving the slider, but if I activated the console for variable explorer, the plot will not updated anymore.

What is the expected output? What do you see instead?

Hey @wangxinwei1017, thanks for reporting. I'm going to move your issue to the Spyder-notebook repo, which is where it really belongs.

I have the similar issue, but with buttons. It looks like events from the widgets are not processed if the console is opened.
