I will try to implement this soon.

I confirm this is working.

I tried with both Python 2.7 and Python 3.7.2. I did not have any problems moving widgets around. I think these crashes should be investigated more before adding any deactivation code. I am using wxPython 4.0.3 so that could be a reason why I don't see the crashes.

Ok. I will try to do this.

Slots still do make sense for the grid-based sizers. 

Thank you.
