I would look at line 24/25. You are constructing a MyStaticMplCanvas
instance on 24, with a self.main_widget as the parent. But then on 25, you
explicitly call the constructor again (which is not a good idea), but with
the main window as the parent (the self argument). I bet that is throwing
off a couple things.
The code is extremely hard to follow, and I think it is a bad example to
build off of in the first place (unnescessary subclassing). Perhaps a
different example would be more suitable? What programming language are you
coming from?
