One thing I see off the bat is your addmpl() method:
```
def addmpl(self, fig):
#FigureCanvas.__init__(self, fig)
self.canvas = FigureCanvas(fig)
Axes3D.mouse_init(self, rotate_btn=1, zoom_btn=2)
self.mplvl.addWidget(self.canvas)
self.canvas.draw()
self.toolbar = NavigationToolbar(self.canvas, self.mplwindow,
coordinates=True)
self.mplvl.addWidget(self.toolbar)
```
You are calling Axes3D.mouse_init() on the Main object (that is `self`).
That is completely wrong. It can only be called for the 3d axes objects.
Also, what I see happening here is some mixing up of how to do embedding.
There are two approaches to embedding. 1) you can embedded GUI elements
into your canvas widget, or 2) you can embed your canvas widget into your
GUI app. The important distinction between the two is who controls the
mainloop. In option 1 (and in matplotlib in general), pyplot will create
the GUI app for you automatically (it is completely transparent to you) and
kicks it off upon call to show(). But option 2 relinquishes that control to
the developer's GUI app. You *cannot* use pyplot for option 2, which is
what you are doing. Rip out all of the pyplot stuff, and instantiate the
Qt5 Figure object directly, and then obtain the axes objects from the
figure object via calls to add_subplot(). You shouldn't even need to do the
whole mouse_init() stuff.
I now think this has nothing to do with Qt Designer. While I don't
specifically cover qt5 in my book, I do make all of these distinctions very
clear in chapter 5 of my book "Interactive Applications using Matplotlib".
Cheers!
