Re: [Matplotlib-users] Axes3d.mouse_init(), facing problems when embedding matplotlib 3d-projection into PyQt5 App

[Christian A. <am...@ym...>]

 Since there seems to be no progress with this issue, may I assume there isn't any interest in it?I took a further look around in the internet but couldn't any solution.It leads to an other question: How many users of matplotlib are using 3d-plots anyway? It we are just a few and there won't be anyone who wants to embed it in PyQt5, than I can understand that this issue doesn't concern no-one and I have to look somewhere else to find a 3d-plotting lib which is embedable.
cheers,Christain

 The addmpl() method isn't right. You created a canvas object, assigned it to self.canvas, but then tried to call FigureCanvas.__init__(), passing it whatever object "self" is. What class is addmpl() a part of? What does it subclass?

Hi,
I embedded Ryan's examble for PyQt5-matplotlib use into my App but I get the following error:
/usr/local/lib/python3.4/dist-packages/mpl_toolkits/mplot3d/axes3d.py:1009: UserWarning: Axes3D.figure.canvas is 'None', mouse rotation disabled.  Set canvas then call Axes3D.mouse_init().
  warnings.warn('Axes3D.figure.canvas is \'None\', mouse rotation disabled.  Set canvas then call Axes3D.mouse_init().')

>From Stackoverflow, which host to question about this, I know that mouse actions are disabled when the canvas is re-initialized by whatever.
The only position I do such an operation is in here:    def addmpl(self, fig):
        self.canvas = FigureCanvas(fig)
        #FigureCanvas.__init__(self, fig)
        #Axes3D.mouse_init(self)
        self.mplvl.addWidget(self.canvas)
        self.canvas.draw()
        self.toolbar = NavigationToolbar(self.canvas, self.mplwindow, coordinates=True)
        self.mplvl.addWidget(self.toolbar)
 On of the Stackoverflow suggestion says, that re initializing FigureCanvas should do the trick but I'll get: 

Traceback (most recent call last):
  File "./ex_0.1.py", line 145, in <module>
    main(sys.argv)
  File "./ex_0.1.py", line 53, in main
    mainwindow.addmpl(fig1)
  File "./ex_0.1.py", line 116, in addmpl
    FigureCanvas.__init__(self, fig)
  File "/usr/local/lib/python3.4/dist-packages/matplotlib/backends/backend_qt5agg.py", line 181, in __init__
    FigureCanvasQT.__init__(self, figure)
  File "/usr/local/lib/python3.4/dist-packages/matplotlib/backends/backend_qt5.py", line 237, in __init__
    super(FigureCanvasQT, self).__init__(figure=figure)
TypeError: super(type, obj): obj must be an instance or subtype of type

as follow-up error message.
just using Axes3D.mouse_init() , as suggested by matplotlib itself, leads to:
Traceback (most recent call last):
  File "./ex_0.1.py", line 146, in <module>
    main(sys.argv)
  File "./ex_0.1.py", line 53, in main
    mainwindow.addmpl(fig1)
  File "./ex_0.1.py", line 118, in addmpl
    Axes3D.mouse_init()
TypeError: mouse_init() missing 1 required positional argument: 'self'
adding self leads to:
Traceback (most recent call last):
  File "./ex_0.1.py", line 146, in <module>
    main(sys.argv)
  File "./ex_0.1.py", line 53, in main
    mainwindow.addmpl(fig1)
  File "./ex_0.1.py", line 118, in addmpl
    Axes3D.mouse_init(self)
  File "/usr/local/lib/python3.4/dist-packages/mpl_toolkits/mplot3d/axes3d.py", line 1002, in mouse_init
    canv = self.figure.canvas
AttributeError: 'Main' object has no attribute 'figure'
./ex_0.1.py &

Maybe I'm adding those lines at the wrong place, but I could fined anything useful in the matplotlib documantation, that would help me out, either.
Any thougts that might help?
Cheers,Christian
