Integrating VTK with PyQT

Support
1

Hi. I am using vtk in my pyQt project.
The issue I’m encountering is puzzling because the error doesn’t occur every time. Do you have any ideas on what might be causing this and how to diagnose it?

Here is the relevant code snippet of the creation of my viewer:

class myViewer(QVTKRenderWindowInteractor):
        def __init__(self, parent=None):
        super().__init__(parent) 
        self.Init_view()


    def Init_view(self):
        self.Initialize()
        self.Start()
        self.renderer = vtkRenderer()
        self.GetRenderWindow().AddRenderer(self.renderer)

        self.interactor = self.GetRenderWindow().GetInteractor()
        self.interactor.SetInteractorStyle(self.style_2d) 
                 
        self.renderer.ResetCamera()
        self.show()

The following is the results in the terminal:

  File "C:\Users\.conda\envs\vtkenv\lib\site-packages\vtkmodules\qt\QVTKRenderWindowInteractor.py", line 473, in 
resizeEvent
    self._Iren.SetSize(w, h)

    elif hasattr(self._Iren, attr):

    elif hasattr(self._Iren, attr):

    elif hasattr(self._Iren, attr):

    if attr == '__vtk__':

Thanks in advance for your help! :blush:
