[vtkusers] Vtk Python Widgets

[CHENET Aude (External)]

Hello,

I’ve built VTK from sources with Tk Components. I can find in my path D:\VTK\bin\vtkRenderingPythonTkWidgets-6.3.dll
I don’t have any more the error I had before. But when I run OrthogonalPlanesWithTkPhoto.py it stops without reason.
I tried to debug, and find the problem is in vtkLoadPythonTkWidgets.py, at the end of the script. It tries to load the dll (and it doesn’t work?) and the program is terminated with exit value -1073741819…

Does someone have an idea?

Yes.  As far as I understand, that is the situation.

Thanks for your answer.
It means it is not possible to get vtk with pip ? It’s mandatory to build vtk from sources to have acces to TkWidgets?

Hi Aude,

This means that your vtk package was built without the Tk components.
I don't know of any binary packages that provide the DLL that you need,
you might have to build your own vtk with VTK_Group_Tk:BOOL=ON.

Hello,

I’m trying to use vtk with Python 27. I’ve installed vtk 6.2 with pip.
When I execute OrthogonalPlanesWithTkPhoto.py example, I’ve an error :
Traceback (most recent call last):
  File "C:\Users\chenet-
ext\workspace\OCT\src\OrthogonalPlanesWithTkPhoto.py", line 156, in

line 81, in vtkLoadPythonTkWidgets
    interp.call('load', filename, pkgname)
_tkinter.TclError: couldn't load library "vtkRenderingPythonTkWidgets-
6.2.dll": this library or a dependent library could not be found in
library path

I’ve made a research on my computer and I can’t find
vtkRenderingPythonTkWidgets.
Can someone help me to use this example?
