[vtkusers] GUISupport python wrappers?

[Michka Popoff]

Hi

FYI if you use QVTKRenderWindowInteractor, I wrote some examples how to embed vtk in a PyQt app (with the help of some people here on the list).
In the first example you have also some explanations on why the code has to be written like this.

http://www.vtk.org/Wiki/VTK/Examples/Python/Widgets/EmbedPyQt
http://www.vtk.org/Wiki/VTK/Examples/Python/Widgets/EmbedPyQt2

This could help you for PySide if you try to embed VTK.
I would be glad to have some input from you to know if this works as nicely with PySide as with PyQt (I can then update the wiki telling people it’s also working / or not working with PySide).


Some more thoughts about the QVTKWidgets : The following part applies only to VTK 5.10.1, I did not test it with VTK 6, and as David Gobbi said these options seem to be gone in VTK 6 :
You can check out this discussion I had on the bug tracker about the QVTKWidgets (1 and 2). Look at the very end of the discussion
http://vtk.org/Bug/view.php?id=13983
In cmake, use VTK_USE_QVTK_QTOPENGL:BOOL=ON, to have QVTKWidget2 in python
With VTK_WRAP_PYTHON_SIP I think you will get only the QVTKWidget (1).
