Hello all,<br><br>I want to create a GUI using PyQt4 and display a vtkImage inside it. For that, I need to embed a QVTKWidget in my GUI. However, I get 'ImportError: No module named qvtk' when I do import vtk.qvtk as given in <a href="http://vtk.1045678.n5.nabble.com/about-vtk-python-bindings-and-Qt-td2841114i20.html" target="_blank">http://vtk.1045678.n5.nabble.com/about-vtk-python-bindings-and-Qt-td2841114i20.html</a> . I am confused about how to get started with this and did not find examples demonstrating this. <br>
<div><br></div><div>Please point me to the steps for writing this "hello world".</div><div><br></div><div>Thanks,</div><div>Prathamesh</div></div>
