[vtkusers] Problem with Volume rendering inside Qt application. ​​

[Kim Rosenbohm]

 Hi.

I use QVTKWdget2, but in QVTKWidget you should be able to call
"update()" to update the Qt widget / view too...

Best Regards,

Kim

need to do while creating the pipeline is to not provide the data to the
mapper. Once you load the file/data, you can set that as the input data
to the mapper and call Render on the RenderWindow.

rendering volume in my VTK+ITK+Qt application, which should visualize
DICOM volumetric data in QVTKWidget. But when I create my volume
pipeline firstly (as a non-part of Qt mechanism), and than setup Qt ui
and run RenWin->Render() everything works fine. Unfortunatelly, I want
to setup ui first, let the user choose the file to load and than render
volume. Is it some kind of known issue? I work on Ubuntu 12.04 + VTK 5.8
+ ITK 4.5.
