[vtkusers] vtkImageViewer2 and QVTKWidget

[Marcos]

Hi Siavash,

thank you for responding, I appreciate it.

I added that line at the end, and I got a new window with the text:

ERROR: In C:\VTK-6.2.0\GUISupport\Qt\QVTKInteractor.cxx, line 147
QVTKInteractor (08ECEE60): QVTKInteractor cannot control the event loop.

On the other hand, I guess I know what the problem is. I didn't imagine it
could be that.

This code is inside a .cpp from a class named ViewerWidget. ViewerWidget is
a QWidget class, with an associated .ui file where I designed the widget:
just a QVTKWidget inside.

So in my MainWindow form (Qt Designer) I put that ViewerWidget.

>From this code, I could access my QVTKWidget, but maybe it's not correctly
initiated.

Why do I think this is the problem? Because I added a QVTKWidget to
MainWindow form, and passed a pointer to my ViewerWidget class. And the
image is loaded and I can see it.

I've spent a lot of time trying different codes (as I said, I saw a lot of
differents aproaches -renderers and interactors from one to another and
viceversa, classes like VTKImageExport, setting to vtkActor, etc-)

Maybe I shouldn't create the widget and just have the QVTKWidget where I
know it works, not inside another custom widget. I just wanted to
encapsulate things.

I'll leave the QVTKWidget in the MainWindow.

Thanks for your time.
