[vtkusers] Re: vtkImagePlaneWidget problem on vtkImageData (C++)

[Adrian Wyssmann]

Ok, I have to add something like this:  
myImageViewer2->SetParentId(m_hWndData);

But now I have the next problem: If I do a right-click on the imageViewer,  
the image change to grayscale. Where have the corlors gone?

Thanks for helping me.

Adrian
