[vtkusers] Problem with getting mouse position.

[Łukasz Tutaj]

Hi Mark,

Thank you for your answer. I've tried to use vtkImageViewer2  and 
displaying works quite good  (there is some error after quitting the 
program)  in wingdi.cpp file

CPaintDC::~CPaintDC()
{
   ASSERT(m_hDC != NULL);
   ASSERT(::IsWindow(m_hWnd));      // Error in this place

   ::EndPaint(m_hWnd, &m_ps);
   Detach();
}

However I still don't know how to get mouse position. I want to 
emphasise that I use MFC to provide GUI.
Maybe you can sent me some code to explain me how to get mouse position.
