[vtkusers] creating a VTk in MFC

[Asad A. Abu-Tarif]

Hi Giancarlo,
You do everything normally except you call
SetParentId(m_hWnd);
of the rendering window instance.

For the more advanced stuf, you can be
as creative as you want. I personally put
the vtk code in a class derived from the
MFC CView class. I trap the screen size
change inside the main CView class and
resize the rendering window accordingly.

Below you can find pieces of code form
my main application. They should be easy
to follow. I use the single-document-single-view
architecture.

Good luck.
Asad

 GetDocument()->renWin = vtkRenderWindow::New();
 GetDocument()->renWin->AddRenderer(GetDocument()->renderer1);
 GetDocument()->renWin->SetParentId(m_hWnd);

 GetDocument()->iren->SetRenderWindow(GetDocument()->renWin);
