[vtk-developers] Linking a VTK viewer in MFC Application

[David Cole]

The sample in VTK/Examples/GUI/Win32/SampleMFC shows the following
code in vtkMFCRenderView.cpp:

int vtkMFCRenderView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  if (vtkMFCView::OnCreate(lpCreateStruct) == -1)
    return -1;

  // TODO: Add your specialized creation code here
  this->RenderWindow->SetParentId(lpCreateStruct->hwndParent);

  return 0;
}

This, and other code in that class, makes the VTK render window occupy
the client area of the MFC view. You have to put a parent window
around the VTK window in order to do what you want. And then deal with
making sure resizing, focus and keyboard events are properly handled.
It's not trivially easy, but it's do-able.


HTH,
David
