[vtk-developers] Re: GUISupport directory ?

[de Boer Ingo]

Hi,

Mathieu asked me to join in this conversation.

First of all, I have submitted some new MFC samples in the
bug tracker some time ago. You can find them at:

http://www.vtk.org/Bug/bug.php?op=show&bugid=649&pos=0

Now, when you want to use a CWnd with VTK you have to
handle some CWnd functions, like (pseudo code):

OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 this->pvtkWin32OpenGLRW->AddRenderer(this->pvtkRenderer);
 this->pvtkWin32OpenGLRW->SetParentId(this->GetParent()->GetSafeHwnd());
 this->pvtkWin32OpenGLRW->SetWindowId(this->GetSafeHwnd());
 this->pvtkWin32RenderWI->SetRenderWindow(this->pvtkWin32OpenGLRW);
 if ( !this->pvtkWin32RenderWI->GetInitialized() )
  this->pvtkWin32RenderWI->Initialize();
}
OnSize(UINT nType, int cx, int cy)
{
 CRect cRect;
 this->GetWindowRect(cRect);
 if (this->pvtkWin32RenderWI->GetInitialized())
  this->pvtkWin32RenderWI->UpdateSize(cRect.Width(), cRect.Height());
}
WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
 switch (message)
 {
  case WM_LBUTTONDOWN: 
  case WM_LBUTTONUP: 
  case WM_MBUTTONDOWN: 
  case WM_MBUTTONUP: 
  case WM_RBUTTONDOWN: 
  case WM_RBUTTONUP: 
  case WM_MOUSEMOVE:
  case WM_CHAR:
  case WM_TIMER:
   if (this->pvtkWin32RenderWI->GetInitialized())
   {
     return vtkHandleMessage2(this->GetSafeHwnd(), message, wParam, lParam, this->pvtkWin32RenderWI);
   }
  break;
  }
}
OnEraseBkgnd(CDC* pDC)
{
  return TRUE;
}

The more detailed version can be found in the view classes of the samples.

greets
  Ingo
