[vtkusers] problems with VTK and C++ Builder

[knut.bredemeier at technoteam.de]

Hello Radim,

I had the same problems. I ignored the warnings but the crash after programm - termination was not nice. I use the component BVTK to handle the vtk - view. In the destructor - code of this component I made some changes to solve this problem. I don't exactly know why, but it works:

New version:
------------
if(FInteractor)
{ FInteractor->Delete(); FInteractor = NULL; }
if(FRenderer) { FRenderer->SetRenderWindow(NULL); }
if(FRenderWindow) { FRenderWindow->Delete(); FRenderWindow = NULL; }
if(FRenderer) { FRenderer->Delete(); FRenderer = NULL; }

Old version:
------------
if (FInteractor) FInteractor->Delete();
if (FRenderer) { FRenderWindow->RemoveRenderer(FRenderer); FRenderer->Delete(); }
if (FRenderWindow) FRenderWindow->Delete();

Hi all,
could you please help me with this problem...

I've compiled (using Cmake) the VTK source for Borland Builder C++. I've created *.lib files and add to the project. 

Everything seems to be OK. But several problems arise:

- warning messages during compilation
      [C++ Warning] vtkDataArray.h(105): W8008 Condition is always false
      [C++ Warning] vtkDataArray.h(105): W8008 Condition is always false
      [C++ Warning] vtkFieldData.h(155): W8060 Possibly incorrect assignment
      [C++ Warning] vtkProperty.h(199): W8008 Condition is always false
      [C++ Warning] vtkProperty.h(199): W8008 Condition is always false
      [C++ Warning] vtkProperty2D.h(108): W8008 Condition is always false
      [C++ Warning] vtkProperty2D.h(108): W8008 Condition is always false
      [C++ Warning] vtkRenderWindow.h(326): W8008 Condition is always false
      [C++ Warning] vtkRenderWindow.h(326): W8008 Condition is always false
      [C++ Warning] vtkLocator.h(98): W8008 Condition is always false
      [C++ Warning] vtkLocator.h(98): W8008 Condition is always false
      [C++ Warning] vtkPointLocator.h(90): W8008 Condition is always false
      [C++ Warning] vtkPointLocator.h(90): W8008 Condition is always false
      [C++ Warning] vtkRenderWindowInteractor.h(257): W8008 Condition is always false
      [C++ Warning] vtkRenderWindowInteractor.h(257): W8008 Condition is always false
But I suppose it doesn't matter(?)

- After creating exe file, it asks for DLL file. Why? I use the LIB files (static library) during compilation and linking.

- And last and the worse error is, that after closing the interactive render window, I get error message:
"Access violation at adress 00c9c560" in module VTKRENDERING.DLL. Read of adrress 0260A8C6"

Well, I'm writing all these problems, because they could be connected...
Could you please help me?
Thanks, Radim
