[vtkusers] Latest nightly build: QT

[Doug Hoppes]

Oh.. that's quite possible.  I thought that I included all of the files that were in the Install directory, but may not have.

Please keep on list...

If is difficult, but not impossible, to build VTK apps without CMake.

VTK6 has over 100 libraries. I suspect you are missing vtkRendering/OpenGL needed for VTK6's factory mechanism.

Yes, this is an app that I'm building outside of VTK.  It's a QT application built with Visual studio 2008.  I'm not using a CmakeList.txt file.

Is this an application you are building outside of VTK? If so, can you share your CMakeLists.txt file?

Hi all,

                Okay, got the latest nightly build and trying out the QT implementation (there's a bug fix with destructor order in QT that I need).    With the latest change (vtkTDxConfigure.h being copied), I can get the code to compile.  However, running into a new issue: The renderwindow isn't built.

                My code (I have a class called VTKView which is subclassed from QVTKWidget). In my QT window, I have placed a QWidget and promoted it to VTKView.

VTKView::VTKView(QWidget *pParent)
:QVTKWidget(pParent), m_pUIProcessor(NULL), m_pSolidsImage(NULL)
{
            m_pUIProcessor = new VTKSceneManager(GetRenderWindow());
}

In QVTKWidget, it calls the function:
vtkRenderWindow* QVTKWidget::GetRenderWindow()
{
      if (!this->mRenWin)
      {
      // create a default vtk window
      vtkRenderWindow* win = vtkRenderWindow::New();
      this->SetRenderWindow(win);
      win->Delete();
      }
      return this->mRenWin;
}

                However, the software crashes because the variable "win" is null, after calling the vtkRenderWindow::New().

Also, as a side note, I had to comment out a lot of function calls (should I not be using these any more?):
                'SetScalarTypeToUnsignedChar' : is not a member of 'vtkImageData'
'vtkImageData::SetNumberOfScalarComponents' : function does not take 1 arguments
'vtkImageData::AllocateScalars' : no overloaded function takes 0 arguments
'SetInput' : is not a member of 'vtkImageShiftScale'
'SetInput' : is not a member of 'vtkImageActor'
'SetInput' : is not a member of 'vtkOutlineFilter'
'SetInput' : is not a member of 'vtkPolyDataMapper'
'SetInput' : is not a member of 'vtkSmartVolumeMapper'
