This example shows how to pipe error output to a text file instead of the usual vtk pop-up window.

FileOutputWindow.cxx

#include <vtkFileOutputWindow.h>
#include <vtkXMLPolyDataReader.h>
#include <vtkSmartPointer.h>
 
int main(int, char *[])
{
  vtkSmartPointer<vtkFileOutputWindow> fileOutputWindow = 
      vtkSmartPointer<vtkFileOutputWindow>::New();
  fileOutputWindow->SetFileName( "output.txt" );
 
  // Note that the SetInstance function is a static member of vtkOutputWindow.
  vtkOutputWindow::SetInstance(fileOutputWindow);
 
  // This causes an error intentionally (file name not specified) - this error will be written to the file output.txt
  vtkSmartPointer<vtkXMLPolyDataReader> reader = 
      vtkSmartPointer<vtkXMLPolyDataReader>::New();
  reader->Update();
 
  return EXIT_SUCCESS;
}

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
 
PROJECT(FileOutputWindow)
 
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
 
add_executable(FileOutputWindow MACOSX_BUNDLE FileOutputWindow.cxx)

Download and Build FileOutputWindow

Click here to download FileOutputWindow. and its CMakeLists.txt file.

Once the tarball FileOutputWindow.tar has been downloaded and extracted,

cd FileOutputWindow/build 
  • If VTK is installed:
cmake ..
  • If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

make

and run it:

./FileOutputWindow

WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
