FileOutputWindow
VTKExamples/Cxx/Utilities/FileOutputWindow
Description¶
This example shows how to pipe error output to a text file instead of the usual vtk pop-up window.
Code¶
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) target_link_libraries(FileOutputWindow ${VTK_LIBRARIES})
Download and Build FileOutputWindow¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
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.
