[Paraview-developers] How to write to the output window?

[Biddiscombe, John A.]

One method I use (on windows) is to add this to the main application

int main(int argc, char* argv[])

{

#ifdef WIN32

AllocConsole();

freopen("conin$", "r", stdin);

freopen("conout$", "w", stdout);

freopen("conout$", "w", stderr);

#endif



and then you can use std::cout to write to a terminal window.

Note that the paraview main is generated from an *.in file so it's better to modify the *.in file which generates paraview_main.cxx

Try using the vtkErrorMacro() or vtkWarningMacro() ( or use qWarning(), qCritical(), qDebug() in Qt code)
