`vtkOutputWindow` is used to print error/warning information.
For example:
Is there any method to keep the printed information but do not show the `vtkOutputWindow`?
I have tested `vtkOutputWindow::SetGlobalWarningDispaly(0)` can forbid the `vtkOutputWindow`, but it also don’t show the printed information in console.
How to output error/warning information to console but hide the `vtkOutputWindow`?

Are you setting a factory to use the vtkWin32OutputWindow ? A standard vtkOutputWindow does not show the window afaik.

No, I have no setting about output window. But the `vtkOutputWindow` appears when a error/warning is reported.
Now, I need the printed information, but I don’t want `vtkOutputWindow`.

You want to override with your own factory then.

Why print the error/warning information to console, but also show it in `vtkOutputWindow`?
Why don’t show the error/warning information in console **or** `vtkOutputWindow`?
It is unnecessary to show the information twice.

I agree, please improve the vtkWin32OutputWindow to support all this, thanks 🙂

I’m a Unix guy, but I would be surprised to find that windows didn’t have some way of redirecting standard error output to somewhere else. I haven’t tested this (I’m a Unix guy), but [this website](https://www.rushis.com/windows-command-prompt-redirecting-stdoutstderr/) seemed to think that it was possible to do these redirects in a Unix-y fashion on windows!
