// .NAME vtkOutputWindow - base class for writing debug output to a console
|
|
// .SECTION Description
|
|
// This class is used to encapsulate all text output, so that it will work
|
|
// with operating systems that have a stdout and stderr, and ones that
|
|
// do not. (i.e windows does not). Sub-classes can be provided which can
|
|
// redirect the output to a window.
