This is a general overview of logging classes provided by wxWidgets. The word
logging here has a broad sense, including all of the program output, not only
non interactive messages. The logging facilities included in wxWindows provide
non interactive messages. The logging facilities included in wxWidgets provide
the base {\it wxLog} class which defines the standard interface for a {\it log

functions to use with them.

The usage of these functions should be fairly straightforward, however it may
be asked why not use the other logging facilities, such as C standard stdio
functions or C++ streams. The short answer is that they're all very good
generic mechanisms, but are not really adapted for wxWindows, while the log
classes are. Some of advantages in using wxWindows log functions are:

\item{\bf Completeness} Usually, an error message should be presented to the user

error: suppose that you're writing your data file on disk and there is not
enough space. The actual error might have been detected inside wxWindows code

(say, in {\it wxFile::Write}), so the calling function doesn't really know the
exact reason of the failure, it only knows that the data file couldn't be
written to the disk. However, as wxWindows uses {\it wxLogError()} in this
