wxWidgets had been started long before the exceptions were introduced in C++ so
it is not very surprizing that it is not built around using them as some more
modern C++ libraries are. For instance, the library doesn't throw exceptions to
signal about the errors. Moreover, up to (and including) the version 2.4 of
wxWindows, even using the exceptions in the user code was dangerous because the
wxWidgets, even using the exceptions in the user code was dangerous because the
library code wasn't exception-safe and so an exception propagating through it
could result in memory and/or resource leaks, and also not very convenient.

Starting from the version 2.5.1 wxWidgets becomes more exception-friendly. It
still doesn't use the exceptions by itself but it should be now safe to use the
exceptions in the user code and the library tries to help you with this. Please
note that making the library exception-safe is still work in progress.

There are several choice for using the exceptions in wxWidgets programs. First
of all, you may not use them at all. As stated above, the library doesn't throw
any exceptions by itself and so you don't have to worry about exceptions at all
unless your own code throws them. This is, of course, the simplest solution but
