wxWidgets had been started long before the exceptions were introduced in C++ so

+it is not very surprising 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
wxWidgets, even using the exceptions in the user code was dangerous because the
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
all the exceptions thrown by any event handler.

To use any kind of exception support in the library you need to build it with
\texttt{wxUSE\_EXCEPTIONS} set to $1$. This should be the case by default but
