+\func{void}{OnFatalException}{\void}
+
+This function may be called if something fatal happens: an unhandled
+exception under Win32 or a a fatal signal under Unix, for example. However,
+this will not happen by default: you have to explicitly call
+\helpref{wxHandleFatalExceptions}{wxhandlefatalexceptions} to enable this.
+
+Generally speaking, this function should only show a message to the user and
+return. You may attempt to save unsaved data but this is not guaranteed to
+work and, in fact, probably won't.
