\section{wxUSE Preprocessor symbols defined by wxWidgets}\label{wxusedef}

This section documents the wxUSE preprocessor symbols used in the wxWidgets
source, grouped by category (and sorted by alphabetical order inside each
category). These symbols are always defined and whether the given feature is
active or not depends on their value: if defined as $1$, feature is active,
otherwise it is disabled. Because of this these symbols should be always tested
using \texttt{#if} and not \texttt{#ifdef}.
