\subsection{Feature tests}\label{featuretests}
Some library features may not be always available even if they were selected by
the user. To make it possible to check if this is the case, the library
predefines the symbols in the form \texttt{wxHAS\_FEATURE}. Unlike
\texttt{wxUSE\_FEATURE} symbols which are defined by the library user (directly
in \texttt{setup.h} or by running configure script) and which must be always
defined as either $0$ or $1$, the \texttt{wxHAS} symbols are only defined if
the corresponding feature is available and not defined at all otherwise.
Currently the following symbols exist:
\begin{twocollist}\itemsep=0pt
\twocolitem{wxHAS\_LARGE\_FILES}{Defined if \helpref{wxFile}{wxfile} supports
files more than 4GB in size.}
\twocolitem{wxHAS\_LARGE\_FFILES}{Defined if \helpref{wxFFile}{wxffile}
supports files more than 4GB in size.}
\twocolitem{wxHAS\_POWER\_EVENTS}{Defined if
\helpref{wxPowerEvent}{wxpowerevent} are ever generated on the current platform.}
\twocolitem{wxHAS\_RADIO\_MENU\_ITEMS}{Defined if the current port supports
\helpref{radio menu items}{wxmenuappendradioitem}.}
\twocolitem{wxHAS\_RAW\_KEY\_CODES}{Defined if
\helpref{raw key codes}{wxkeyeventgetrawkeycode} are supported.}
\twocolitem{wxHAS\_REGEX\_ADVANCED}{Defined if advanced syntax is available in
\helpref{wxRegEx}{wxregex}.}
\twocolitem{wxHAS\_TASK\_BAR\_ICON}{Defined if
\helpref{wxTaskBarIcon}{wxtaskbaricon} is available on the current platform.}
