wxStandardPaths returns the standard locations in the file system and should be
-used by the programs to find their data files in a portable way.
-
-Please note that this is not a real class because object of this type are never
-created but more a namespace containing the class methods which are all static,
-so to use wxStandardPaths simply call its methods directly.
+used by applications to find their data files in a portable way.
In the description of the methods below, the example return values are given
for the Unix, Windows and Mac OS X systems, however please note that these are
-just the examples and the actual values may differ. Most importantly:
-\begin{itemize}
- \item Unix: \texttt{/usr} should in general be replaced by the
- program installation prefix which is by default \texttt{/usr/local} but
- may be any other path as well.
- \item Windows: the system administrator may change the standard
- directories locations, i.e. the Windows directory may be named
- \texttt{W:$\backslash$Win2003} instead of default
- \texttt{C:$\backslash$Windows}
-\end{itemize}
+just the examples and the actual values may differ. For example, under Windows:
+the system administrator may change the standard directories locations, i.e.
+the Windows directory may be named \texttt{W:$\backslash$Win2003} instead of
+the default \texttt{C:$\backslash$Windows}.
The strings \texttt{\textit{appname}} and \texttt{\textit{username}} should be
replaced with the value returned by \helpref{wxApp::GetAppName}{wxappgetappname}
-and the name of the currently logged in user, respectively.
+and the name of the currently logged in user, respectively. The string
+\texttt{\textit{prefix}} is only used under Unix and is \texttt{/usr/local} by
+default but may be changed using \helpref{SetInstallPrefix}{wxstandardpathssetinstallprefix}.
The directories returned by the methods of this class may or may not exist. If
they don't exist, it's up to the caller to create them, wxStandardPaths doesn't
do it.
-Finally note that under Mac, these functions only work for the bundled
-applications.
+Finally note that these functions only work with standardly packaged
+applications. I.e. under Unix you should follow the standard installation
+conventions and under Mac you should create your application bundle according
+to the Apple guidelines. Again, this class doesn't help you to do it.
+
+This class is MT-safe: its methods may be called concurrently from different
+threads without additional locking.

+\func{void}{SetInstallPrefix}{\param{const wxString\& }{prefix}}
+
+\textbf{Note:} This function is only available under Unix.
+
+Lets wxStandardPaths know about the real program installation prefix on a Unix
+system. By default, the value returned by
+\helpref{GetInstallPrefix}{wxstandardpathsgetinstallprefix} is used.
+
+Although under Linux systems the program prefix may usually be determined
+automatically, portable programs should call this function. Usually the prefix
+is set during program configuration if using GNU autotools and so it is enough
+to pass its value defined in \texttt{config.h} to this function.
