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. 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. 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 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. Note that you don't allocate an instance of class wxStandardPaths, but retrieve the global standard paths object using \texttt{wxStandardPaths::Get} on which you call the desired methods. \wxheading{Derived from} No base class \wxheading{Include files} \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxStandardPaths::Get}\label{wxstandardpathsget} \func{static wxStandardPathsBase\&}{Get}{\void} Returns reference to the unique global standard paths object. \membersection{wxStandardPaths::GetConfigDir}\label{wxstandardpathsgetconfigdir} \constfunc{wxString}{GetConfigDir}{\void} Return the directory containing the system config files. Example return values: \begin{itemize} \item Unix: \texttt{/etc} \item Windows: \texttt{C:$\backslash$Documents and Settings$\backslash$All Users$\backslash$Application Data} \item Mac: \texttt{/Library/Preferences} \end{itemize} \wxheading{See also} \helpref{wxFileConfig}{wxfileconfig} \membersection{wxStandardPaths::GetDataDir}\label{wxstandardpathsgetdatadir} \constfunc{wxString}{GetDataDir}{\void} Return the location of the applications global, i.e. not user-specific, data files. Example return values: \begin{itemize} \item Unix: \texttt{\textit{prefix}/share/\textit{appname}} \item Windows: the directory where the executable file is located \item Mac: \texttt{\textit{appname}.app/Contents/SharedSupport} bundle subdirectory \end{itemize} \wxheading{See also} \helpref{GetLocalDataDir}{wxstandardpathsgetlocaldatadir} \membersection{wxStandardPaths::GetDocumentsDir}\label{wxstandardpathsgetdocumentsdir} \constfunc{wxString}{GetDocumentsDir}{\void} Return the directory containing the current user's documents. Example return values: \begin{itemize} \item Unix: \tt{~} (the home directory) \item Windows: \texttt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Documents} \item Mac: \texttt{~/Documents} \end{itemize} \newsince{2.7.0} \membersection{wxStandardPaths::GetExecutablePath}\label{wxstandardpathsgetexecutablepath} \constfunc{wxString}{GetExecutablePath}{\void} Return the directory and the filename for the current executable. Example return values: \begin{itemize} \item Unix: \texttt{/usr/local/bin/exename} \item Windows: \texttt{C:$\backslash$Programs$\backslash$AppFolder$\backslash$exename.exe} \item Mac: \texttt{/Programs/exename} \end{itemize} \membersection{wxStandardPaths::GetInstallPrefix}\label{wxstandardpathsgetinstallprefix} \constfunc{wxString}{GetInstallPrefix}{\void} \textbf{Note: } This function is only available under Unix. Return the program installation prefix, e.g. \texttt{/usr}, \texttt{/opt} or \texttt{/home/zeitlin}. If the prefix had been previously by \helpref{SetInstallPrefix}{wxstandardpathssetinstallprefix}, returns that value, otherwise tries to determine it automatically (Linux only right now) and finally returns the default \texttt{/usr/local} value if it failed. \membersection{wxStandardPaths::GetLocalDataDir}\label{wxstandardpathsgetlocaldatadir} \constfunc{wxString}{GetLocalDataDir}{\void} Return the location for application data files which are host-specific and can't, or shouldn't, be shared with the other machines. This is the same as \helpref{GetDataDir()}{wxstandardpathsgetdatadir} except under Unix where it returns \texttt{/etc/\textit{appname}}. \membersection{wxStandardPaths::GetLocalizedResourcesDir}\label{wxstandardpathsgetlocalizedresourcesdir} \constfunc{wxString}{GetLocalizedResourcesDir}{\param{const wxChar*}{ lang}, \param{ResourceCat}{ category = ResourceCat\_None}} Return the localized resources directory containing the resource files of the specified category for the given language. In general this is just the same as \arg{lang} subdirectory of \helpref{GetResourcesDir()}{wxstandardpathsgetresourcesdir} (or \texttt{\arg{lang}.lproj} under Mac OS X) but is something quite different for message catalog category under Unix where it returns the standard \texttt{\textit{prefix}/share/locale/\arg{lang}/LC\_MESSAGES} directory. \newsince{2.7.0} \membersection{wxStandardPaths::GetPluginsDir}\label{wxstandardpathsgetpluginsdir} \constfunc{wxString}{GetPluginsDir}{\void} Return the directory where the loadable modules (plugins) live. Example return values: \begin{itemize} \item Unix: \texttt{\textit{prefix}/lib/\textit{appname}} \item Windows: the directory of the executable file \item Mac: \texttt{\textit{appname}.app/Contents/PlugIns} bundle subdirectory \end{itemize} \wxheading{See also} \helpref{wxDynamicLibrary}{wxdynamiclibrary} \membersection{wxStandardPaths::GetResourcesDir}\label{wxstandardpathsgetresourcesdir} \constfunc{wxString}{GetResourcesDir}{\void} Return the directory where the application resource files are located. The resources are the auxiliary data files needed for the application to run and include, for example, image and sound files it might use. This function is the same as \helpref{GetDataDir}{wxstandardpathsgetdatadir} for all platforms except Mac OS X. Example return values: \begin{itemize} \item Unix: \texttt{\textit{prefix}/share/\textit{appname}} \item Windows: the directory where the executable file is located \item Mac: \texttt{\textit{appname}.app/Contents/Resources} bundle subdirectory \end{itemize} \newsince{2.7.0} \wxheading{See also} \helpref{GetLocalizedResourcesDir}{wxstandardpathsgetlocalizedresourcesdir} \membersection{wxStandardPaths::GetTempDir}\label{wxstandardpathsgettempdir} \constfunc{wxString}{GetTempDir}{\void} Return the directory for storing temporary files. To create unique temporary files, it is best to use \helpref{wxFileName::CreateTempFileName}{wxfilenamecreatetempfilename} for correct behaviour when multiple processes are attempting to create temporary files. \newsince{2.7.2} \membersection{wxStandardPaths::GetUserConfigDir}\label{wxstandardpathsgetuserconfigdir} \constfunc{wxString}{GetUserConfigDir}{\void} Return the directory for the user config files: \begin{itemize} \item Unix: \tt{~} (the home directory) \item Windows: \tt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Application Data} \item Mac: \tt{~/Library/Preferences} \end{itemize} Only use this method if you have a single configuration file to put in this directory, otherwise \helpref{GetUserDataDir()}{wxstandardpathsgetuserdatadir} is more appropriate. \membersection{wxStandardPaths::GetUserDataDir}\label{wxstandardpathsgetuserdatadir} \constfunc{wxString}{GetUserDataDir}{\void} Return the directory for the user-dependent application data files: \begin{itemize} \item Unix: \tt{~/.\textit{appname}} \item Windows: \tt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Application Data$\backslash$\textit{appname}} \item Mac: \tt{~/Library/Application Support/\textit{appname}} \end{itemize} \membersection{wxStandardPaths::GetUserLocalDataDir}\label{wxstandardpathsgetuserlocaldatadir} \constfunc{wxString}{GetUserLocalDataDir}{\void} Return the directory for user data files which shouldn't be shared with the other machines. This is the same as \helpref{GetUserDataDir()}{wxstandardpathsgetuserdatadir} for all platforms except Windows where it returns \texttt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Local Settings$\backslash$Application Data$\backslash$\textit{appname}} \membersection{wxStandardPaths::SetInstallPrefix}\label{wxstandardpathssetinstallprefix} \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.
