  13
  14 wxStandardPaths returns the standard locations in the file system and should be
  15 used by applications to find their data files in a portable way.
  16
  17 In the description of the methods below, the example return values are given
  18 for the Unix, Windows and Mac OS X systems, however please note that these are
  19 just the examples and the actual values may differ. For example, under Windows:
  20 the system administrator may change the standard directories locations, i.e.
  21 the Windows directory may be named \texttt{W:$\backslash$Win2003} instead of
  22 the default \texttt{C:$\backslash$Windows}.
  23
  24 The strings \texttt{\textit{appname}} and \texttt{\textit{username}} should be
  25 replaced with the value returned by \helpref{wxApp::GetAppName}{wxappgetappname}
  26 and the name of the currently logged in user, respectively. The string
  27 \texttt{\textit{prefix}} is only used under Unix and is \texttt{/usr/local} by
  28 default but may be changed using \helpref{SetInstallPrefix}{wxstandardpathssetinstallprefix}.
  29
  30 The directories returned by the methods of this class may or may not exist. If
  31 they don't exist, it's up to the caller to create them, wxStandardPaths doesn't
  32 do it.
  33
  34 Finally note that these functions only work with standardly packaged
  35 applications. I.e. under Unix you should follow the standard installation
  36 conventions and under Mac you should create your application bundle according
  37 to the Apple guidelines. Again, this class doesn't help you to do it.
  38
  39 This class is MT-safe: its methods may be called concurrently from different
  40 threads without additional locking.

  54 \membersection{wxStandardPaths::Get}\label{wxstandardpathsget}
  55
  56 \func{static wxStandardPathsBase\&}{Get}{\void}
  57
  58 Returns reference to the unique global standard paths object.
  59
  60
  61 \membersection{wxStandardPaths::GetConfigDir}\label{wxstandardpathsgetconfigdir}
  62
  63 \func{wxString}{GetConfigDir}{\void}
  64
  65 Return the directory containing the system config files.
  66
  67 Example return values:
  68 \begin{itemize}
  69     \item Unix: \texttt{/etc}
  70     \item Windows: \texttt{C:$\backslash$Documents and Settings$\backslash$All Users$\backslash$Application Data}
  71     \item Mac: \texttt{/Library/Preferences}

  79 \membersection{wxStandardPaths::GetDataDir}\label{wxstandardpathsgetdatadir}
  80
  81 \func{wxString}{GetDataDir}{\void}
  82
  83 Return the location of the applications global, i.e. not user-specific,
  84 data files.
  85
  86 Example return values:
  87 \begin{itemize}
  88     \item Unix: \texttt{\textit{prefix}/share/\textit{appname}}
  89     \item Windows: the directory where the executable file is located
  90     \item Mac: \texttt{\textit{appname}.app/Contents/SharedSupport} bundle subdirectory
  91 \end{itemize}

  97
  98 \membersection{wxStandardPaths::GetInstallPrefix}\label{wxstandardpathsgetinstallprefix}
  99
 100 \func{wxString}{GetInstallPrefix}{\void}
 101
 102 \textbf{Note: } This function is only available under Unix.
 103
 104 Return the program installation prefix, e.g. \texttt{/usr}, \texttt{/opt} or
 105 \texttt{/home/zeitlin}.
 106
 107 If the prefix had been previously by
 108 \helpref{SetInstallPrefix}{wxstandardpathssetinstallprefix}, returns that
 109 value, otherwise tries to determine it automatically (Linux only right
 110 now) and finally returns the default \texttt{/usr/local} value if it failed.
 111
 112
 113 \membersection{wxStandardPaths::GetLocalDataDir}\label{wxstandardpathsgetlocaldatadir}
 114
 115 \func{wxString}{GetLocalDataDir}{\void}
 116
 117 Return the location for application data files which are host-specific and
 118 can't, or shouldn't, be shared with the other machines.
 119
 120 This is the same as \helpref{GetDataDir()}{wxstandardpathsgetdatadir} except
 121 under Unix where it returns \texttt{/etc/\textit{appname}}.
 122
 123
 124 \membersection{wxStandardPaths::GetPluginsDir}\label{wxstandardpathsgetpluginsdir}
 125
 126 \func{wxString}{GetPluginsDir}{\void}
 127
 128 Return the directory where the loadable modules (plugins) live.
 129
 130 Example return values:
 131 \begin{itemize}
 132     \item Unix: \texttt{\textit{prefix}/lib/\textit{appname}}
 133     \item Windows: the directory of the executable file
 134     \item Mac: \texttt{\textit{appname}.app/Contents/PlugIns} bundle subdirectory
 135 \end{itemize}

 140
 141
 142 \membersection{wxStandardPaths::GetUserConfigDir}\label{wxstandardpathsgetuserconfigdir}
 143
 144 \func{wxString}{GetUserConfigDir}{\void}
 145
 146 Return the directory for the user config files:
 147 \begin{itemize}
 148     \item Unix: \tt{~} (the home directory)
 149     \item Windows: \tt{C:$\backslash$Documents and Settings$\backslash$\textit{username}}
 150     \item Mac: \tt{~/Library/Preferences}
 151 \end{itemize}
 152
 153 Only use this method if you have a single configuration file to put in this
 154 directory, otherwise \helpref{GetUserDataDir()}{wxstandardpathsgetuserdatadir} is
 155 more appropriate.
 156
 157
 158 \membersection{wxStandardPaths::GetUserDataDir}\label{wxstandardpathsgetuserdatadir}
 159
 160 \func{wxString}{GetUserDataDir}{\void}
 161
 162 Return the directory for the user-dependent application data files:
 163 \begin{itemize}
 164     \item Unix: \tt{~/.\textit{appname}}
 165     \item Windows: \tt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Application Data$\backslash$\textit{appname}}
 166     \item Mac: \tt{~/Library/Application Support/\textit{appname}}
 167 \end{itemize}
 168
 169
 170 \membersection{wxStandardPaths::GetUserLocalDataDir}\label{wxstandardpathsgetuserlocaldatadir}
 171
 172 \func{wxString}{GetUserLocalDataDir}{\void}
 173
 174 Return the directory for user data files which shouldn't be shared with
 175 the other machines.
 176
 177 This is the same as \helpref{GetUserDataDir()}{wxstandardpathsgetuserdatadir} for
 178 all platforms except Windows where it returns
 179 \texttt{C:$\backslash$Documents and Settings$\backslash$\textit{username}$\backslash$Local Settings$\backslash$Application Data$\backslash$\textit{appname}}
 180
 181
 182 \membersection{wxStandardPaths::SetInstallPrefix}\label{wxstandardpathssetinstallprefix}
 183
 184 \func{void}{SetInstallPrefix}{\param{const wxString\& }{prefix}}
 185
 186 \textbf{Note:} This function is only available under Unix.
 187
 188 Lets wxStandardPaths know about the real program installation prefix on a Unix
 189 system. By default, the value returned by
 190 \helpref{GetInstallPrefix}{wxstandardpathsgetinstallprefix} is used.
 191
 192 Although under Linux systems the program prefix may usually be determined
 193 automatically, portable programs should call this function. Usually the prefix
 194 is set during program configuration if using GNU autotools and so it is enough
 195 to pass its value defined in \texttt{config.h} to this function.
