///////////////////////////////////////////////////////////////////////////// // Name: stdpaths.h // Purpose: interface of wxStandardPaths // Author: wxWidgets team // RCS-ID: $Id$ // Licence: wxWindows license ///////////////////////////////////////////////////////////////////////////// /** @class wxStandardPaths wxStandardPaths returns the standard locations in the file system and should be 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. For example, under Windows: the system administrator may change the standard directories locations, i.e. the Windows directory may be named @c "W:\Win2003" instead of the default @c "C:\Windows". The strings @c appname and @c username should be replaced with the value returned by wxApp::GetAppName() and the name of the currently logged in user, respectively. The string @c prefix is only used under Unix and is @c /usr/local by default but may be changed using wxStandardPaths::SetInstallPrefix. 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 @c wxStandardPaths::Get on which you call the desired methods. @library{wxbase} @category{file} @see wxFileConfig */ class wxStandardPaths { public: /** Returns reference to the unique global standard paths object. */ static wxStandardPaths& Get(); /** Return the directory for the document files used by this application.
