/**
wxStandardPaths returns the standard locations in the file system and should be
used by applications to find their data files in a portable way.
+ Note that you must not create objects of class wxStandardPaths directly,
+ but use the global standard paths object returned by wxStandardPaths::Get()
+ (which can be of a type derived from wxStandardPaths and not of exactly
+ this type) and call the methods you need on it. The object returned by
+ Get() may be customized by overriding wxAppTraits::GetStandardPaths()
+ methods.
+
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
+ the system administrator may change the standard directories locations, e.g.
+ the Windows directory may be named @c "W:\Win2003" instead of
+ the default @c "C:\Windows".
+
+ Notice that in the examples below the string @c appinfo may be either just
+ the application name (as returned by wxApp::GetAppName()) or a combination
+ of the vendor name (wxApp::GetVendorName()) and the application name, with
+ a path separator between them. By default, only the application name is
+ used, use UseAppInfo() to change this.
+
+ The other placeholders should be self-explanatory: the string @c username
+ should be replaced with the value the name of the currently logged in user.
+ and @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
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.
