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 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".
- 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.
+ 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
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.
