/**
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:
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, the vendor name is used under
- Windows and OS X but not under other Unix systems, see UseAppInfo().
+ 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.
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.
