@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.
