- These functions allow to examine and modify the individual directories
- of the path:
-
- @li AppendDir()
- @li InsertDir()
- @li GetDirCount()
- @li PrependDir()
- @li RemoveDir()
- @li RemoveLastDir()
-
- To change the components of the file name individually you can use the
- following functions:
-
- @li GetExt()
- @li GetName()
- @li GetVolume()
- @li HasExt()
- @li HasName()
- @li HasVolume()
- @li SetExt()
- @li ClearExt()
- @li SetEmptyExt()
- @li SetName()
- @li SetVolume()
-
- You can initialize a wxFileName instance using one of the following functions:
-
- @li wxFileName()
- @li Assign()
- @li AssignCwd()
- @li AssignDir()
- @li AssignHomeDir()
- @li DirName()
- @li FileName()
-
- wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
- and VMS formats (Mac OS no longer being maintained as OS X uses the Unix notation).
- Although these formats are quite different, wxFileName tries to treat them all
- in the same generic way. It supposes that all file names consist of the following
- parts: the volume (also known as drive under Windows or device under VMS), the
- path which is a sequence of directory names separated by the
- @ref getpathseparators() "path separators"
- and the full filename itself which, in turn, is composed from the base file name
- and the extension. All of the individual components of the file name may be empty
- and, for example, the volume name is always empty under Unix, but if they are all
- empty simultaneously, the filename object is considered to be in an invalid
- state and IsOk() returns @false for it.
- File names can be case-sensitive or not, the function IsCaseSensitive() allows to
- determine this. The rules for determining whether the file name is absolute or
- relative also depend on the file name format and the only portable way to answer
- this question is to use IsAbsolute() or IsRelative() method. Note that on Windows,
- "X:" refers to the current working directory on drive X. Therefore, a wxFileName
- instance constructed from for example "X:dir/file.ext" treats the portion beyond
- drive separator as being relative to that directory. To ensure that the filename
- is absolute, you may use MakeAbsolute(). There is also an inverse function
- MakeRelativeTo() which undoes what Normalize(wxPATH_NORM_DOTS) does.
- Other functions returning information about the file format provided by this
- class are GetVolumeSeparator(), IsPathSeparator().
-
- Before doing other tests, you should use IsOk() to verify that the filename
- is well defined. If it is, FileExists() can be used to test whether a file
- with such name exists and DirExists() can be used to test for directory existence.
- File names should be compared using the SameAs() method or operator=(). For testing
- basic access modes, you can use:
-
- @li IsDirWritable()
- @li IsDirReadable()
- @li IsFileWritable()
- @li IsFileReadable()
- @li IsFileExecutable()
-
- These methods allow to work with the file creation, access and modification
- times. Note that not all filesystems under all platforms implement these times
- in the same way. For example, the access time under Windows has a resolution of
- one day (so it is really the access date and not time). The access time may be
- updated when the file is executed or not depending on the platform.
-
- @li GetModificationTime()
- @li GetTimes()
- @li SetTimes()
- @li Touch()
-
- Other file system operations functions are:
-
- @li Mkdir()
- @li Rmdir()
+ Please note that many wxFileName methods accept the path format argument
+ which is by @c wxPATH_NATIVE by default meaning to use the path format
+ native for the current platform.
+ The path format affects the operation of wxFileName functions in several ways:
+ first and foremost, it defines the path separator character to use, but it
+ also affects other things such as whether the path has the drive part or not.
+ See wxPathFormat for more info.
