12 \section{\class{wxFileName}}\label{wxfilename}
13
14 wxFileName encapsulates a file name. This class serves two purposes: first, it
15 provides the functions to split the file names into components and to recombine
16 these components in the full file name which can then be passed to the OS file
17 functions (and \helpref{wxWindows functions}{filefunctions} wrapping them).
18 Second, it includes the functions for working with the files itself. Note that
19 to change the file data you should use \helpref{wxFile}{wxfile} class instead.
20 wxFileName provides functions for working with the file attributes.

26 \wxheading{Data structures}
27
28 Many wxFileName methods accept the path format argument which is by\rtfsp
29 {\tt wxPATH\_NATIVE} by default meaning to use the path format native for the
30 current platform.
31
32 The path format affects the operation of wxFileName functions in several ways:
33 first and foremost, it defines the path separator character to use, but it also
34 affects other things such as whether the path has the drive part or not.
35
36 \begin{verbatim}
37 enum wxPathFormat
38 {
39 wxPATH_NATIVE = 0, // the path format for the current platform
40 wxPATH_UNIX,
41 wxPATH_MAC,
42 wxPATH_DOS,
43 wxPATH_VMS,
44
45 wxPATH_BEOS = wxPATH_UNIX,
46 wxPATH_WIN = wxPATH_DOS,
47 wxPATH_OS2 = wxPATH_DOS
48 }
49 \end{verbatim}

53 \membersection{File name format}
54
55 wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
56 and VMS formats. Although these formats are quite different, wxFileName tries
57 to treat them all in the same generic way. It supposes that all file names
58 consist of the following parts: the volume (also known as drive under Windows
59 or device under VMS), the path which is a sequence of directory names separated
60 by the \helpref{path separators}{wxfilenamegetpathseparators} and the full
61 filename itself which, in turn, is composed from the base file name and the
62 extension. All of the individual components of the file name may be empty and,
63 for example, the volume name is always empty under Unix, but if they are all
64 empty simultaneously, the filename object is considered to be in an invalid
65 state and \helpref{IsOk}{wxfilenameisok} returns {\tt false} for it.
66
67 File names can be case-sensitive or not, the function\rtfsp
68 \helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this.
69
70 The rules for determining if the file name is absolute or relative also depends
71 on the file name format and the only portable way to answer to this question is
72 to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
73 filename is absolute you may use \helpref{MakeAbsolute}{wxfilenamemakeabsolute}.
74 There is also an inverse function
75 \helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what
76 \helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does.
77
78 Other functions returning information about the file format provided by this
79 class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp
80 \helpref{IsPathSeparator}{wxfilenameispathseparator}.
81
82 \helpref{IsRelative}{wxfilenameisrelative}
83
84 \membersection{File name construction}
85
86 TODO.
87
88 \membersection{File tests}
89
90 Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
91 verify that the filename is well defined. If it is,
92 \helpref{FileExists}{wxfilenamefileexists} can be used to test if a file with
93 such name exists and \helpref{DirExists}{wxfilenamedirexists} - if a directory
94 with this name exists.
95
96 File names should be compared using \helpref{SameAs}{wxfilenamesameas} method
97 or \helpref{$==$}{wxfilenameoperatorequal}.
98
99 \membersection{File name components}
100
101 These functions allow to examine and modify the directories of the path:
102
103 \helpref{AppendDir}{wxfilenameappenddir}\\
104 \helpref{InsertDir}{wxfilenameinsertdir}\\
105 \helpref{GetDirCount}{wxfilenamegetdircount}
106 \helpref{PrependDir}{wxfilenameprependdir}\\
107 \helpref{RemoveDir}{wxfilenameremovedir}
108
109 To change the components of the file name individually you can use the
110 following functions:
111
112 \helpref{GetExt}{wxfilenamegetext}\\
113 \helpref{GetName}{wxfilenamegetname}\\
114 \helpref{GetVolume}{wxfilenamegetvolume}\\
115 \helpref{HasExt}{wxfilenamehasext}\\
116 \helpref{HasName}{wxfilenamehasname}\\
117 \helpref{HasVolume}{wxfilenamehasvolume}\\
118 \helpref{SetExt}{wxfilenamesetext}\\
119 \helpref{SetName}{wxfilenamesetname}\\
120 \helpref{SetVolume}{wxfilenamesetvolume}\\
121
122 \membersection{Operations}
123
124 These methods allow to work with the file creation, access and modification
125 times. Note that not all filesystems under all platforms implement these times
126 in the same way. For example, the access time under Windows has a resolution of
127 one day (so it is really the access date and not time). The access time may be
128 updated when the file is executed or not depending on the platform.
129
130 \helpref{GetModificationTime}{wxfilenamegetmodificationtime}\\
131 \helpref{GetTimes}{wxfilenamegettimes}\\
132 \helpref{SetTimes}{wxfilenamesettimes}\\
133 \helpref{Touch}{wxfilenametouch}
134
135 Other file system operations functions are:
136
137 \helpref{Mkdir}{wxfilenamemkdir}\\
138 \helpref{Rmdir}{wxfilenamermdir}

181
182 \func{void}{Assign}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
183
184 \func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
185

187
188 Creates the file name from various combinations of data.
189
190 \membersection{wxFileName::AssignCwd}\label{wxfilenameassigncwd}
191
192 \func{void}{AssignCwd}{\param{const wxString\& }{volume = ""}}
193
194 Makes this object refer to the current working directory on the specified
195 volume (or current volume if {\it volume} is empty).
196
197 \wxheading{See also}
198
199 \helpref{GetCwd}{wxfilenamegetcwd}
200
201 \membersection{wxFileName::AssignDir}\label{wxfilenameassigndir}
202
203 \func{void}{AssignDir}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
204
205 Sets this file name object to the given directory name. The name and extension
206 will be empty.
207
208 \membersection{wxFileName::AssignHomeDir}\label{wxfilenameassignhomedir}
209
210 \func{void}{AssignHomeDir}{\void}
211
212 Sets this file name object to the home directory.
213
214 \membersection{wxFileName::AssignTempFileName}\label{wxfilenameassigntempfilename}
215
216 \func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
217
218 The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to
219 create a temporary file and sets this object to the name of the file. If a
220 temporary file couldn't be created, the object is put into the\rtfsp
221 \helpref{invalid}{wxfilenameisok} state.
222
223 \membersection{wxFileName::Clear}\label{wxfilenameclear}
224
225 \func{void}{Clear}{\void}
226

228
229 \membersection{wxFileName::CreateTempFileName}\label{wxfilenamecreatetempfilename}
230
231 \func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
232
233 Returns a temporary file name starting with the given {\it prefix}. If
234 the {\it prefix} is an absolute path, the temporary file is created in this
235 directory, otherwise it is created in the default system directory for the
236 temporary files or in the current directory.
237
238 If the function succeeds, the temporary file is actually created. If\rtfsp
239 {\it fileTemp} is not {\tt NULL}, this file will be opened using the name of
240 the temporary file. When possible, this is done in an atomic way ensuring that
241 no race condition occurs between the temporary file name generation and opening
242 it which could often lead to security compromise on the multiuser systems.
243 If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened.
244
245 Under Unix, the temporary file will have read and write permissions for the
246 owner only to minimize the security problems.
247
248 \wxheading{Parameters}
249
250 \docparam{prefix}{Prefix to use for the temporary file name construction}
251
252 \docparam{fileTemp}{The file to open or {\tt NULL} to just get the name}

368
369 \constfunc{wxString}{GetPath}{\param{int }{flags = $0$}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
370
371 Returns the path part of the filename (without the name or extension). The
372 possible flags values are:

385 \func{wxChar}{GetPathSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
386
387 Returns the usually used path separator for this format. For all formats but
388 {\tt wxPATH\_DOS} there is only one path separator anyhow, but for DOS there

416
417 \constfunc{bool}{GetTimes}{\param{wxDateTime* }{dtAccess}, \param{wxDateTime* }{dtMod}, \param{wxDateTime* }{dtCreate}}
418
419 Returns the last access, last modification and creation times. The last access
420 time is updated whenever the file is read or written (or executed in the case
421 of Windows), last modification time is only changed when the file is written
422 to. Finally, the creation time is indeed the time when the file was created
423 under Windows and the inode change time under Unix (as it is impossible to
424 retrieve the real file creation time there anyhow) which can also be changed
425 by many operations after the file creation.
426
427 Any of the pointers may be {\tt NULL} if the corresponding time is not
428 needed.
429
430 \wxheading{Return value}
431
432 {\tt true} on success, {\tt false} if we failed to retrieve the times.

436 \constfunc{wxString}{GetVolume}{\void}
437
438 Returns the string containing the volume for this file name, mepty if it
439 doesn't have one or if the file system doesn't support volumes at all (for
440 example, Unix).
441
442 \membersection{wxFileName::GetVolumeSeparator}\label{wxfilenamegetvolumeseparator}
443
444 \func{wxString}{GetVolumeSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
445
446 Returns the string separating the volume from the path for this format.

471
472 \membersection{wxFileName::IsAbsolute}\label{wxfilenameisabsolute}
473
474 \func{bool}{IsAbsolute}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
475
476 Returns true if this filename is absolute.

481
482 Returns true if the file names of this type are case-sensitive.
483
484 \membersection{wxFileName::IsOk}\label{wxfilenameisok}
485
486 \constfunc{bool}{IsOk}{\void}
487
488 Returns {\tt true} if the filename is valid, {\tt false} if it is not
489 initialized yet. The assignment functions and
490 \helpref{Clear}{wxfilenameclear} may reset the object to the uninitialized,
491 invalid state (the former only do it on failure).
492
493 \membersection{wxFileName::IsPathSeparator}\label{wxfilenameispathseparator}
494
495 \func{bool}{IsPathSeparator}{\param{wxChar }{ch}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
496
497 Returns {\tt true} if the char is a path separator for this format.
498
499 \membersection{wxFileName::IsRelative}\label{wxfilenameisrelative}
500
501 \func{bool}{IsRelative}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

504
505 \membersection{wxFileName::IsDir}\label{wxfilenameisdir}
506
507 \constfunc{bool}{IsDir}{\void}
508
509 Returns {\tt true} if this object represents a directory, {\tt false} otherwise
510 (i.e. if it is a file). Note that this method doesn't test whether the
511 directory or file really exists, you should use
512 \helpref{DirExists}{wxfilenamedirexists} or
513 \helpref{FileExists}{wxfilenamefileexists} for this.
514
515 \membersection{wxFileName::MakeAbsolute}\label{wxfilenamemakeabsolute}
516
517 \func{bool}{MakeAbsolute}{\param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
518
519 Make the file name absolute. This is a shortcut for
520 {\tt \helpref{Normalize}{wxfilenamenormalize}(wxPATH\_NORM\_DOTS | wxPATH\_NORM\_ABSOLUTE | wxPATH\_NORM\_TILDE, cwd, format)}.

529
530 \func{bool}{MakeRelativeTo}{\param{const wxString\& }{pathBase = ""}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
531
532 This function tries to put this file name in a form relative to {\it pathBase}.
533 In other words, it returns the file name which should be used to access this
534 file if the current directory were {\it pathBase}.
535
536 \docparam{pathBase}{the directory to use as root, current directory is used by
537 default}
538
539 \docparam{format}{the file name format, native by default}
540
541 \wxheading{Return value}
542
543 {\tt true} if the file name has been changed, {\tt false} if we failed to do
544 anything with it (currently this only happens if the file name is on a volume
545 different from the volume specified by {\it pathBase}).

665
666 This function splits a full file name into components: the volume (with the
667 first version) path (including the volume in the second version), the base name
668 and the extension. Any of the output parameters ({\it volume}, {\it path},
669 {\it name} or {\it ext}) may be {\tt NULL} if you are not interested in the
670 value of a particular component. Also, {\it fullpath} may be empty on entry.
671
672 On return, {\it path} contains the file path (without the trailing separator),
673 {\it name} contains the file name and {\it ext} contains the file extension
674 without leading dot. All three of them may be empty if the corresponding
675 component is. The old contents of the strings pointed to by these parameters
676 will be overwritten in any case (if the pointers are not {\tt NULL}).
