  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_BEOS = wxPATH_UNIX,
  42     wxPATH_MAC,
  43     wxPATH_DOS,
  44     wxPATH_WIN = wxPATH_DOS,
  45     wxPATH_OS2 = wxPATH_DOS,
  46     wxPATH_VMS,
  47
  48     wxPATH_MAX // Not a valid value for specifying path format
  49 }
  50 \end{verbatim}

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

 192
 193 \func{static void}{AssignCwd}{\param{const wxString\& }{volume = wxEmptyString}}
 194
 195 Makes this object refer to the current working directory on the specified
 196 volume (or current volume if {\it volume} is empty).

 199
 200 \helpref{GetCwd}{wxfilenamegetcwd}
 201
 202 \membersection{wxFileName::AssignDir}\label{wxfilenameassigndir}
 203
 204 \func{void}{AssignDir}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
 205
 206 Sets this file name object to the given directory name. The name and extension
 207 will be empty.
 208
 209 \membersection{wxFileName::AssignHomeDir}\label{wxfilenameassignhomedir}
 210
 211 \func{void}{AssignHomeDir}{\void}
 212
 213 Sets this file name object to the home directory.

 216
 217 \func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
 218
 219 The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to
 220 create a temporary file and sets this object to the name of the file. If a
 221 temporary file couldn't be created, the object is put into the\rtfsp
 222 \helpref{invalid}{wxfilenameisok} state.
 223
 224 \membersection{wxFileName::Clear}\label{wxfilenameclear}
 225
 226 \func{void}{Clear}{\void}
 227
 228 Reset all components to default, uninitialized state.
 229
 230 \membersection{wxFileName::CreateTempFileName}\label{wxfilenamecreatetempfilename}
 231
 232 \func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}
 233
 234 Returns a temporary file name starting with the given {\it prefix}. If
 235 the {\it prefix} is an absolute path, the temporary file is created in this
 236 directory, otherwise it is created in the default system directory for the
 237 temporary files or in the current directory.
 238
 239 If the function succeeds, the temporary file is actually created. If\rtfsp
 240 {\it fileTemp} is not {\tt NULL}, this file will be opened using the name of
 241 the temporary file. When possible, this is done in an atomic way ensuring that
 242 no race condition occurs between the temporary file name generation and opening
 243 it which could often lead to security compromise on the multiuser systems.
 244 If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened.
 245
 246 Under Unix, the temporary file will have read and write permissions for the
 247 owner only to minimize the security problems.
 248
 249 \wxheading{Parameters}
 250
 251 \docparam{prefix}{Prefix to use for the temporary file name construction}
 252
 253 \docparam{fileTemp}{The file to open or {\tt NULL} to just get the name}
 254
 255 \wxheading{Return value}

 290 \func{static wxFileName}{FileName}{\param{const wxString\& }{file}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
 291
 292 Returns the file name object corresponding to the given {\it file}. This
 293 function exists mainly for symmetry with \helpref{DirName}{wxfilenamedirname}.
 294

 380
 381 \constfunc{wxString}{GetPath}{\param{int }{flags = {\tt wxPATH\_GET\_VOLUME}}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
 382
 383 Returns the path part of the filename (without the name or extension). The
 384 possible flags values are:
 385
 386 \twocolwidtha{5cm}
 387 \begin{twocollist}\itemsep=0pt
 388 \twocolitem{{\bf wxPATH\_GET\_VOLUME}}{Return the path with the volume (does

 397
 398 \func{static wxChar}{GetPathSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
 399
 400 Returns the usually used path separator for this format. For all formats but
 401 {\tt wxPATH\_DOS} there is only one path separator anyhow, but for DOS there

 429
 430 \constfunc{bool}{GetTimes}{\param{wxDateTime* }{dtAccess}, \param{wxDateTime* }{dtMod}, \param{wxDateTime* }{dtCreate}}
 431
 432 Returns the last access, last modification and creation times. The last access
 433 time is updated whenever the file is read or written (or executed in the case
 434 of Windows), last modification time is only changed when the file is written
 435 to. Finally, the creation time is indeed the time when the file was created
 436 under Windows and the inode change time under Unix (as it is impossible to
 437 retrieve the real file creation time there anyhow) which can also be changed
 438 by many operations after the file creation.
 439
 440 Any of the pointers may be {\tt NULL} if the corresponding time is not
 441 needed.
 442
 443 \wxheading{Return value}
 444
 445 {\tt true} on success, {\tt false} if we failed to retrieve the times.
 446

 449 \constfunc{wxString}{GetVolume}{\void}
 450
 451 Returns the string containing the volume for this file name, mepty if it
 452 doesn't have one or if the file system doesn't support volumes at all (for
 453 example, Unix).
 454
 455 \membersection{wxFileName::GetVolumeSeparator}\label{wxfilenamegetvolumeseparator}
 456
 457 \func{static wxString}{GetVolumeSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
 458

 482
 483 Inserts a directory before the zero-based position in the directory list.
 484
 485 \membersection{wxFileName::IsAbsolute}\label{wxfilenameisabsolute}
 486
 487 \func{bool}{IsAbsolute}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
 488
 489 Returns {\tt true} if this filename is absolute.
 490
 491 \membersection{wxFileName::IsCaseSensitive}\label{wxfilenameiscasesensitive}
 492
 493 \func{static bool}{IsCaseSensitive}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
 494
 495 Returns {\tt true} if the file names of this type are case-sensitive.
 496
 497 \membersection{wxFileName::IsOk}\label{wxfilenameisok}
 498
 499 \constfunc{bool}{IsOk}{\void}
 500
 501 Returns {\tt true} if the filename is valid, {\tt false} if it is not
 502 initialized yet. The assignment functions and
 503 \helpref{Clear}{wxfilenameclear} may reset the object to the uninitialized,
 504 invalid state (the former only do it on failure).
 505
 506 \membersection{wxFileName::IsPathSeparator}\label{wxfilenameispathseparator}
 507
 508 \func{static bool}{IsPathSeparator}{\param{wxChar }{ch}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
 509
 510 Returns {\tt true} if the char is a path separator for this format.
 511
 512 \membersection{wxFileName::IsRelative}\label{wxfilenameisrelative}
 513
 514 \func{bool}{IsRelative}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}
 515
 516 Returns {\tt true} if this filename is not absolute.
 517
 518 \membersection{wxFileName::IsDir}\label{wxfilenameisdir}
 519
 520 \constfunc{bool}{IsDir}{\void}
 521
 522 Returns {\tt true} if this object represents a directory, {\tt false} otherwise
 523 (i.e. if it is a file). Note that this method doesn't test whether the
 524 directory or file really exists, you should use
 525 \helpref{DirExists}{wxfilenamedirexists} or
 526 \helpref{FileExists}{wxfilenamefileexists} for this.
 527
 528 \membersection{wxFileName::MakeAbsolute}\label{wxfilenamemakeabsolute}
 529
 530 \func{bool}{MakeAbsolute}{\param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
 531
 532 Make the file name absolute. This is a shortcut for
 533 {\tt \helpref{Normalize}{wxfilenamenormalize}(wxPATH\_NORM\_DOTS | wxPATH\_NORM\_ABSOLUTE | wxPATH\_NORM\_TILDE, cwd, format)}.

 544
 545 This function tries to put this file name in a form relative to {\it pathBase}.
 546 In other words, it returns the file name which should be used to access this
 547 file if the current directory were {\it pathBase}.

 554 \wxheading{Return value}
 555
 556 {\tt true} if the file name has been changed, {\tt false} if we failed to do
 557 anything with it (currently this only happens if the file name is on a volume
 558 different from the volume specified by {\it pathBase}).

 678
 679 This function splits a full file name into components: the volume (with the
 680 first version) path (including the volume in the second version), the base name
 681 and the extension. Any of the output parameters ({\it volume}, {\it path},
 682 {\it name} or {\it ext}) may be {\tt NULL} if you are not interested in the
 683 value of a particular component. Also, {\it fullpath} may be empty on entry.
 684
 685 On return, {\it path} contains the file path (without the trailing separator),
 686 {\it name} contains the file name and {\it ext} contains the file extension
 687 without leading dot. All three of them may be empty if the corresponding
 688 component is. The old contents of the strings pointed to by these parameters
 689 will be overwritten in any case (if the pointers are not {\tt NULL}).
