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{wxWidgets 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 | } | |

55 | \membersection{File name format} | |
56 | ||
57 | wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS | |
58 | and VMS formats. Although these formats are quite different, wxFileName tries | |
59 | to treat them all in the same generic way. It supposes that all file names | |
60 | consist of the following parts: the volume (also known as drive under Windows | |
61 | or device under VMS), the path which is a sequence of directory names separated | |
62 | by the \helpref{path separators}{wxfilenamegetpathseparators} and the full | |
63 | filename itself which, in turn, is composed from the base file name and the | |
64 | extension. All of the individual components of the file name may be empty and, | |
65 | for example, the volume name is always empty under Unix, but if they are all | |
66 | empty simultaneously, the filename object is considered to be in an invalid | |
67 | state and \helpref{IsOk}{wxfilenameisok} returns {\tt false} for it. | |
68 | ||
69 | File names can be case-sensitive or not, the function\rtfsp | |
70 | \helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this. | |
71 | ||
72 | The rules for determining if the file name is absolute or relative also depends | |
73 | on the file name format and the only portable way to answer to this question is | |
74 | to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the | |
75 | filename is absolute you may use \helpref{MakeAbsolute}{wxfilenamemakeabsolute}. | |
76 | There is also an inverse function | |
77 | \helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what | |
78 | \helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does. | |
79 | ||
80 | Other functions returning information about the file format provided by this | |
81 | class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp | |
82 | \helpref{IsPathSeparator}{wxfilenameispathseparator}. | |
83 | ||
84 | \helpref{IsRelative}{wxfilenameisrelative} | |
85 | ||
86 | ||
87 | \membersection{File name construction} | |
88 | ||
89 | TODO. | |
90 | ||
91 | ||
92 | \membersection{File tests} | |
93 | ||
94 | Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to | |
95 | verify that the filename is well defined. If it is, | |
96 | \helpref{FileExists}{wxfilenamefileexists} can be used to test if a file with | |
97 | such name exists and \helpref{DirExists}{wxfilenamedirexists} - if a directory | |
98 | with this name exists. | |
99 | ||
100 | File names should be compared using \helpref{SameAs}{wxfilenamesameas} method | |
101 | or \helpref{$==$}{wxfilenameoperatorequal}. | |
102 | ||
103 | ||
104 | \membersection{File name components} | |
105 | ||
106 | These functions allow to examine and modify the directories of the path: | |
107 | ||
108 | \helpref{AppendDir}{wxfilenameappenddir}\\ | |
109 | \helpref{InsertDir}{wxfilenameinsertdir}\\ | |
110 | \helpref{GetDirCount}{wxfilenamegetdircount} | |
111 | \helpref{PrependDir}{wxfilenameprependdir}\\ | |
112 | \helpref{RemoveDir}{wxfilenameremovedir} | |
113 | ||
114 | To change the components of the file name individually you can use the | |
115 | following functions: | |
116 | ||
117 | \helpref{GetExt}{wxfilenamegetext}\\ | |
118 | \helpref{GetName}{wxfilenamegetname}\\ | |
119 | \helpref{GetVolume}{wxfilenamegetvolume}\\ | |
120 | \helpref{HasExt}{wxfilenamehasext}\\ | |
121 | \helpref{HasName}{wxfilenamehasname}\\ | |
122 | \helpref{HasVolume}{wxfilenamehasvolume}\\ | |
123 | \helpref{SetExt}{wxfilenamesetext}\\ | |
124 | \helpref{SetName}{wxfilenamesetname}\\ | |
125 | \helpref{SetVolume}{wxfilenamesetvolume}\\ | |
126 | ||
127 | ||
128 | \membersection{Operations} | |
129 | ||
130 | These methods allow to work with the file creation, access and modification | |
131 | times. Note that not all filesystems under all platforms implement these times | |
132 | in the same way. For example, the access time under Windows has a resolution of | |
133 | one day (so it is really the access date and not time). The access time may be | |
134 | updated when the file is executed or not depending on the platform. | |
135 | ||
136 | \helpref{GetModificationTime}{wxfilenamegetmodificationtime}\\ | |
137 | \helpref{GetTimes}{wxfilenamegettimes}\\ | |
138 | \helpref{SetTimes}{wxfilenamesettimes}\\ | |
139 | \helpref{Touch}{wxfilenametouch} | |
140 | ||
141 | Other file system operations functions are: | |
142 | ||
143 | \helpref{Mkdir}{wxfilenamemkdir}\\ | |
144 | \helpref{Rmdir}{wxfilenamermdir} | |

151 | \func{}{wxFileName}{\void} | |
152 | ||
153 | Default constructor. | |
154 | ||
155 | \func{}{wxFileName}{\param{const wxFileName\& }{filename}} | |
156 | ||
157 | Copy constructor. | |
158 | ||
159 | \func{}{wxFileName}{\param{const wxString\& }{fullpath}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
160 | ||
161 | Constructor taking a full filename. If it terminates with a '/', a directory path | |
162 | is constructed (the name will be empty), otherwise a file name and | |
163 | extension are extracted from it. | |
164 | ||
165 | \func{}{wxFileName}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
166 | ||

168 | ||
169 | \func{}{wxFileName}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
170 | ||
171 | Constructor from a directory name, base file name and extension. | |
172 | ||
173 | \func{}{wxFileName}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |

176 | ||
177 | ||
178 | \membersection{wxFileName::AppendDir}\label{wxfilenameappenddir} | |
179 | ||
180 | \func{void}{AppendDir}{\param{const wxString\& }{dir}} | |
181 | ||
182 | Appends a directory component to the path. This component should contain a | |
183 | single directory name level, i.e. not contain any path or volume separators nor | |
184 | should it be empty, otherwise the function does nothing (and generates an | |
185 | assert failure in debug build). | |
186 | ||
187 | ||
188 | \membersection{wxFileName::Assign}\label{wxfilenameassign} | |
189 | ||
190 | \func{void}{Assign}{\param{const wxFileName\& }{filepath}} | |

196 | \func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
197 | ||
198 | \func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
199 | ||
200 | Creates the file name from various combinations of data. | |
201 | ||
202 | ||
203 | \membersection{wxFileName::AssignCwd}\label{wxfilenameassigncwd} | |
204 | ||
205 | \func{static void}{AssignCwd}{\param{const wxString\& }{volume = wxEmptyString}} | |
206 | ||
207 | Makes this object refer to the current working directory on the specified | |
208 | volume (or current volume if {\it volume} is empty). | |
209 | ||
210 | \wxheading{See also} | |
211 | ||
212 | \helpref{GetCwd}{wxfilenamegetcwd} | |
213 | ||
214 | ||
215 | \membersection{wxFileName::AssignDir}\label{wxfilenameassigndir} | |
216 | ||
217 | \func{void}{AssignDir}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
218 | ||
219 | Sets this file name object to the given directory name. The name and extension | |
220 | will be empty. | |
221 | ||
222 | ||
223 | \membersection{wxFileName::AssignHomeDir}\label{wxfilenameassignhomedir} | |
224 | ||
225 | \func{void}{AssignHomeDir}{\void} | |
226 | ||
227 | Sets this file name object to the home directory. | |
228 | ||
229 | ||
230 | \membersection{wxFileName::AssignTempFileName}\label{wxfilenameassigntempfilename} | |
231 | ||
232 | \func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}} | |
233 | ||
234 | The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to | |
235 | create a temporary file and sets this object to the name of the file. If a | |
236 | temporary file couldn't be created, the object is put into the\rtfsp | |
237 | \helpref{invalid}{wxfilenameisok} state. | |
238 | ||
239 | ||
240 | \membersection{wxFileName::Clear}\label{wxfilenameclear} | |
241 | ||
242 | \func{void}{Clear}{\void} | |
243 | ||
244 | Reset all components to default, uninitialized state. | |
245 | ||
246 | ||
247 | \membersection{wxFileName::CreateTempFileName}\label{wxfilenamecreatetempfilename} | |
248 | ||
249 | \func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}} | |
250 | ||
251 | Returns a temporary file name starting with the given {\it prefix}. If | |
252 | the {\it prefix} is an absolute path, the temporary file is created in this | |
253 | directory, otherwise it is created in the default system directory for the | |
254 | temporary files or in the current directory. | |
255 | ||
256 | If the function succeeds, the temporary file is actually created. If\rtfsp | |
257 | {\it fileTemp} is not {\tt NULL}, this file will be opened using the name of | |
258 | the temporary file. When possible, this is done in an atomic way ensuring that | |
259 | no race condition occurs between the temporary file name generation and opening | |
260 | it which could often lead to security compromise on the multiuser systems. | |
261 | If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened. | |
262 | ||
263 | Under Unix, the temporary file will have read and write permissions for the | |
264 | owner only to minimize the security problems. | |
265 | ||
266 | \wxheading{Parameters} | |
267 | ||
268 | \docparam{prefix}{Prefix to use for the temporary file name construction} | |
269 | ||
270 | \docparam{fileTemp}{The file to open or {\tt NULL} to just get the name} | |
271 | ||
272 | \wxheading{Return value} | |
273 | ||
274 | The full temporary file name or an empty string on error. | |

287 | ||
288 | \func{static wxFileName}{DirName}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
289 | ||
290 | Returns the object corresponding to the directory with the given name. | |
291 | The {\it dir} parameter may have trailing path separator or not. | |
292 | ||
293 | ||
294 | ||

312 | ||
313 | Returns the file name object corresponding to the given {\it file}. This | |
314 | function exists mainly for symmetry with \helpref{DirName}{wxfilenamedirname}. | |

320 | \func{static wxString}{GetCwd}{\param{const wxString\& }{volume = ""}} | |
321 | ||
322 | Retrieves the value of the current working directory on the specified volume. If | |
323 | the volume is empty, the programs current working directory is returned for the | |
324 | current volume. | |
325 | ||
326 | \wxheading{Return value} | |

351 | ||
352 | \constfunc{wxString}{GetExt}{\void} | |

416 | ||
417 | Returns the path part of the filename (without the name or extension). The | |
418 | possible flags values are: | |
419 | ||
420 | \twocolwidtha{5cm} | |
421 | \begin{twocollist}\itemsep=0pt | |
422 | \twocolitem{{\bf wxPATH\_GET\_VOLUME}}{Return the path with the volume (does | |
423 | nothing for the filename formats without volumes), otherwise the path without | |
424 | volume part is returned.} | |
425 | \twocolitem{{\bf wxPATH\_GET\_SEPARATOR}}{Return the path with the trailing | |

433 | \func{static wxChar}{GetPathSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
434 | ||
435 | Returns the usually used path separator for this format. For all formats but | |
436 | {\tt wxPATH\_DOS} there is only one path separator anyhow, but for DOS there | |
437 | are two of them and the native one, i.e. the backslash is returned by this | |

446 | ||
447 | \func{static wxString}{GetPathSeparators}{\param{wxPathFormat }{format = wxPATH\_NATIVE}} | |
448 | ||
449 | Returns the string containing all the path separators for this format. For all | |
450 | formats but {\tt wxPATH\_DOS} this string contains only one character but for | |
451 | DOS and Windows both {\tt '/'} and {\tt '\textbackslash'} may be used as | |
452 | separators. | |

464 | ||
465 | ||
466 | \membersection{wxFileName::GetTimes}\label{wxfilenamegettimes} | |
467 | ||
468 | \constfunc{bool}{GetTimes}{\param{wxDateTime* }{dtAccess}, \param{wxDateTime* }{dtMod}, \param{wxDateTime* }{dtCreate}} | |
469 | ||
470 | Returns the last access, last modification and creation times. The last access | |
471 | time is updated whenever the file is read or written (or executed in the case | |
472 | of Windows), last modification time is only changed when the file is written | |
473 | to. Finally, the creation time is indeed the time when the file was created | |
474 | under Windows and the inode change time under Unix (as it is impossible to | |
475 | retrieve the real file creation time there anyhow) which can also be changed | |
476 | by many operations after the file creation. | |
477 | ||
478 | Any of the pointers may be {\tt NULL} if the corresponding time is not | |
479 | needed. | |
480 | ||
481 | \wxheading{Return value} | |
482 | ||
483 | {\tt true} on success, {\tt false} if we failed to retrieve the times. | |
