wxFileName Class Reference

#include <wx/filename.h>

Detailed Description

wxFileName encapsulates a file name.

This class serves two purposes: first, it provides the functions to split the file names into components and to recombine these components in the full file name which can then be passed to the OS file functions (and wxWidgets functions wrapping them). Second, it includes the functions for working with the files itself. Note that to change the file data you should use wxFile class instead. wxFileName provides functions for working with the file attributes.

When working with directory names (i.e. without filename and extension) make sure not to misuse the file name part of this class with the last directory. Instead initialize the wxFileName instance like this:

wxFileName dirname( "C:\mydir", "" );
MyMethod( dirname.GetPath() );

The same can be done using the static method wxFileName::DirName():

wxFileName dirname = wxFileName::DirName( "C:\mydir" );
MyMethod( dirname.GetPath() );

Accordingly, methods dealing with directories or directory names like wxFileName::IsDirReadable() use wxFileName::GetPath() whereas methods dealing with file names like wxFileName::IsFileReadable() use wxFileName::GetFullPath().

If it is not known whether a string contains a directory name or a complete file name (such as when interpreting user input) you need to use the static function wxFileName::DirExists() (or its identical variants wxDir::Exists() and wxDirExists()) and construct the wxFileName instance accordingly. This will only work if the directory actually exists, of course:

wxString user_input;
// get input from user

wxFileName fname;
if (wxDirExists(user_input))
    fname.AssignDir( user_input );
else
    fname.Assign( user_input );

Please note that many wxFileName methods accept the path format argument which is by 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.

File name format

wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS and VMS formats. 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 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 wxFileName::IsOk() returns false for it.

File names can be case-sensitive or not, the function wxFileName::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 wxFileName::IsAbsolute() or wxFileName::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 wxFileName::MakeAbsolute(). There is also an inverse function wxFileName::MakeRelativeTo() which undoes what wxFileName::Normalize(wxPATH_NORM_DOTS) does. Other functions returning information about the file format provided by this class are wxFileName::GetVolumeSeparator(), wxFileName::IsPathSeparator().

File name construction

You can initialize a wxFileName instance using one of the following functions:

• wxFileName::wxFileName()
• wxFileName::Assign()
• wxFileName::AssignCwd()
• wxFileName::AssignDir()
• wxFileName::AssignHomeDir()
• wxFileName::AssignTempFileName()
• wxFileName::DirName()
• wxFileName::FileName()
• wxFileName::operator=()

File name tests

Before doing other tests, you should use wxFileName::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 wxFileName::DirExists() can be used to test for directory existence. File names should be compared using the wxFileName::SameAs() method or wxFileName::operator==(). For testing basic access modes, you can use:

• wxFileName::IsDirWritable()
• wxFileName::IsDirReadable()
• wxFileName::IsFileWritable()
• wxFileName::IsFileReadable()
• wxFileName::IsFileExecutable()

File name components

These functions allow to examine and modify the individual directories of the path:

• wxFileName::AppendDir()
• wxFileName::InsertDir()
• wxFileName::GetDirCount()
• wxFileName::PrependDir()
• wxFileName::RemoveDir()
• wxFileName::RemoveLastDir()

To change the components of the file name individually you can use the following functions:

• wxFileName::GetExt()
• wxFileName::GetName()
• wxFileName::GetVolume()
• wxFileName::HasExt()
• wxFileName::HasName()
• wxFileName::HasVolume()
• wxFileName::SetExt()
• wxFileName::ClearExt()
• wxFileName::SetEmptyExt()
• wxFileName::SetName()
• wxFileName::SetVolume()

You can initialize a wxFileName instance using one of the following functions:

File name operations

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.

• wxFileName::GetModificationTime()
• wxFileName::GetTimes()
• wxFileName::SetTimes()
• wxFileName::Touch()

Other file system operations functions are:

• wxFileName::Mkdir()
• wxFileName::Rmdir()

Member Function Documentation

bool wxFileName::AppendDir

(

const wxString &

dir

)

Appends a directory component to the path.

This component should contain a single directory name level, i.e. not contain any path or volume separators nor should it be empty, otherwise the function does nothing and returns false (and generates an assert failure in debug build).

Notice that the return value is only available in wxWidgets 2.9.5 or later.

Sets this file name object to the given directory name.

The name and extension will be empty.

void wxFileName::AssignHomeDir

(

)

Sets this file name object to the home directory.

void wxFileName::AssignTempFileName

(

const wxString &

prefix

)

The function calls CreateTempFileName() to create a temporary file and sets this object to the name of the file.

If a temporary file couldn't be created, the object is put into an invalid state (see IsOk()).

void wxFileName::AssignTempFileName	(	const wxString &	prefix,
		wxFile *	fileTemp
	)

The function calls CreateTempFileName() to create a temporary file name and open fileTemp with it.

If the file couldn't be opened, the object is put into an invalid state (see IsOk()).

void wxFileName::AssignTempFileName	(	const wxString &	prefix,
		wxFFile *	fileTemp
	)

The function calls CreateTempFileName() to create a temporary file name and open fileTemp with it.

If the file couldn't be opened, the object is put into an invalid state (see IsOk()).

void wxFileName::Clear

(

)

Reset all components to default, uninitialized state.

void wxFileName::ClearExt

(

)

Removes the extension from the file name resulting in a file name with no trailing dot.

See Also

SetExt(), SetEmptyExt()

static wxString wxFileName::CreateTempFileName ( const wxString &  prefix, wxFile *  fileTemp = NULL  )

static

Returns a temporary file name starting with the given prefix.

If prefix is an absolute path and ends in a separator, the temporary file is created in this directory; if it is an absolute filepath or there is no separator, the temporary file is created in its path, with the 'name' segment prepended to the temporary filename; otherwise it is created in the default system directory for temporary files or in the current directory.

If the function succeeds, the temporary file is actually created. If fileTemp is not NULL, this wxFile will be opened using the name of the temporary file. Where possible this is done in an atomic way to ensure that no race condition occurs between creating the temporary file name and opening it, which might lead to a security compromise on multiuser systems. If fileTemp is NULL, the file is created but not opened. Under Unix, the temporary file will have read and write permissions for the owner only, to minimize security problems.

Parameters

prefix	Location to use for the temporary file name construction. If prefix is a directory it must have a terminal separator
fileTemp	The file to open, or NULL just to get the name

Returns

The full temporary filepath, or an empty string on error.

static wxString wxFileName::CreateTempFileName ( const wxString &  prefix, wxFFile *  fileTemp = NULL  )

static

This is the same as CreateTempFileName(const wxString &prefix, wxFile *fileTemp) but takes a wxFFile parameter instead of wxFile.

bool wxFileName::DirExists

(

)

const

Returns true if the directory with this name exists.

Notice that this function tests the directory part of this object, i.e. the string returned by GetPath(), and not the full path returned by GetFullPath().

See Also

FileExists(), Exists()

static bool wxFileName::DirExists ( const wxString &  dir )

static

Returns true if the directory with name dir exists.

See Also

FileExists(), Exists()

static wxFileName wxFileName::DirName ( const wxString &  dir, wxPathFormat  format = wxPATH_NATIVE  )

static

Returns the object corresponding to the directory with the given name.

The dir parameter may have trailing path separator or not.

void wxFileName::DontFollowLink

(

)

Turns off symlink dereferencing.

By default, all operations in this class work on the target of a symbolic link (symlink) if the path of the file is actually a symlink. Using this method allows to turn off this "symlink following" behaviour and apply the operations to this path itself, even if it is a symlink.

The following methods are currently affected by this option:

• GetTimes() (but not SetTimes() as there is no portable way to change the time of symlink itself).
• Existence checks: FileExists(), DirExists() and Exists() (notice that static versions of these methods always follow symlinks).
• IsSameAs().

See Also

ShouldFollowLink()

Since

2.9.5

bool wxFileName::Exists

(

int

flags = wxFILE_EXISTS_ANY

)

const

Calls the static overload of this function with the full path of this object.

Since

2.9.4 (flags is new since 2.9.5)

static bool wxFileName::Exists ( const wxString &  path, int  flags = wxFILE_EXISTS_ANY  )

static

Returns true if either a file or a directory or something else with this name exists in the file system.

Don't dereference path if it is a symbolic link and flags argument contains wxFILE_EXISTS_NO_FOLLOW.

This method is equivalent to

FileExists() || DirExists() 

under Windows, but under Unix it also returns true if the file identifies a special file system object such as a device, a socket or a FIFO.

Alternatively you may check for the existence of a file system entry of a specific type by passing the appropriate flags (this parameter is new since wxWidgets 2.9.5). E.g. to test for a symbolic link existence you could use wxFILE_EXISTS_SYMLINK.

2.9.4

static wxFileName wxFileName::FileName ( const wxString &  file, wxPathFormat  format = wxPATH_NATIVE  )

static

Returns the file name object corresponding to the given file.

This function exists mainly for symmetry with DirName().

static wxString wxFileName::GetCwd ( const wxString &  volume = wxEmptyString )

static

Retrieves the value of the current working directory on the specified volume.

If the volume is empty, the program's current working directory is returned for the current volume.

Returns

The string containing the current working directory or an empty string on error.

Returns the file name extension.

static wxString wxFileName::GetForbiddenChars ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the characters that can't be used in filenames and directory names for the specified format.

static wxPathFormat wxFileName::GetFormat ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the canonical path format for this platform.

wxString wxFileName::GetHumanReadableSize	(	const wxString &	failmsg = _("Not available"),
		int	precision = 1,
		wxSizeConvention	conv = wxSIZE_CONV_TRADITIONAL
	)		const

Returns the representation of the file size in a human-readable form.

In the first version, the size of this file is used. In the second one, the specified size bytes is used.

If the file size could not be retrieved or bytes is wxInvalidSize or zero, the failmsg string is returned.

Otherwise the returned string is a floating-point number with precision decimal digits followed by the abbreviation of the unit used. By default the traditional, although incorrect, convention of using SI units for multiples of 1024 is used, i.e. returned string will use suffixes of B, KB, MB, GB, TB for bytes, kilobytes, megabytes, gigabytes and terabytes respectively. With the IEC convention the names of the units are changed to B, KiB, MiB, GiB and TiB for bytes, kibibytes, mebibytes, gibibytes and tebibytes. Finally, with SI convention the same B, KB, MB, GB and TB suffixes are used but in their correct SI meaning, i.e. as multiples of 1000 and not 1024.

Support for the different size conventions is new in wxWidgets 2.9.1, in previous versions only the traditional convention was implemented.

static wxString wxFileName::GetHumanReadableSize ( const wxULongLong &  bytes, const wxString &  nullsize = _("Not available"), int  precision = 1, wxSizeConvention  conv = wxSIZE_CONV_TRADITIONAL  )

GetFullName()

wxString wxFileName::GetPath	(	int	flags = wxPATH_GET_VOLUME,
		wxPathFormat	format = wxPATH_NATIVE
	)		const

Returns the path part of the filename (without the name or extension).

The possible flags values are:

• wxPATH_GET_VOLUME: Return the path with the volume (does nothing for the filename formats without volumes), otherwise the path without volume part is returned.

• wxPATH_GET_SEPARATOR: Return the path with the trailing separator, if this flag is not given there will be no separator at the end of the path.

• wxPATH_NO_SEPARATOR: Don't include the trailing separator in the returned string. This is the default (the value of this flag is 0) and exists only for symmetry with wxPATH_GET_SEPARATOR.

Note

If the path is a toplevel one (e.g. "/" on Unix or "C:\" on Windows), then the returned path will contain trailing separator even with wxPATH_NO_SEPARATOR.

static wxUniChar wxFileName::GetPathSeparator ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the usually used path separator for this format.

For all formats but wxPATH_DOS there is only one path separator anyhow, but for DOS there are two of them and the native one, i.e. the backslash is returned by this method.

See Also

GetPathSeparators()

static wxString wxFileName::GetPathSeparators ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the string containing all the path separators for this format.

For all formats but wxPATH_DOS this string contains only one character but for DOS and Windows both '/' and '\' may be used as separators.

See Also

GetPathSeparator()

static wxString wxFileName::GetPathTerminators ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the string of characters which may terminate the path part.

This is the same as GetPathSeparators() except for VMS path format where ] is used at the end of the path part.

wxString wxFileName::GetPathWithSep

(

wxPathFormat

format = wxPATH_NATIVE

)

const

Returns the path with the trailing separator, useful for appending the name to the given path.

This is the same as calling

GetPath(wxPATH_GET_VOLUME | wxPATH_GET_SEPARATOR, format)

wxString wxFileName::GetShortPath

(

)

const

Return the short form of the path (returns identity on non-Windows platforms).

wxULongLong wxFileName::GetSize

(

)

const

Returns the size of the file If the file does not exist or its size could not be read (because e.g.

the file is locked by another process) the returned value is wxInvalidSize.

static wxULongLong wxFileName::GetSize ( const wxString &  filename )

static

Returns the size of the file If the file does not exist or its size could not be read (because e.g.

the file is locked by another process) the returned value is wxInvalidSize.

static wxString wxFileName::GetTempDir ( )

static

Returns the directory used for temporary files.

bool wxFileName::GetTimes	(	wxDateTime *	dtAccess,
		wxDateTime *	dtMod,
		wxDateTime *	dtCreate
	)		const

Returns the last access, last modification and creation times.

The last access time is updated whenever the file is read or written (or executed in the case of Windows), last modification time is only changed when the file is written to. Finally, the creation time is indeed the time when the file was created under Windows and the inode change time under Unix (as it is impossible to retrieve the real file creation time there anyhow) which can also be changed by many operations after the file creation.

If no filename or extension is specified in this instance of wxFileName (and therefore IsDir() returns true) then this function will return the directory times of the path specified by GetPath(), otherwise the file times of the file specified by GetFullPath(). Any of the pointers may be NULL if the corresponding time is not needed.

Returns

true on success, false if we failed to retrieve the times.

wxString wxFileName::GetVolume

(

)

const

Returns the string containing the volume for this file name, empty if it doesn't have one or if the file system doesn't support volumes at all (for example, Unix).

static wxString wxFileName::GetVolumeSeparator ( wxPathFormat  format = wxPATH_NATIVE )

static

Returns the string separating the volume from the path for this format.

static wxString wxFileName::GetVolumeString ( char  drive, int  flags = wxPATH_GET_SEPARATOR  )

This function builds a volume path string, for example "C:\\".

Implemented for the platforms which use drive letters, i.e. DOS, MSW and OS/2 only.

Since

2.9.0

Parameters

drive	The drive letter, 'A' through 'Z' or 'a' through 'z'.

bool wxFileName::InsertDir	(	size_t	before,
		const wxString &	dir
	)

Inserts a directory component before the zero-based position in the directory list.

As with AppendDir(), dir must be a single directory name and the function returns false and does nothing else if it isn't.

bool wxFileName::IsAbsolute

(

wxPathFormat

format = wxPATH_NATIVE

)

const

bool wxFileName::IsDir

(

)

const

Returns true if this object represents a directory, false otherwise (i.e.

if it is a file).

Note that this method doesn't test whether the directory or file really exists, you should use DirExists() or FileExists() for this.

bool wxFileName::IsDirReadable

(

)

const

Returns true if the directory component of this instance is an existing directory and this process has read permissions on it.

Read permissions on a directory mean that you can list the directory contents but it doesn't imply that you have read permissions on the files contained.

static bool wxFileName::IsDirReadable ( const wxString &  dir )

static

Returns true if the given dir is an existing directory and this process has read permissions on it.

Read permissions on a directory mean that you can list the directory contents but it doesn't imply that you have read permissions on the files contained.

static bool wxFileName::IsMSWUniqueVolumeNamePath ( const wxString &  path, wxPathFormat  format = wxPATH_NATIVE  )

static

Returns true if the volume part of the path is a unique volume name.

This function will always return false if the path format is not wxPATH_DOS.

Unique volume names are Windows volume identifiers which remain the same regardless of where the volume is actually mounted. Example of a path using a volume name could be

\\?\Volume{8089d7d7-d0ac-11db-9dd0-806d6172696f}\Program Files\setup.exe

Since

2.9.1

bool wxFileName::IsOk

(

)

const

Returns true if the filename is valid, false if it is not initialized yet.

The assignment functions and Clear() may reset the object to the uninitialized, invalid state (the former only do it on failure).

static bool wxFileName::IsPathSeparator ( wxChar  ch, wxPathFormat  format = wxPATH_NATIVE  )

static

Returns true if the char is a path separator for this format.

bool wxFileName::IsRelative

(

wxPathFormat

wxFileName::Normalize(wxPATH_NORM_DOTS | wxPATH_NORM_ABSOLUTE |
                      wxPATH_NORM_TILDE, cwd, format)

See Also

MakeRelativeTo(), Normalize(), IsAbsolute()

bool wxFileName::MakeRelativeTo	(	const wxString &	pathBase = wxEmptyString,
		wxPathFormat	format = wxPATH_NATIVE
	)

This function tries to put this file name in a form relative to pathBase.

In other words, it returns the file name which should be used to access this file if the current directory were pathBase.

Parameters

pathBase	The directory to use as root, current directory is used by default
format	The file name format, native by default

Returns

true if the file name has been changed, false if we failed to do anything with it (currently this only happens if the file name is on a volume different from the volume specified by pathBase).

Normalize()

bool wxFileName::Mkdir	(	int	perm = wxS_DIR_DEFAULT,
		int	flags = 0
	)		const

Creates a directory.

Parameters

perm	The permissions for the newly created directory. See the wxPosixPermissions enumeration for more info.
flags	If the flags contain wxPATH_MKDIR_FULL flag, try to create each directory in the path and also don't return an error if the target directory already exists.

Returns

Returns true if the directory was successfully created, false otherwise.

static bool wxFileName::Mkdir ( const wxString &  dir, int  perm = wxS_DIR_DEFAULT, int  flags = 0  )

static

Creates a directory.

Parameters

dir	The directory to create
perm	The permissions for the newly created directory. See the wxPosixPermissions enumeration for more info.
flags	If the flags contain wxPATH_MKDIR_FULL flag, try to create each directory in the path and also don't return an error if the target directory already exists.

Returns

Returns true if the directory was successfully created, false otherwise.

bool wxFileName::Normalize	(	int	flags = wxPATH_NORM_ALL,
		const wxString &	cwd = wxEmptyString,
		wxPathFormat	format = wxPATH_NATIVE
	)

Normalize the path.

With the default flags value, the path will be made absolute, without any ".." and "." and all environment variables will be expanded in it.

Notice that in some rare cases normalizing a valid path may result in an invalid wxFileName object. E.g. normalizing "./" path using wxPATH_NORM_DOTS but not wxPATH_NORM_ABSOLUTE will result in a completely empty and thus invalid object. As long as there is a non empty file name the result of normalization will be valid however.

Parameters

flags	The kind of normalization to do with the file name. It can be any or-combination of the wxPathNormalize enumeration values.
cwd	If not empty, this directory will be used instead of current working directory in normalization (see wxPATH_NORM_ABSOLUTE).
format	The file name format to use when processing the paths, native by default.

Returns

true if normalization was successfully or false otherwise.

bool wxFileName::operator!=

(

const wxFileName &

Assigns the new value to this filename object.

wxFileName& wxFileName::operator=

(

const wxString &

filename

)

Assigns the new value to this filename object.

bool wxFileName::ReplaceEnvVariable	(	const wxString &	envname,
		const wxString &	replacementFmtString = "$%s",
		wxPathFormat	format = wxPATH_NATIVE
	)

If the path contains the value of the environment variable named envname then this function replaces it with the string obtained from wxString::Format(replacementFmtString, value_of_envname_variable).

This function is useful to make the path shorter or to make it dependent from a certain environment variable. Normalize() with wxPATH_NORM_ENV_VARS can perform the opposite of this function (depending on the value of replacementFmtString).

The name and extension of this filename are not modified.

Example:

wxFileName fn("/usr/openwin/lib/someFile");
fn.ReplaceEnvVariable("OPENWINHOME");
        // now fn.GetFullPath() == "$OPENWINHOME/lib/someFile"

Since

2.9.0

Returns

true if the operation was successful (which doesn't mean that something was actually replaced, just that wxGetEnv didn't fail).

bool wxFileName::ReplaceHomeDir

(

wxPathFormat

format = wxPATH_NATIVE

)

Replaces, if present in the path, the home directory for the given user (see wxGetHomeDir) with a tilde (~).

Normalize() with wxPATH_NORM_TILDE performs the opposite of this function.

The name and extension of this filename are not modified.

Since

2.9.0

Returns

true if the operation was successful (which doesn't mean that something was actually replaced, just that wxGetHomeDir didn't fail).

bool wxFileName::Rmdir

(

int

flags = 0

)

const

Deletes the specified directory from the file system.

Parameters

flags

Can contain one of wxPATH_RMDIR_FULL or wxPATH_RMDIR_RECURSIVE. By default contains neither so the directory will not be removed unless it is empty.

Returns

Returns true if the directory was successfully deleted, false otherwise.

static bool wxFileName::Rmdir ( const wxString &  dir, int  flags = 0  )

static

Deletes the specified directory from the file system.

Parameters

dir	The directory to delete
flags	Can contain one of wxPATH_RMDIR_FULL or wxPATH_RMDIR_RECURSIVE. By default contains neither so the directory will not be removed unless it is empty.

static bool wxFileName::SetCwd ( const wxString &  cwd )

static

Changes the current working directory.

void wxFileName::SetEmptyExt

(

)

Sets the extension of the file name to be an empty extension.

See Also

SetExt(), ClearExt()

void wxFileName::SetExt

(

const wxString &

ext

)

Sets the extension of the file name.

Setting an empty string as the extension will remove the extension resulting in a file name without a trailing dot, unlike a call to SetEmptyExt().

See Also

SetEmptyExt(), ClearExt()

void wxFileName::SetFullName

(

const wxString &

fullname

)

The full name is the file name and extension (but without the path).

void wxFileName::SetName

(

const wxString &

name

)

Sets the name part (without extension).

See Also

SetFullName()

void wxFileName::SetPath	(	const wxString &	path,
		wxPathFormat	format = wxPATH_NATIVE
	)

Sets the path.

The path argument includes both the path and the volume, if supported by format.

Calling this function doesn't affect the name and extension components, to change them as well you can use Assign() or just an assignment operator.

See Also

GetPath()

bool wxFileName::SetPermissions

(

int

permissions

)

Sets permissions for this file or directory.

Parameters

permissions

The new permissions: this should be a combination of wxPosixPermissions enum elements.

Since

3.0

Note

If this is a symbolic link and it should not be followed this call will fail.

Returns

		const wxDateTime *	dtMod,
		const wxDateTime *	dtCreate
	)		const

Sets the file creation and last access/modification times (any of the pointers may be NULL).

Notice that the file creation time can't be changed under Unix, so dtCreate is ignored there (but true is still returned). Under Windows all three times can be set.

void wxFileName::SetVolume

(

const wxString &

volume

)

Sets the volume specifier.

bool wxFileName::ShouldFollowLink

(

)

const

Return whether some operations will follow symlink.

By default, file operations "follow symlink", i.e. operate on its target and not on the symlink itself. See DontFollowLink() for more information.

Since

2.9.5

static void wxFileName::SplitPath ( const wxString &  fullpath, wxString *  volume, wxString *  path, wxString *  name, wxString *  ext, bool *  hasExt = NULL, wxPathFormat  format = wxPATH_NATIVE  )

static

This function splits a full file name into components: the volume (with the first version) path (including the volume in the second version), the base name and the extension.

Any of the output parameters (volume, path, name or ext) may be NULL if you are not interested in the value of a particular component. Also, fullpath may be empty on entry. On return, path contains the file path (without the trailing separator), name contains the file name and ext contains the file extension without leading dot. All three of them may be empty if the corresponding component is. The old contents of the strings pointed to by these parameters will be overwritten in any case (if the pointers are not NULL).

Note that for a filename "foo." the extension is present, as indicated by the trailing dot, but empty. If you need to cope with such cases, you should use hasExt instead of relying on testing whether ext is empty or not.

static void wxFileName::SplitPath ( const wxString &  fullpath, wxString *  volume, wxString *  path, wxString *  name, wxString *  ext, wxPathFormat  format  )

static

This function splits a full file name into components: the volume (with the first version) path (including the volume in the second version), the base name and the extension.

Any of the output parameters (volume, path, name or ext) may be NULL if you are not interested in the value of a particular component. Also, fullpath may be empty on entry. On return, path contains the file path (without the trailing separator), name contains the file name and ext contains the file extension without leading dot. All three of them may be empty if the corresponding component is. The old contents of the strings pointed to by these parameters will be overwritten in any case (if the pointers are not NULL).

Note that for a filename "foo." the extension is present, as indicated by the trailing dot, but empty. If you need to cope with such cases, you should use hasExt instead of relying on testing whether ext is empty or not.

static void wxFileName::SplitPath ( const wxString &  fullpath, wxString *  path, wxString *  name, wxString *  ext, wxPathFormat  format = wxPATH_NATIVE  )

static

This function splits a full file name into components: the volume (with the first version) path (including the volume in the second version), the base name and the extension.

Any of the output parameters (volume, path, name or ext) may be NULL if you are not interested in the value of a particular component. Also, fullpath may be empty on entry. On return, path contains the file path (without the trailing separator), name contains the file name and ext contains the file extension without leading dot.

Note that for a filename "foo." the extension is present, as indicated by the trailing dot, but empty. If you need to cope with such cases, you should use hasExt instead of relying on testing whether ext is empty or not.

static void wxFileName::SplitVolume ( const wxString &  fullpath, wxString *  volume, wxString *  path, wxPathFormat  format = wxPATH_NATIVE  )

static

Splits the given fullpath into the volume part (which may be empty) and the pure path part, not containing any volume.

See Also

SplitPath()

static wxString wxFileName::StripExtension ( const wxString &  fullname )

static

Strip the file extension.

This function does more than just removing everything after the last period from the string, for example it will return the string ".vimrc" unchanged because the part after the period is not an extension but the file name in this case. You can use wxString::BeforeLast() to really get just the part before the last period (but notice that that function returns empty string if period is not present at all unlike this function which returns the fullname unchanged in this case).

Parameters

fullname

File path including name and, optionally, extension.

Returns

File path without extension
