Glib::RefPtr< Gio::Filewrap (GFile* object, bool take_copy=false)
 A Glib::wrap() method for this object.

Detailed Description

File and directory handling.

Gio::File is a high level abstraction for manipulating files on a virtual file system. Gio::Files are lightweight, immutable objects that do no I/O upon creation. It is necessary to understand that a Gio::File object does not represent a file, merely a handle to a file. All file I/O is implemented as streaming operations (see Gio::InputStream and Gio::OutputStream).

A GioFile can be constructed from a path, URI, or a command line argument.

You can move through the filesystem with Gio::File handles with get_parent() to get a handle to the parent directory, get_child() to get a handle to a child within a directory, and resolve_relative_path() to resolve a relative path between two Gio::Files.

Many Gio::File operations have both synchronous and asynchronous versions to suit your application. Asynchronous versions of synchronous functions simply have _async() appended to their function names. The asynchronous I/O functions call a SlotAsyncReady callback slot which is then used to finalize the operation, producing a AsyncResult which is then passed to the function's matching _finish() operation.

Some Gio::File operations do not have synchronous analogs, as they may take a very long time to finish, and blocking may leave an application unusable. Notable cases include: mount_mountable() to mount a mountable file, unmount_mountable() to unmount a mountable file, and eject_mountable() to eject a mountable file.

One notable feature of Gio::Files are entity tags, or "etags" for short. Entity tags are somewhat like a more abstract version of the traditional mtime, and can be used to quickly determine if the file has been modified from the version on the file system. See the HTTP 1.1 specification for HTTP Etag headers, which are a very similar concept.

Since glibmm 2.16:

Member Typedef Documentation

typedef sigc::slot<void, goffset, goffset> Gio::File::SlotFileProgress

A signal handler would be, for instance: void on_file_progress(goffset current_num_bytes, goffset total_num_bytes);.

typedef sigc::slot<bool, const char*, goffset> Gio::File::SlotReadMore

A signal handler would be, for instance: bool on_read_more(const char* file_contents, goffset file_size);.

static void Gio::File::add_interface ( GType  gtype_implementer  )  [static]
Glib::RefPtr<FileOutputStream> Gio::File::append_to ( FileCreateFlags  flags = FILE_CREATE_NONE  ) 

Gets an output stream for appending data to the file.

If the file doesn't already exist it is created.

By default files created are generally readable by everyone, but if you pass FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

Some filesystems don't allow all filenames, and may throw a Gio::Error with INVALID_FILENAME. If the file is a directory a Gio::Error with IS_DIRECTORY will be thrown. Other errors are possible too, and depend on what kind of filesystem the file is on.

Parameters:
flags A set of FileCreateFlags.
Returns:
A FileOutputStream.
Glib::RefPtr<FileOutputStream> Gio::File::append_to ( const Glib::RefPtr< Cancellable >&  cancellable,
FileCreateFlags  flags = FILE_CREATE_NONE 
)

Gets an output stream for appending data to the file.

If the file doesn't already exist it is created.

By default files created are generally readable by everyone, but if you pass FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

Some filesystems don't allow all filenames, and may throw a Gio::Error with INVALID_FILENAME. If the file is a directory a Gio::Error with IS_DIRECTORY will be thrown. Other errors are possible too, and depend on what kind of filesystem the file is on.

Parameters:
flags A set of FileCreateFlags.
cancellable Optional Cancellable object.
Returns:
A FileOutputStream.
void Gio::File::append_to_async ( const SlotAsyncReady slot,
FileCreateFlags  flags = FILE_CREATE_NONE,
int  io_priority = Glib::PRIORITY_DEFAULT 
)

Asynchronously opens the file for appending.

For more details, see append_to() which is the synchronous version of this call.

When the operation is finished, slot will be called. You can then call append_to_finish() to get the result of the operation.

Parameters:
slot A callback slot which will be called when the request is satisfied.
flags a set of FileCreateFlags.
io_priority The I/O priority of the request.
void Gio::File::append_to_async ( const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable,
FileCreateFlags  flags = FILE_CREATE_NONE,
int  io_priority = Glib::PRIORITY_DEFAULT 
)

Asynchronously opens the file for appending.

For more details, see append_to() which is the synchronous version of this call.

When the operation is finished, slot will be called. You can then call append_to_finish() to get the result of the operation.

Parameters:
slot A callback slot which will be called when the request is satisfied.
cancellable A Cancellable object which can be used to cancel the operation.
flags a set of FileCreateFlags.
io_priority The I/O priority of the request.
Glib::RefPtr<FileOutputStream> Gio::File::append_to_finish ( const Glib::RefPtr< AsyncResult >&  result  ) 

Finishes an asynchronous file append operation started with g_file_append_to_async().

Parameters:
res AsyncResult.
Returns:
A valid FileOutputStream or 0 on error. Free the returned object with Glib::object_unref().
bool Gio::File::copy ( const Glib::RefPtr< File >&  destination,
FileCopyFlags  flags = FILE_COPY_NONE 
)
bool Gio::File::copy ( const Glib::RefPtr< File >&  destination,
const SlotFileProgress slot,
FileCopyFlags  flags = FILE_COPY_NONE 
)
bool Gio::File::copy ( const Glib::RefPtr< File >&  destination,
const SlotFileProgress slot,
const Glib::RefPtr< Cancellable >&  cancellable,
FileCopyFlags  flags = FILE_COPY_NONE 
)

Copies the file source to the location specified by destination.

Can not handle recursive copies of directories. If the flag FILE_COPY_OVERWRITE is specified an already existing destination file is overwritten. If the flag FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks will be copied as symlinks, otherwise the target of the source symlink will be copied.

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

The operation can be monitored via the slot callback.

If the source file does not exist then a Gio::Error with NOT_FOUND will be thrown, independent on the status of the destination.

If FILE_COPY_OVERWRITE is not specified and the target exists, then a Gio::Error with EXISTS will be thrown.

If trying to overwrite a file over a directory a Gio::Error with IS_DIRECTORY will be thrown. If trying to overwrite a directory with a directory a Gio::Error with WOULD_MERGE will be thrown.

If the source is a directory and the target does not exist, or FILE_COPY_OVERWRITE is specified and the target is a file, then a Gio::Error with WOULD_RECURSE will be thrown.

If you are interested in copying the Gio::File object itself (not the on-disk file), see File::dup().

Gets the base name (the last component of the path) for a given File.

If called for the top level of a system (such as the filesystem root or a uri like sftp://host/) it will return a single directory separator (and on Windows, possibly a drive letter).

The base name is a byte string (*not* UTF-8). It has no defined encoding or rules other than it may not contain zero bytes. If you want to use filenames in a user interface you should use the display name that you can get by requesting the FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info().

This call does no blocking i/o.

Returns:
String containing the File's base name, or 0 if given File is invalid. The returned string should be freed with Glib::free() when no longer needed.

This call does no blocking i/o.

Parameters:
display_name String to a possible child.
Returns:
A File to the specified child, or 0 if the display name couldn't be converted. Free the returned object with Glib::object_unref().
Glib::RefPtr<File> Gio::File::get_parent (  )  const

A File structure to the parent of the given File or 0 if there is no parent. Free the returned object with Glib::object_unref().
Glib::ustring Gio::File::get_parse_name (  )  const

Gets the parse name of the file.

A parse name is a UTF-8 string that describes the file such that one can get the File back using g_file_parse_name().

This is generally used to show the File as a nice full-pathname kind of string in a user interface, like in a location entry.

For local files with names that can safely be converted to UTF8 the pathname is used, otherwise the IRI is used (a form of URI that allows UTF8 characters unescaped).

This call does no blocking i/o.

Returns:
A string containing the File's parse name. The returned string should be freed with Glib::free() when no longer needed.
std::string Gio::File::get_path (  )  const

Gets the local pathname for File, if one exists.

This call does no blocking i/o.

Returns:
String containing the File's path, or 0 if no such path exists. The returned string should be freed with Glib::free() when no longer needed.
std::string Gio::File::get_relative_path ( const Glib::RefPtr< const File >&  descendant  )  const

Gets the path for descendant relative to parent.

This call does no blocking i/o.

Parameters:
descendant Input File.
Returns:
String with the relative path from descendant to parent, or 0 if descendant doesn't have parent as prefix. The returned string should be freed with Glib::free() when no longer needed.
std::string Gio::File::get_uri (  )  const

Gets the URI for the file.

This call does no blocking i/o.

Returns:
A string containing the File's URI. The returned string should be freed with Glib::free() when no longer needed.
std::string Gio::File::get_uri_scheme (  )  const

Gets the URI scheme for a File.

RFC 3986 decodes the scheme as: <programlisting> URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ] </programlisting> Common schemes include "file", "http", "ftp", etc.

This call does no blocking i/o.

Returns:
A string containing the URI scheme for the given File. The returned string should be freed with Glib::free() when no longer needed.

Returns:
true if the file is a child of any parent.
bool Gio::File::has_parent ( const Glib::RefPtr< File >&  parent  )  const

Checks if file has a parent, and optionally, if it is parent.

If parent is 0 then this function returns true if file has any parent at all. If parent is non-0 then true is only returned if file is a child of parent.

Since glibmm 2.24:
Parameters:
parent The parent to check for, or 0.
Returns:
true if file is a child of parent (or any parent in the case that parent is 0).
bool Gio::File::has_prefix ( const Glib::RefPtr< const File >&  prefix  )  const

Checks whether file has the prefix specified by prefix.

In other word, if the names of inital elements of files pathname match prefix. Only full pathname elements are matched, so a path like /foo is not considered a prefix of /foobar, only of /foo/bar.

This call does no i/o, as it works purely on names. As such it can sometimes return false even if file is inside a prefix (from a filesystem point of view), because the prefix of file is an alias of prefix.

Parameters:
prefix Input File.
Returns:
true if the files's parent, grandparent, etc is prefix. false otherwise.
bool Gio::File::has_uri_scheme ( const std::string uri_scheme  )  const

Checks to see if a File has a given URI scheme.

This call does no blocking i/o.

Parameters:
uri_scheme A string containing a URI scheme.
Returns:
true if File's backend supports the given URI scheme, false if URI scheme is 0, not supported, or File is invalid.
guint Gio::File::hash (  )  const

Creates a hash value for a File.

This call does no blocking i/o.

Parameters:
file gconstpointer to a File.
Returns:
0 if file is not a valid File, otherwise an integer that can be used as hash value for the File. This function is intended for easily hashing a File to add to a HashTable or similar data structure.
bool Gio::File::is_native (  )  const

Checks to see if a file is native to the platform.

A native file s one expressed in the platform-native filename format, e.g. "C:\Windows" or "/usr/bin/". This does not mean the file is local, as it might be on a locally mounted remote filesystem.

On some systems non-native files may be available using the native filesystem via a userspace filesystem (FUSE), in these cases this call will return false, but g_file_get_path() will still return a native path.

This call does no blocking i/o.

Returns:
true if file is native.

void Gio::File::mount_mountable ( const SlotAsyncReady slot,
MountMountFlags  flags = MOUNT_MOUNT_NONE 
)

Mounts a file of type FILE_TYPE_MOUNTABLE without user interaction.

When the operation is finished, slot will be called. You can then call mount_mountable_finish() to get the result of the operation.

Parameters:
slot A callback slot which will be called when the request is satisfied.

void Gio::File::mount_mountable ( const Glib::RefPtr< MountOperation >&  mount_operation,
const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable,
MountMountFlags  flags = MOUNT_MOUNT_NONE 
)

Mounts a file of type FILE_TYPE_MOUNTABLE.

Using mount_operation, you can request callbacks when, for instance, passwords are needed during authentication.

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

When the operation is finished, slot will be called. You can then call mount_mountable_finish() to get the result of the operation.

Glib::RefPtr<File> Gio::File::mount_mountable_finish ( const Glib::RefPtr< AsyncResult >&  result  ) 

Finishes a mount operation.

See g_file_mount_mountable() for details.

Finish an asynchronous mount operation that was started with g_file_mount_mountable().

Parameters:
result A AsyncResult.
Returns:
A File or 0 on error. Free the returned object with Glib::object_unref().
bool Gio::File::move ( const Glib::RefPtr< File >&  destination,
FileCopyFlags  flags = FILE_COPY_NONE 
)
bool Gio::File::move ( const Glib::RefPtr< File >&  destination,
const SlotFileProgress slot,
FileCopyFlags  flags = FILE_COPY_NONE 
)
bool Gio::File::move ( const Glib::RefPtr< File >&  destination,
const SlotFileProgress slot,
const Glib::RefPtr< Cancellable >&  cancellable,
FileCopyFlags  flags = FILE_COPY_NONE 
)

Tries to move the file or directory source to the location specified by destination.

If native move operations are supported then this is used, otherwise a copy and delete fallback is used. The native implementation may support moving directories (for instance on moves inside the same filesystem), but the fallback code does not.

If the flag FILE_COPY_OVERWRITE is specified an already existing destination file is overwritten.

If the flag FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks will be copied as symlinks, otherwise the target of the source symlink will be copied.

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

The operation can be monitored via the slot callback. If the source file does not exist then a Gio::Error with NOT_FOUND will be thrown, independent on the status of the destination.

If G_FILE_COPY_OVERWRITE is not specified and the target exists, then a Gio::Error with EXISTS will be thrown.

If trying to overwrite a file over a directory a Gio::Error with IS_DIRECTORY will be thrown. If trying to overwrite a directory with a directory a Gio::Error with WOULD_MERGE will be thrown.

If the source is a directory and the target does not exist, or FILE_COPY_OVERWRITE is specified and the target is a file, then a Gio::Error with WOULD_RECURSE may be thrown (if the native move operation isn't available).

Glib::RefPtr<FileIOStream> Gio::File::open_readwrite ( const Glib::RefPtr< Cancellable >&  cancellable  ) 

Opens an existing file for reading and writing.

The result is a FileIOStream that can be used to read and write the contents of the file.

If cancellable is not 0, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IO_ERROR_CANCELLED will be returned.

If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. If the file is a directory, the G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on. Note that in many non-local file cases read and write streams are not supported, so make sure you really need to do read and write streaming, rather than just opening for reading or writing.

Since glibmm 2.22:
Parameters:
cancellable A Cancellable.

bool Gio::File::query_exists (  )  const

Utility function to check if a particular file exists.

This is implemented using query_info() and as such does blocking I/O.

Note that in many cases it is racy to first check for file existance and then execute something based on the outcome of that, because the file might have been created or removed inbetween the operations. The general approach to handling that is to not check, but just do the operation and handle the errors as they come.

As an example of race-free checking, take the case of reading a file, and if it doesn't exist, creating it. There are two racy versions: read it, and on error create it; and: check if it exists, if not create it. These can both result in two processes creating the file (with perhaps a partially written file as the result). The correct approach is to always try to create the file with g_file_create() which will either atomically create the file or throw a Gio::Error with EXISTS.

However, in many cases an existance check is useful in a user interface, for instance to make a menu item sensitive/insensitive, so that you don't have to fool users that something is possible and then just show and error dialog. If you do this, you should make sure to also handle the errors that can happen due to races when you execute the operation.

Returns:
true if the file exists (and can be detected without error), false otherwise (or if cancelled).
bool Gio::File::query_exists ( const Glib::RefPtr< Cancellable >&  cancellable  )  const

bool Gio::File::remove (  ) 

Deletes a file.

Returns:
true if the file was deleted. false otherwise.
bool Gio::File::remove ( const Glib::RefPtr< Cancellable >&  cancellable  )

Glib::RefPtr<FileOutputStream> Gio::File::replace ( const std::string etag = std::string(),
bool  make_backup = false,
FileCreateFlags  flags = FILE_CREATE_NONE 
)

Returns an output stream for overwriting the file, possibly creating a backup copy of the file first.

This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.

By default files created are generally readable by everyone, but if you pass FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If you pass in an etag value, then this value is compared to the current entity tag of the file, and if they differ a Gio::Error with WRONG_ETAG will be thrown. This generally means that the file has been changed since you last read it. You can get the new etag from FileOutputStream::get_etag() after you've finished writing and closed the FileOutputStream. When you load a new file you can use FileInputStream::query_info() to get the etag of the file.

If make_backup is true, this function will attempt to make a backup of the current file before overwriting it. If this fails aa Gio::Error with CANT_CREATE_BACKUP will be thrown. If you want to replace anyway, try again with make_backup set to false.

If the file is a directory a Gio::Error with IS_DIRECTORY will be thrown, and if the file is some other form of non-regular file then aa Gio::Error with NOT_REGULAR_FILE will be thrown. Some file systems don't allow all file names, and may throw a Gio::Error with INVALID_FILENAME, and if the name is to longa Gio::Error with FILENAME_TOO_LONG will be thrown. Other errors are possible too, and depend on what kind of filesystem the file is on.

Parameters:
etag An optional entity tag for the current Glib::File.
make_backup true if a backup should be created.
flags A set of FileCreateFlags.
Returns:
A FileOutputStream.
Glib::RefPtr<FileOutputStream> Gio::File::replace ( const Glib::RefPtr< Cancellable >&  cancellable,
const std::string etag = std::string(),
bool  make_backup = false,
FileCreateFlags  flags = FILE_CREATE_NONE 
)

Returns an output stream for overwriting the file, possibly creating a backup copy of the file first.

This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.

By default files created are generally readable by everyone, but if you pass FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

If you pass in an etag value, then this value is compared to the current entity tag of the file, and if they differ a Gio::Error with WRONG_ETAG will be thrown. This generally means that the file has been changed since you last read it. You can get the new etag from FileOutputStream::get_etag() after you've finished writing and closed the FileOutputStream. When you load a new file you can use FileInputStream::query_info() to get the etag of the file.

If make_backup is true, this function will attempt to make a backup of the current file before overwriting it. If this fails aa Gio::Error with CANT_CREATE_BACKUP will be thrown. If you want to replace anyway, try again with make_backup set to false.

If the file is a directory a Gio::Error with IS_DIRECTORY will be thrown, and if the file is some other form of non-regular file then aa Gio::Error with NOT_REGULAR_FILE will be thrown. Some file systems don't allow all file names, and may throw a Gio::Error with INVALID_FILENAME, and if the name is to longa Gio::Error with FILENAME_TOO_LONG will be thrown. Other errors are possible too, and depend on what kind of filesystem the file is on.

Parameters:
etag An optional entity tag for the current Glib::File.
make_backup true if a backup should be created.
flags A set of FileCreateFlags.
Returns:
A FileOutputStream.

const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable,
int  io_priority = Glib::PRIORITY_DEFAULT 
)

Asynchronously sets the display name for a given Gio::File.

For the synchronous version of this function, see set_display_name(). When the operation is finished, slot will be called. You can then call set_display_name_finish() to get the result of the operation.

Parameters:
display_name A string.
slot A callback slot which will be called when the request is satisfied.
cancellable A Cancellable object which can be used to cancel the operation.
io_priority The I/O priority of the request.
Glib::RefPtr<File> Gio::File::set_display_name_finish ( const Glib::RefPtr< AsyncResult >&  result  ) 

Finishes setting a display name started with g_file_set_display_name_async().

Parameters:
res A AsyncResult.
Returns:
A File or 0 on error. Free the returned object with Glib::object_unref().
void Gio::File::start_mountable ( const SlotAsyncReady slot,
const Glib::RefPtr< MountOperation >&  start_operation,
DriveStartFlags  flags = DRIVE_START_NONE 
)

Starts a file of type Mountable.

Using start_operation, you can request callbacks when, for instance, passwords are needed during authentication.

When this operation has completed, slot will be called and the operation can be finalized with start_mountable_finish().

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

Parameters:
slot,: A callback to call when the request is satisfied.
cancellable A Cancellable object.
flags Flags affecting the operation

When this operation has completed, slot will be called and the operation can be finalized with stop_mountable_finish().

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

Parameters:
slot,: A callback to call when the request is satisfied.
start_operation A Cancellable object.
flags Flags affecting the operation
void Gio::File::stop_mountable ( const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable,
const Glib::RefPtr< MountOperation >&  start_operation,
MountUnmountFlags  flags = MOUNT_UNMOUNT_NONE 
)

Stops a file of type Mountable.

Using start_operation, you can request callbacks when, for instance, passwords are needed during authentication.

When this operation has completed, slot will be called and the operation can be finalized with stop_mountable_finish().

The operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, a Gio::Error with CANCELLED will be thrown.

Parameters:
slot,: A callback to call when the request is satisfied.
cancellable A Cancellable object.
flags Flags affecting the operation
bool Gio::File::stop_mountable_finish ( const Glib::RefPtr< AsyncResult >&  result  ) 

Finishes an stop operation, see g_file_stop_mountable() for details.

Finish an asynchronous stop operation that was started with g_file_stop_mountable().

Since glibmm 2.22:
Parameters:
result A AsyncResult.
Returns:
true if the operation finished successfully. false otherwise.
bool Gio::File::supports_thread_contexts (  )  const

Checks if file supports <link linkend="g-main-context-push-thread-default-context">thread-default contexts</link>.

If this returns false, you cannot perform asynchronous operations on file in a thread that has a thread-default context.

Since glibmm 2.22:
Returns:
Whether or not file supports thread-default contexts.
bool Gio::File::trash (  ) 

Sends the file to the "Trashcan", if possible.

This is similar to deleting it, but the user can recover it before emptying the trashcan. Not all filesystems support trashing, so this call can throw a Gio::Error with NOT_SUPPORTED.

Returns:
true on successful trash, false otherwise.
bool Gio::File::trash ( const Glib::RefPtr< Cancellable >&  cancellable  ) 

Sends file to the "Trashcan", if possible.

This is similar to deleting it, but the user can recover it before emptying the trashcan. Not all file systems support trashing, so this call can throw a Gio::Error with NOT_SUPPORTED.
