KFileItem Class Reference

from PyKDE4.kio import *

Detailed Description

A KFileItem is a generic class to handle a file, local or remote. In particular, it makes it easier to handle the result of KIO.listDir (UDSEntry isn't very friendly to use). It includes many file attributes such as mimetype, icon, text, mode, link...

KFileItem is implicitly shared, i.e. it can be used as a value and copied around at almost no cost.

Method Documentation

KACL ACL ( self )

Returns the access control list for the file.

Returns:: the access control list as a KACL

__init__ ( self )

Null KFileItem. Doesn't represent any file, only exists for convenience.

NOTE KDE 4.0 when porting from KFileItem* to KFileItem&: '(KFileItem*)a==0' becomes '(KFileItem)a.isNull()'

__init__	(	self,
		KIO.UDSEntry	entry,
		KUrl	itemOrDirUrl,
		bool	delayedMimeTypes=0,
		bool	urlIsDirectory=0
	)

Creates an item representing a file, from a UDSEntry. This is the preferred constructor when using KIO.listDir().

Parameters:

	entry	the KIO entry used to get the file, contains info about it
	itemOrDirUrl	the URL of the item or of the directory containing this item (see urlIsDirectory).
	delayedMimeTypes	specifies if the mimetype of the given URL should be determined immediately or on demand. See the bool delayedMimeTypes in the KDirLister constructor.
	urlIsDirectory	specifies if the url is just the directory of the fileitem and the filename from the UDSEntry should be used.

When creating KFileItems out of the UDSEntry emitted by a KIO list job, use KFileItem(entry, listjob->url(), delayedMimeTypes, true);

__init__	(	self,
		mode_t	mode,
		mode_t	permissions,
		KUrl	url,
		bool	delayedMimeTypes=0
	)

Creates an item representing a file, from all the necessary info for it.

Parameters:

	mode	the file mode (according to stat() (e.g. S_IFDIR...) Set to KFileItem.Unknown if unknown. For local files, KFileItem will use stat().
	permissions	the access permissions If you set both the mode and the permissions, you save a .stat() for local files. Set to KFileItem.Unknown if you don't know the mode or the permission.
	url	the file url
	delayedMimeTypes	specify if the mimetype of the given URL should be determined immediately or on demand

__init__	(	self,
		KUrl	url,
		QString	mimeType,
		mode_t	mode
	)

Creates an item representing a file, for which the mimetype is already known.

Parameters:

	url	the file url
	mimeType	the name of the file's mimetype
	mode	the mode (S_IFDIR...)

__init__	(	self,
		KFileItem	other
	)

Copy constructor

bool acceptsDrops ( self )

Returns true if files can be dropped over this item. Contrary to popular belief, not only dirs will return true :) Executables, .desktop files, will do so as well.

Returns:: true if you can drop files over the item

Deprecated:: This logic is application-dependent, the behavior described above mostly makes sense for file managers only. KDirModel has setDropsAllowed for similar (but configurable) logic.

assign	(	self,
		KFileItem	item
	)

Deprecated:: simply use '='

bool cmp	(	self,
		KFileItem	item
	)

Somewhat like a comparison operator, but more explicit, and it can detect that two kfileitems are equal even when they do not share the same internal pointer - e.g. when KDirLister compares fileitems after listing a directory again, to detect changes.

Parameters:

item

the item to compare

Returns:: true if all values are equal

KACL defaultACL ( self )

Returns the default access control list for the directory.

Returns:: the default access control list as a KACL

KMimeType.Ptr determineMimeType ( self )

Returns the mimetype of the file item. If delayedMimeTypes was used in the constructor, this will determine the mimetype first.

Returns:: the mime type

KIO.UDSEntry entry ( self )

Returns the UDS entry. Used by the tree view to access all details by position.

Returns:: the UDS entry

void extraData	(	self,
		void	key
	)

Retrieves the extra data with the given key.

Parameters:

key

the key of the extra data

Returns:: the extra data associated to an item with key via setExtraData. 0 if nothing was associated with key.

See also:: extraData

Deprecated:: use model/view (KDirModel) and you won't need this anymore

QString getStatusBarInfo ( self )

Returns the string to be displayed in the statusbar, e.g. when the mouse is over this item

Returns:: the status bar information

QString getToolTipText	(	self,
		int	maxcount=6
	)

Returns the string to be displayed in the tool tip when the mouse is over this item. This may load a plugin to determine additional information specific to the mimetype of the file.

Parameters:

maxcount

the maximum number of entries shown

Returns:: the tool tip string

QString group ( self )

Returns the group of the file.

Returns:: the file's group

bool hasExtendedACL ( self )

Tells if the file has extended access level information ( Posix ACL )

Returns:: true if the file has extend ACL information or false if it hasn't

QString iconName ( self )

Returns the full path name to the icon that represents this mime type.

Returns:: iconName the name of the file's icon

bool isDesktopFile ( self )

Checks whether the file is a readable local .desktop file, i.e. a file whose path can be given to KDesktopFile

Returns:: true if the file is a desktop file.

Since:: 4.1

bool isDir ( self )

Returns true if this item represents a directory.

Returns:: true if the item is a directory

bool isFile ( self )

Returns true if this item represents a file (and not a a directory)

Returns:: true if the item is a file

bool isHidden ( self )

Checks whether the file is hidden.

Returns:: true if the file is hidden.

bool isLink ( self )

Returns true if this item represents a link in the UNIX sense of a link.

Returns:: true if the file is a link

bool isLocalFile ( self )

Returns true if the file is a local file.

Returns:: true if the file is local, false otherwise

bool isMarked ( self )

Used when updating a directory. marked == seen when refreshing.

Returns:: true if the file item is marked

bool isMimeTypeKnown ( self )

Returns:: true if we have determined the mimetype of this file already, i.e. if determineMimeType() will be fast. Otherwise it will have to find what the mimetype is, which is a possibly slow operation; usually this is delayed until necessary.

bool isNull ( self )

Return true if default-constructed

bool isReadable ( self )

Checks whether the file or directory is readable. In some cases (remote files), we may return true even though it can't be read.

Returns:: true if the file can be read - more precisely, false if we know for sure it can't

bool isRegularFile ( self )

Return true if this item is a regular file, false otherwise (directory, link, character/block device, fifo, socket)

Since:: 4.3

bool isWritable ( self )

Checks whether the file or directory is writable. In some cases (remote files), we may return true even though it can't be written to.

Returns:: true if the file or directory can be written to - more precisely, false if we know for sure it can't

QString linkDest ( self )

Returns the link destination if isLink() == true.

Returns:: the link destination. QString() if the item is not a link

QString localPath ( self )

Returns the descriptive comment for this mime type, or the mime type itself if none is present.

Returns:: the mime type description, or the mime type itself

KMimeType.Ptr mimeTypePtr ( self )

Returns the currently known mimetype of the file item. This will not try to determine the mimetype if unknown.

Returns:: the known mime type

QString mimetype ( self )

Returns the mimetype of the file item. If delayedMimeTypes was used in the constructor, this will determine the mimetype first. Equivalent to determineMimeType()->name()

Returns:: the mime type of the file

mode_t mode ( self )

Returns:: the file type

KUrl, bool (local) mostLocalUrl	(	self,

Tries to give a local URL for this file item if possible. The given boolean indicates if the returned url is local or not.

QString name	(	self,
		bool	lowerCase=0
	)

Return the name of the file item (without a path). Similar to text(), but unencoded, i.e. the original name.

Parameters:

lowerCase

bool operator !=	(	self,
		KFileItem	other
	)

bool operator ==	(	self,
		KFileItem	other
	)

Returns:: the permissions of the file

QString permissionsString ( self )

Returns the access permissions for the file as a string.

Returns:: the access persmission as string

QPixmap pixmap	(	self,
		int	_size,
		int	_state=0
	)

Returns a pixmap representing the file.

Parameters:

	_size	Size for the pixmap in pixels. Zero will return the globally configured default size.
	_state	The state of the icon: KIconLoader.DefaultState, KIconLoader.ActiveState or KIconLoader.DisabledState.

Returns:: the pixmap

refresh ( self )

Throw away and re-read (for local files) all information about the file. This is called when the _file_ changes.

refreshMimeType ( self )

Re-reads mimetype information. This is called when the mimetype database changes.

removeExtraData	(	self,
		void	key
	)

Removes the extra data associated with an item via key.

Parameters:

key

the key of the extra data to remove

Deprecated:: use model/view (KDirModel) and you won't need this anymore

run	(	self,
		QWidget	parentWidget=0
	)

Let's "KRun" this file ! (e.g. when file is clicked or double-clicked or return is pressed)

setExtraData	(	self,
		void	key,
		void	value
	)

This allows to associate some "extra" data to a KFileItem. As one KFileItem can be used by several objects (often views) which all need to add some data, you have to use a key to reference your extra data within the KFileItem.

That way a KFileItem can hold and provide access to all those views separately.

I.e. a KFileIconView that associates a KFileIconViewItem (an item suitable for use with QIconView) does

 kfileItem->setExtraData( this, iconViewItem );

and can later access the iconViewItem by doing

 KFileIconViewItem *iconViewItem = static_cast<KFileIconViewItem*>( kfileItem->extraData( this ));

This is usually more efficient then having every view associate data to items by using a separate QDict or QMap.

Note: you have to remove and destroy the data you associated yourself when you don't need it anymore!

Parameters:

	key	the key of the extra data
	value	the value of the extra data

See also:: extraData

See also:: removeExtraData

Deprecated:: use model/view (KDirModel) and you won't need this anymore

setMetaInfo	(	self,
		KFileMetaInfo	info
	)

Sets the metainfo of this item to info.

Made const to avoid deep copy.

Parameters:

info

the new meta info

setName	(	self,
		QString	name
	)

Sets the item's name (i.e. the filename). This is automatically done by setUrl, to set the name from the URL's fileName(). This method is provided for some special cases like relative paths as names (KFindPart)

Parameters:

name

the item's name

setUDSEntry	(	self,
		KIO.UDSEntry	entry,
		KUrl	url,
		bool	delayedMimeTypes=0,
		bool	urlIsDirectory=0
	)

Reinitialize KFileItem with a new UDSEntry.

Note: extra-data set with setExtraData() is not changed or deleted, so be careful what you do!

KDirListerCache uses it to save new/delete calls by updating existing items that are otherwise not needed anymore.

Parameters:

	entry	the UDSEntry to assign to this KFileItem
	url	the file url
	delayedMimeTypes	specifies if the mimetype of the given URL should be determined immediately or on demand
	urlIsDirectory	specifies if the url is just the directory of the fileitem and the filename from the UDSEntry should be used.

Deprecated:: why not just create another KFileItem and use operator=, now that it's a value class?

setUrl	(	self,
		KUrl	url
	)

Sets the item's URL. Do not call unless you know what you are doing! (used for example when an item got renamed).

Parameters:

url

the item's URL

KIO.filesize_t size ( self )

Returns the size of the file, if known.

Returns:: the file size, or 0 if not known

KUrl targetUrl ( self )

Returns the target url of the file, which is the same as url() in cases where the slave doesn't specify UDS_TARGET_URL

Returns:: the target url.

Since:: 4.1

QString text ( self )

Returns the text of the file item. It's not exactly the filename since some decoding happens ('%2F'->'/').

Returns:: the text of the file item

KDateTime time	(	self,
		KFileItem.FileTimes	which
	)

Requests the modification, access or creation time, depending on which.

Parameters:

which

the timestamp

Returns:: the time asked for, 0 if not available
