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.

Definition at line 35 of file kfileitem.h.

Member Enumeration Documentation

The timestamps associated with a file.

  • ModificationTime: the time the file's contents were last modified
  • AccessTime: the time the file was last accessed (last read or written to)
  • CreationTime: the time the file was created

Definition at line 46 of file kfileitem.h.

Constructor & Destructor Documentation

KFileItem::KFileItem ( )

Null KFileItem.

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

Definition at line 510 of file kfileitem.cpp.

KFileItem::KFileItem ( const KIO::UDSEntry entry,
const QUrl itemOrDirUrl,
bool  delayedMimeTypes = false,
bool  urlIsDirectory = false 
)

Creates an item representing a file, from a UDSEntry.

This is the preferred constructor when using KIO::listDir().

Parameters
entrythe KIO entry used to get the file, contains info about it
itemOrDirUrlthe URL of the item or of the directory containing this item (see urlIsDirectory).
delayedMimeTypesspecifies if the mimetype of the given URL should be determined immediately or on demand. See the bool delayedMimeTypes in the KDirLister constructor.
urlIsDirectoryspecifies 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);

Definition at line 515 of file kfileitem.cpp.

KFileItem::KFileItem ( mode_t  mode,
mode_t  permissions,
const QUrl url,
bool  delayedMimeTypes = false 
)

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

Parameters
modethe file mode (according to stat() (e.g. S_IFDIR...) Set to KFileItem::Unknown if unknown. For local files, KFileItem will use stat().
permissionsthe 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.
urlthe file url
delayedMimeTypesspecify if the mimetype of the given URL should be determined immediately or on demand
Deprecated:
since 5.0. Most callers gave Unknown for mode and permissions, so just port to KFileItem(url) and setDelayedMimeTypes(true) if necessary.

Definition at line 522 of file kfileitem.cpp.

KFileItem::KFileItem ( const QUrl url,
const QString mimeType = QString(),
mode_t  mode = KFileItem::Unknown 
)

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

Parameters
urlthe file url
mimeTypethe name of the file's mimetype
modethe mode (S_IFDIR...)

Definition at line 529 of file kfileitem.cpp.

KFileItem::KFileItem ( const QUrl url,
KFileItem::MimeTypeDetermination  mimeTypeDetermination 
)

Creates an item representing a file, with the option of skipping mime type determination.

Parameters
urlthe file url
mimeTypeDeterminationthe mode of determining the mime type: NormalMimeTypeDetermination by content if local file, i.e. access the file, open and read part of it; by QMimeDatabase::MatchMode::MatchExtension if not local. SkipMimeTypeFromContent always by QMimeDatabase::MatchMode::MatchExtension, i.e. won't access the file by stat() or opening it; only suitable for files, directories won't be recognized.

Member Function Documentation

bool KFileItem::acceptsDrops ( ) const

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:
Since 4.0. This logic is application-dependent, the behavior described above mostly makes sense for file managers only. KDirModel has setDropsAllowed for similar (but configurable) logic.

Definition at line 1259 of file kfileitem.cpp.

KACL KFileItem::ACL ( ) const

Returns the access control list for the file.

Returns

Definition at line 1410 of file kfileitem.cpp.

bool KFileItem::cmp ( const KFileItem item) const

Somewhat like a comparison operator, but more explicit, and it can detect that two fileitems differ if any property of the file item has changed (file size, modification date, etc.).

Two items are equal if all properties are equal. In contrast, operator== only compares URLs.

Parameters
itemthe item to compare
Returns
true if all values are equal
