Detailed Description

A simple wrapper around inotify which only allows to add folders recursively.

Warning: moving of top-level folders is not supported and results in undefined behaviour.

Member Enumeration Documentation

WatchEvent

enum KInotify::WatchEvent

Inotify events that can occur.

Use with addWatch to define the events that should be watched.

These flags correspond to the native Linux inotify flags.

Enumerator
EventAccess	File was accessed (read, compare inotify's IN_ACCESS)
EventAttributeChange	Metadata changed (permissions, timestamps, extended attributes, etc., compare inotify's IN_ATTRIB)
EventCloseWrite	File opened for writing was closed (compare inotify's IN_CLOSE_WRITE)
EventCloseRead	File not opened for writing was closed (compare inotify's IN_CLOSE_NOWRITE)
EventDelete	File/directory created in watched directory (compare inotify's IN_CREATE) File/directory deleted from watched directory (compare inotify's IN_DELETE)
EventDeleteSelf	Watched file/directory was itself deleted (compare inotify's IN_DELETE_SELF)
EventModify	File was modified (compare inotify's IN_MODIFY)
EventMoveSelf	Watched file/directory was itself moved (compare inotify's IN_MOVE_SELF)
EventMoveFrom	File moved out of watched directory (compare inotify's IN_MOVED_FROM)
EventMoveTo	File moved into watched directory (compare inotify's IN_MOVED_TO)
EventOpen	File was opened (compare inotify's IN_OPEN)
EventUnmount	Backing fs was unmounted (compare inotify's IN_UNMOUNT)
EventQueueOverflow	Event queued overflowed (compare inotify's IN_Q_OVERFLOW)
EventIgnored	File was ignored (compare inotify's IN_IGNORED)

Definition at line 38 of file kinotify.h.

WatchFlag

enum KInotify::WatchFlag

Watch flags.

These flags correspond to the native Linux inotify flags.

Enumerator
FlagOnlyDir	Only watch the path if it is a directory (IN_ONLYDIR)
FlagDoNotFollow	Don't follow a sym link (IN_DONT_FOLLOW)
FlagOneShot	Only send event once (IN_ONESHOT)
FlagExclUnlink	Do not generate events for unlinked files (IN_EXCL_UNLINK)

Member Function Documentation

accessed

void KInotify::accessed ( const QString &  file )

signal

Emitted if a file is accessed (KInotify::EventAccess)

attributeChanged

void KInotify::attributeChanged ( const QString &  file )

signal

Emitted if file attributes are changed (KInotify::EventAttributeChange)

closedRead

void KInotify::closedRead ( const QString &  file )

signal

Emitted if FIXME (KInotify::EventCloseRead)

closedWrite

void KInotify::closedWrite ( const QString &  file )

signal

Emitted if FIXME (KInotify::EventCloseWrite)

created

void KInotify::created ( const QString &  file, bool  isDir  )

signal

Emitted if a new file has been created in one of the watched folders (KInotify::EventCreate)

deleted

void KInotify::deleted ( const QString &  file, bool  isDir  )

signal

Emitted if a watched file or folder has been deleted.

This includes files in watched folders (KInotify::EventDelete and KInotify::EventDeleteSelf)

installedWatches

void KInotify::installedWatches ( )

signal

This is emitted once watches have been installed in all the directories indicated by addWatch.

modified

void KInotify::modified ( const QString &  file )

signal

Emitted if a watched file is modified (KInotify::EventModify)

moved

void KInotify::moved ( const QString &  oldName, const QString &  newName  )

signal

Emitted if a file or folder has been moved or renamed.

Warning

The moved signal will only be emitted if both the source and target folder are being watched.

opened

void KInotify::opened ( const QString &  file )

signal

Emitted if a file is opened (KInotify::EventOpen)

resetUserLimit()

void KInotify::resetUserLimit

(

)

Call this when the inotify limit has been increased.

Definition at line 223 of file kinotify.cpp.

unmounted

void KInotify::unmounted ( const QString &  file )

signal

Emitted if a watched path has been unmounted (KInotify::EventUnmount)

watchUserLimitReached

void KInotify::watchUserLimitReached ( const QString &  path )

signal

Emitted if during updating the internal watch structures (recursive watches) the inotify user watch limit was reached.

This means that not all requested paths can be watched until the user watch limit is increased.

The argument is the path being added when the limit was reached.

This signal will only be emitted once until resetUserLimit is called.
