## Detailed Description

The dir lister deals with the kiojob used to list and update a directory and has signals for the user of this class (e.g. Helper class for the kiojob used to list and update a directory.

konqueror view or kdesktop) to create/destroy its items when asked.

This class is independent from the graphical representation of the dir (icon container, tree view, ...) and it stores the items (as KFileItems).

Typical usage :

- Create an instance.
- Connect to at least update, clear, newItem, and deleteItem.
- Call openURL - the signals will be called.
- Reuse the instance when opening a new url (openURL).
- Destroy the instance when not needed anymore (usually destructor).

Advanced usage : call openURL with _keep = true to list directories without forgetting the ones previously read (e.g. for a tree view)

## Member Enumeration Documentation

enum KDirLister::WhichItems

| Used by items() and itemsForDir() to specify whether you want all items for a directory or just the filtered ones. Definition at line 350 of file kdirlister.h.

## Constructor & Destructor Documentation

KDirLister::KDirLister | ( | bool | _delayedMimeTypes = false | ) |

  | Create a directory lister. Parameters:
  _delayedMimeTypes | if true, mime types will be fetched on demand. If false, they will always be fetched immediately
Definition at line 1512 of file kdirlister.cpp. References setAutoErrorHandlingEnabled(), setAutoUpdate(), setDirOnlyMode(), and setShowingDotFiles().

KDirLister::~KDirLister | ( |  | ) | `[virtual]`

| Destroy the directory lister. Definition at line 1526 of file kdirlister.cpp. References stop().

## Member Function Documentation

bool KDirLister::openURL | ( | const KURL & | _url,
|  | bool | _keep = false,
|  | bool | _reload = false
| ) | `[virtual]`

  | Run the directory lister on the given url. This method causes KDirLister to emit _all_ the items of `_url`, in any case. Depending on `_keep` either clear() or clear(const KURL &) will be emitted first. The newItems() signal may be emitted more than once to supply you with KFileItems, up until the signal completed() is emitted (and isFinished() returns true). Parameters:
  _url | the directory URL.
  _keep | if true the previous directories aren't forgotten (they are still watched by kdirwatch and their items are kept for this KDirLister). This is useful for e.g. a treeview.
  _reload | indicates wether to use the cache (false) or to reread the directory from the disk. Use only when opening a dir not yet listed by this lister without using the cache. Otherwise use updateDirectory.
Returns: true if successful, false otherwise (e.g. invalid `_url`) Definition at line 1535 of file kdirlister.cpp. References emitChanges(), KURL::prettyURL(), and validURL(). Referenced by KFileTreeBranch::populate(), KDirOperator::rereadDir(), and KDirOperator::setURL().

void KDirLister::stop | ( |  | ) | `[virtual]`

void KDirLister::stop | ( | const KURL & | _url | ) | `[virtual]`

  | Stop listing the given directory. Emits canceled() if the killed job was the last running one. Emits canceled( const KURL& ) for the killed job if there are at least two directories being watched by KDirLister. No signal is emitted if there was no job running for `_url`. Parameters:
  _url | the directory URL

Definition at line 1571 of file kdirlister.cpp. Referenced by KDirLister(), and KDirOperator::setDirLister().

bool KDirLister::autoErrorHandlingEnabled | ( |  | ) | const

| Check whether auto error handling is enabled. If enabled, it will show an error dialog to the user when an error occurs. It is turned on by default. Returns: true if auto error handling is enabled, false otherwise See also: setAutoErrorHandlingEnabled() Definition at line 1608 of file kdirlister.cpp.

void KDirLister::setAutoErrorHandlingEnabled | ( | bool | enable,
|  | QWidget * | parent
| ) |

  parent | the parent widget for the error dialogs, can be 0 for top-level
See also: autoErrorHandlingEnabled() Definition at line 1613 of file kdirlister.cpp. Referenced by KDirLister().

bool KDirLister::showingDotFiles | ( |  | ) | const

| Checks whether hidden files (files beginning with a dot) will be shown. By default this option is disabled (hidden files will be not shown). Returns: true if dot files are shown, false otherwise See also: setShowingDotFiles() Definition at line 1580 of file kdirlister.cpp.

void KDirLister::setShowingDotFiles | ( | bool | _showDotFiles | ) | `[virtual]`

  | Changes the "is viewing dot files" setting. Calls updateDirectory() if setting changed. By default this option is disabled (hidden files will not be shown). Parameters:
  _showDotFiles | true to enable showing hidden files, false to disable
See also: showingDotFiles() Definition at line 1585 of file kdirlister.cpp. Referenced by KDirLister(), KFileTreeBranch::KFileTreeBranch(), and KDirOperator::readConfig().

bool KDirLister::dirOnlyMode | ( |  | ) | const

| Checks whether the KDirLister only lists directories or all files. By default this option is disabled (all files will be shown). Returns: true if setDirOnlyMode(true) was called Definition at line 1594 of file kdirlister.cpp.

  | Call this to list only directories. By default this option is disabled (all files will be shown). Parameters:
  dirsOnly | true to list only directories
Definition at line 1599 of file kdirlister.cpp. Referenced by KDirLister(), KFileTreeView::setDirOnlyMode(), and KDirOperator::setMode().

const KURL & KDirLister::url | ( |  | ) | const

| Returns the URL that is listed by this KDirLister. It might be different from the one given with openURL(). if there was a redirection. If you called openURL() with `_keep` == true, this is the first url opened (in e.g. a treeview this is the root). Returns: the url used by this instance to list the files. Definition at line 1619 of file kdirlister.cpp. Referenced by items().

Referenced by openURL(), and KDirOperator::updateDir().

void KDirLister::updateDirectory | ( | const KURL & | _dir | ) | `[virtual]`

  | Update the directory `_dir`. This method causes KDirLister to _only_ emit the items of `_dir` that actually changed compared to the current state in the cache and updates the cache. The current implementation calls updateDirectory automatically for local files, using KDirWatch (if autoUpdate() is true), but it might be useful to force an update manually. Parameters:
  _dir | the directory URL
Definition at line 1713 of file kdirlister.cpp.

KFileItemList KDirLister::items | ( | WhichItems | which = FilteredItems | ) | const

  | Returns the items listed for the current url(). This method will NOT start listing a directory, you should only call this when receiving the finished() signal. The items in the KFileItemList are references to the items used by KDirLister, so e.g. an item gets destroyed when the deleteItem() signal is emitted. Parameters:
  which | specifies whether the returned list will contain all entries or only the ones that passed the nameFilter(), mimeFilter(), etc. Note that the latter causes iteration over all the items, filtering them. If this is too slow for you, use the newItems() signal, sending out filtered items in chunks.
Returns: the items listed for the current url(). Since: 3.1 Definition at line 2104 of file kdirlister.cpp. References itemsForDir(), and url().

KFileItemList KDirLister::itemsForDir | ( | const KURL & | dir,
|  | WhichItems | which = FilteredItems
| ) | const

  | Returns the items listed for the given `dir`. This method will NOT start listing `dir`, you should only call this when receiving the finished() signal. The items in the KFileItemList are references to the items used by KDirLister, so e.g. an item gets destroyed when the deleteItem() signal is emitted. Parameters:
  dir | specifies the url for which the items should be returned. This is only useful if you use KDirLister with multiple URLs i.e. using bool keep = true in openURL().
  which | specifies whether the returned list will contain all entries or only the ones that passed the nameFilter, mimeFilter, etc. Note that the latter causes iteration over all the items, filtering them. If this is too slow for you, use the newItems() signal, sending out filtered items in chunks.
Returns: the items listed for the current url(). Since: 3.1 Definition at line 2109 of file kdirlister.cpp. References QPtrList::append(), QPtrListIterator::current(), KFileItem::isDir(), matchesFilter(), and matchesMimeFilter(). Referenced by items().

void KDirLister::started | ( | const KURL & | _url | ) | `[signal]`
