## Detailed Description

This combobox shows a number of recent URLs/directories, as well as some default directories. A combo box showing a number of recent URLs/directories.

It will manage the default dirs root-directory, home-directory and Desktop-directory, as well as a number of URLs set via setURLs() and one additional entry to be set via setURL().

## Constructor & Destructor Documentation

KURLComboBox::KURLComboBox | ( | Mode | mode,
|  | QWidget * | parent = 0,
|  | const char * | name = 0
| ) |

  | Constructs a KURLComboBox. Parameters:
  mode | is either Files, Directories or Both and controls the following behavior: Files all inserted URLs will be treated as files, therefore the url shown in the combo will never show a trailing / the icon will be the one associated with the file's mimetype. Directories all inserted URLs will be treated as directories, will have a trailing slash in the combobox. The current directory will show the "open folder" icon, other directories the "folder" icon. Both Don't mess with anything, just show the url as given.

KURLComboBox::~KURLComboBox | ( |  | ) |

| Destructs the combo box. Definition at line 56 of file kurlcombobox.cpp.

## Member Function Documentation

void KURLComboBox::setURL | ( | const KURL & | url | ) |

| Sets the current url. This combo handles exactly one url additionally to the default items and those set via setURLs(). So you can call setURL() as often as you want, it will always replace the previous one set via setURL(). If `url` is already in the combo, the last item will stay there and the existing item becomes the current item. The current item will always have the open-directory-pixmap as icon. Note that you won't receive any signals, e.g. textChanged(), returnPressed() or activated() upon calling this method. Definition at line 199 of file kurlcombobox.cpp. References QPtrList< KURLComboItem >::append(), QComboBox::count(), QPtrListIterator::current(), getPixmap(), QComboBox::insertItem(), KURL::isEmpty(), KURL::isLocalFile(), KURL::path(), KURL::prettyURL(), QPtrList< KURLComboItem >::removeLast(), KComboBox::setCurrentItem(), setDefaults(), QComboBox::text(), updateItem(), and KURL::url(). Referenced by KFileDialog::readConfig().

void KURLComboBox::setURLs | ( | QStringList | urls | ) |

| Inserts `urls` into the combobox below the "default urls" (see addDefaultURL). If the list of urls contains more items than maxItems, the first items will be stripped. Definition at line 137 of file kurlcombobox.cpp. Referenced by KFileDialog::readConfig(), and KFileDialog::readRecentFiles().

void KURLComboBox::setURLs | ( | QStringList | urls,
|  | OverLoadResolving | remove
| ) |

| Inserts `urls` into the combobox below the "default urls" (see addDefaultURL). If the list of urls contains more items than maxItems, the `remove` parameter determines whether the first or last items will be stripped. Definition at line 142 of file kurlcombobox.cpp. References QPtrList< KURLComboItem >::append(), QPtrList< KURLComboItem >::clear(), QPtrList< KURLComboItem >::count(), KURL::fromPathOrURL(), getPixmap(), KURL::isLocalFile(), KURL::path(), setDefaults(), and QComboBox::text().

QStringList KURLComboBox::urls | ( |  | ) | const

| Returns: a list of all urls currently handled. The list contains at most maxItems() items. Use this to save the list of urls in a config-file and reinsert them via setURLs() next time. Note that all default urls set via addDefaultURL() are not returned, they will automatically be set via setURLs() or setURL(). You will always get fully qualified urls, i.e. with protocol like file:/ Definition at line 81 of file kurlcombobox.cpp. References QComboBox::count(), QPtrList< KURLComboItem >::count(), QString::isEmpty(), and QComboBox::text(). Referenced by KFileDialog::saveRecentFiles().

void KURLComboBox::setMaxItems | ( | int |  | ) |

| Sets how many items should be handled and displayed by the combobox. See also: maxItems Definition at line 281 of file kurlcombobox.cpp. References QPtrList< KURLComboItem >::count(), QComboBox::count(), QPtrListIterator::current(), QComboBox::currentItem(), KComboBox::setCurrentItem(), and setDefaults(). Referenced by KFileDialog::readConfig(), and KFileDialog::readRecentFiles().

int KURLComboBox::maxItems | ( |  | ) | const`[inline]`

| Returns: the maximum of items the combobox handles. See also: setMaxItems Definition at line 135 of file kurlcombobox.h.

void KURLComboBox::addDefaultURL | ( | const KURL & | url,
|  | const QString & | text = QString::null
| ) |

| Adds a url that will always be shown in the combobox, it can't be "rotated away". Default urls won't be returned in urls() and don't have to be set via setURLs(). If you want to specify a special pixmap, use the overloaded method with the pixmap parameter. Default URLs will be inserted into the combobox by setDefaults() Definition at line 101 of file kurlcombobox.cpp. References getPixmap().

void KURLComboBox::addDefaultURL | ( | const KURL & | url,
|  | const QPixmap & | pix,
|  | const QString & | text = QString::null
| ) |

| Adds a url that will always be shown in the combobox, it can't be "rotated away". Default urls won't be returned in urls() and don't have to be set via setURLs(). If you don't need to specify a pixmap, use the overloaded method without the pixmap parameter. Default URLs will be inserted into the combobox by setDefaults() Definition at line 107 of file kurlcombobox.cpp. References QPtrList< KURLComboItem >::append(), QString::isEmpty(), KURL::isLocalFile(), KURL::path(), and KURL::prettyURL().

void KURLComboBox::setDefaults | ( |  | ) |

| Clears all items and inserts the default urls into the combo. Will be called implicitly upon the first call to setURLs() or setURL() See also: addDefaultURL Definition at line 125 of file kurlcombobox.cpp. References QPtrList< KURLComboItem >::at(), QComboBox::clear(), and QPtrList< KURLComboItem >::count(). Referenced by removeURL(), setMaxItems(), setURL(), and setURLs().

void KURLComboBox::removeURL | ( | const KURL & | url,
|  | bool | checkDefaultURLs = true
| ) |

| Removes any occurence of `url`. If `checkDefaultURLs` is false default-urls won't be removed. Definition at line 307 of file kurlcombobox.cpp. References QPtrListIterator::current(), QPtrList< KURLComboItem >::remove(), setDefaults(), and KURL::url().

void KURLComboBox::urlActivated | ( | const KURL & | url | ) | `[signal]`

  | Emitted when an item was clicked at. Parameters:
  url | is the url of the now current item. If it is a local url, it won't have a protocol (file:/), otherwise it will.

QPixmap KURLComboBox::getPixmap | ( | const KURL & | url | ) | const`[protected]`

| Uses KMimeType::pixmapForURL() to return a proper pixmap for `url`. In directory mode, a folder icon is always returned. Definition at line 329 of file kurlcombobox.cpp. References KMimeType::pixmapForURL(). Referenced by addDefaultURL(), setURL(), and setURLs().

void KURLComboBox::updateItem | ( | const KURLComboItem * | item,
|  | int | index,
|  | const QPixmap & | pix
| ) | `[protected]`

| Updates `item` with `pixmap` and sets the url instead of the text of the KURLComboItem. Also works around a Qt bug.
