Constructor & Destructor Documentation

KFileMetaInfoGroup::KFileMetaInfoGroup (  const KFileMetaInfoGroup &    original )

Copy onstructor

KFileMetaInfoGroup::KFileMetaInfoGroup (    )

Default constructor. This creates an "invalid" item Since: 3.1

Member Function Documentation

KFileMetaInfoItem KFileMetaInfoGroup::addItem (  const QString &    key )

add an item to the info. This is only possible if the specified key is in the supportedKeys list and not yet defined or if the group supports variable keys.

bool KFileMetaInfoGroup::contains (  const QString &    key )  const

Returns: whether an item for this key exists.

bool KFileMetaInfoGroup::isEmpty (    )

Returns: false if the object contains data, true if it's empty. An empty group is a group with no items (amazing, isn't it?)

bool KFileMetaInfoGroup::isModified (    )

Returns true if an item as added or removed from the group. Returns: true if an item was added or removed from the group, otherwise false. Since: 3.1

bool KFileMetaInfoGroup::isValid (    )

Returns: true if the item is valid, i.e. if it contains data, false if it's invalid (created with the default constructor and not been assigned anything), or if KFileMetaInfoGroup::item() didn't find your requested item)

KFileMetaInfoItem KFileMetaInfoGroup::item (  uint    hint )  const

Returns: the item with the specified hint

KFileMetaInfoItem KFileMetaInfoGroup::item (  const QString &    key )  const

This method searches for the specified item. Returns: the specified item if found, an invalid item, if not Referenced by operator[](), and value().

QStringList KFileMetaInfoGroup::keys (    )

Returns: a list of all keys in the order they were inserted.

const KFileMetaInfoGroup& KFileMetaInfoGroup::operator= (  const KFileMetaInfoGroup &    info )

The assignment operator, so you can do: KFileMetaInfoGroup group = info.group("Technical"); This will create a shared copy of the object. The actual data is automatically deleted if all copies go out of scope

KFileMetaInfoItem KFileMetaInfoGroup::operator[] (  const QString &    key )  const [inline]

operator for convenience. It does the same as item(), but you cannot specify a group to search in Definition at line 729 of file kfilemetainfo.h. References item(), and KStdAccel::key().

QStringList KFileMetaInfoGroup::preferredKeys (    )

Returns: a list of all keys in preference order.

bool KFileMetaInfoGroup::removeItem (  const QString &    key )

remove this item from the meta info of the file. You cannot query KFileMetaInfo for a removed object, but you can query for a list of removed items with removedItems() if you need to. If you re-add it, its value will be cleared

QStringList KFileMetaInfoGroup::supportedKeys (    )

Use this method to get a list of keys in the specified group that the plugin knows about. No variable keys. For a group that doesn't support variable keys, all keys that this group may have are returned. For a group that does support them, the non-variable ones are returned. See KFileMetaInfo about variable keys Returns: the list of keys supported for this mimetype

bool KFileMetaInfoGroup::supportsVariableKeys (    )

Returns: true if this group supports adding or removing arbitrary keys, false if not.

const QVariant KFileMetaInfoGroup::value (  const QString &    key )  const [inline]

Convenience function. Returns the value of the specified key. It does the same as item(key).value() Definition at line 748 of file kfilemetainfo.h. References item(), KStdAccel::key(), and KFileMetaInfoItem::value().
