Detailed Description
This is one group of meta information items about a file (see KFileMetaInfo). A group of meta information items about a file.

Constructor & Destructor Documentation
|
Copy constructor.
Definition at line 1061 of file kfilemetainfo.cpp. |
|
Default constructor. This creates an "invalid" item

Member Function Documentation
|
The assignment operator, so you can do: . This will create a shared copy of the object. The actual data is automatically deleted if all copies go out of scope Definition at line 1078 of file kfilemetainfo.cpp. References d. |
|
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).
Definition at line 1091 of file kfilemetainfo.cpp. Referenced by removeItem(). |
|
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?).
Definition at line 1097 of file kfilemetainfo.cpp. |
|
Returns true if an item as added or removed from the group.
Definition at line 1206 of file kfilemetainfo.cpp. |
|
Operator for convenience. It does the same as item(), but you cannot specify a group to search in Definition at line 734 of file kfilemetainfo.h. References item(). |
|
This method searches for the specified item.

|
Returns the item with the given
Definition at line 1180 of file kfilemetainfo.cpp. References QMapIterator::data(). |
|
Convenience function. Returns the value of the specified key. It does the same as item(key).value().
Definition at line 758 of file kfilemetainfo.h. References item(), and KFileMetaInfoItem::value(). |
|
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
Definition at line 1156 of file kfilemetainfo.cpp. |
|
Returns true if this group supports adding or removing arbitrary keys, false if not.

|
Returns a list of all keys.

|
Returns a list of all keys in preference order.

Add an item to the info.
This is only possible if the specified

Referenced by KFileMetaInfo::saveItem(). |
|
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.
Definition at line 1264 of file kfilemetainfo.cpp. |
|
Returns a list of all removed items.

|
The name of this group.
Definition at line 1191 of file kfilemetainfo.cpp. |
|
The translated name of this group.
Definition at line 1151 of file kfilemetainfo.cpp. |

Returns the attributes of this item.
