This is one item of the meta information about a file (see KFileMetaInfo).

Definition at line 499 of file kfilemetainfo.h.


Constructor & Destructor Documentation

KFileMetaInfoItem::KFileMetaInfoItem (  const KFileMetaInfoItem &    item ) 
 

Copy onstructor.

Definition at line 100 of file kfilemetainfo.cpp.

KFileMetaInfoItem::KFileMetaInfoItem (    ) 
 

Default constructor.

This creates an "invalid" item

Definition at line 107 of file kfilemetainfo.cpp.


Member Function Documentation

const KFileMetaInfoItem & KFileMetaInfoItem::operator= (  const KFileMetaInfoItem &    item ) 
 

The assignment operator, so you can do:.

    KFileMetaInfoItem item = info.item("Title");
 

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 118 of file kfilemetainfo.cpp.

QString KFileMetaInfoItem::key (    ) 
 

Returns:
the key of this item

Definition at line 163 of file kfilemetainfo.cpp.

Referenced by setValue().

QString KFileMetaInfoItem::translatedKey (    ) 
 

Returns:
a translation of the key for displaying to the user. If the plugin provides translation to the key, it's also in the user's language

const QVariant & KFileMetaInfoItem::value (    ) 
 

Returns:
the value of the item.

Definition at line 180 of file kfilemetainfo.cpp.

Referenced by KFileMetaInfoGroup::value().

QString KFileMetaInfoItem::string (  bool    mangle = true )  const
 

Returns:
a string containing the value, if possible. If not, QString::null is returned. if mangle is true, the string will already contain prefix and suffix

Definition at line 185 of file kfilemetainfo.cpp.

bool KFileMetaInfoItem::setValue (  const QVariant &    value ) 
 

changes the value of the item

Definition at line 132 of file kfilemetainfo.cpp.

References QVariant::canCast(), and key().

QVariant::Type KFileMetaInfoItem::type (    ) 
 

convenience method.

It does the same as value()->type()

Returns:
the type of the item

Definition at line 190 of file kfilemetainfo.cpp.

bool KFileMetaInfoItem::isEditable (    ) 
 

You can query if the application can edit the item and write it back to the file with this method.

Note that this doesn't ensure that you have write access to the file and that enough space is available.

Returns:
true if the item's value can be changed, false if not

Definition at line 220 of file kfilemetainfo.cpp.

bool KFileMetaInfoItem::isRemoved (    ) 
 

If you remove an item, it is only marked for removal for the file.

On the next KFileMetaInfo::applyChanges() , it will be removed from the file. With this method, you can ask if the item is marked for removal.

Returns:
true if the item was removed, false if not

Definition at line 158 of file kfilemetainfo.cpp.

bool KFileMetaInfoItem::isModified (    ) 
 

If you change an item, it is marked as "dirty".

On the next KFileMetaInfo::applyChanges() , the change will be written to the file. With this method, you can ask if this item is dirty.

Returns:
true if the item contains changes that have not yet been written back into the file. Removing or adding an item counts as such a change

Definition at line 195 of file kfilemetainfo.cpp.

QString KFileMetaInfoItem::prefix (    ) 
 

This method returns a translated prefix to be displayed before the value.

Think e.g. of the $ in $30

Returns:
the prefix

Definition at line 200 of file kfilemetainfo.cpp.

QString KFileMetaInfoItem::suffix (    ) 
 

This method returns a translated suffix to be displayed after the value.

Think of the kbps in 128kbps *

Returns:
the suffix

Definition at line 205 of file kfilemetainfo.cpp.

uint KFileMetaInfoItem::hint (    ) 
 

Returns:
the hint for this item. See KFileMimeTypeInfo::Hint

Definition at line 210 of file kfilemetainfo.cpp.

uint KFileMetaInfoItem::unit (    ) 
 

Returns:
the unit for this item. See KFileMimeTypeInfo::Unit

uint KFileMetaInfoItem::attributes (    ) 
 

Returns:
the atttributes for this item. See KFileMimeTypeInfo::Attributes

Definition at line 215 of file kfilemetainfo.cpp.

bool KFileMetaInfoItem::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)
