KoPicture KoPictureCollection::findPicture ( const KoPictureKey key  )  const

Looks for a clipart in the collection, returns a new KoPicture with that key if not found.

Definition at line 35 of file KoPictureCollection.cpp.

KoPicture KoPictureCollection::insertPicture ( const KoPictureKey key,
const KoPicture picture 
)

KoPicture KoPictureCollection::insertPicture ( const KoPicture picture  ) 

Inserts a picture into the collection, if not already there Same as above, but takes the key from the picture.

KoPicture KoPictureCollection::loadPicture ( const QString &  fileName  ) 

Load a clipart from a file (and insert into the collection).

The modification date of the file is checked, to create the key for this clipart. If this key maps to an existing clipart in the collection, then this picture is returned, otherwise the file is loaded.

Definition at line 102 of file KoPictureCollection.cpp.

bool KoPictureCollection::saveToStore ( const Type  pictureType,
KoStore store,
const QValueList< KoPictureKey > &  keys 
)

Save the used picturess from the collection into the store Usually called from completeSaving().

Parameters:
pictureType type for the stored picture
store the store in which to save the pictures
keys the list of keys corresponding to the pictures to save

Todo:
Reduce lameness of dox for pictureType.

QDomElement KoPictureCollection::saveXML ( const Type  pictureType,
QDomDocument &  doc,
QValueList< KoPictureKey keys 
)

pictures/picture1.png) for each picture.

Parameters:
pictureType the type of the collection
doc the DOM document in which the tags are to be generated

Read the <PICTURES>, <PIXMAPS> or <CLIPARTS> tag, and save the result (key<->store-filename associations) into the QMap.

You may want to 'new' a QMap in loadXML, and to use and then delete it in completeLoading (to save memory).

Parameters:
pixmapsElem the <PICTURES>, <PIXMAPS> or <CLIPARTS> element

void KoPictureCollection::readXML ( QDomElement &  pixmapsElem,
QMap< KoPictureKey, QString > &  map
