KoPictureKey Class Reference
#include <KoPictureKey.h>
Detailed Description
KoPictureKey is the structure describing a picture in a unique way.Structure describing a picture on disk.It currently includes the original path to the picture and the modification date.
- Note:
- We use the *nix epoch (1970-01-01) as a time base because it is a valid date. That way we do not depend on a behaviour of the current QDateTime that might change in future versions of Qt and we are also nice to non-Qt programs wanting to read KOffice's files.
This behaviour is also needed for re-saving KWord files having <FORMAT id="2">. When saving again, these files get a <KEY> element as child of <PIXMAPS> but not one as child of <FORMAT> and <IMAGE>. Therefore we need to be careful that the key remains compatible to default values (another good reason for the *NIX epoch)
In case of a remote path, the "original path" is the name of the temporary file that was used to download the file.

KoPictureKey::KoPictureKey | ( | ) |
KoPictureKey::KoPictureKey | ( | const QString & | fn, | |
const QDateTime & | mod | |||
) |
Constructs a key, from a filename and a modification date.
Storing the modification date as part of the key allows the user to update the file and import it into the application again, without the application reusing the old copy from the collection.

KoPictureKey::KoPictureKey | ( | const QString & | fn | ) |
Constructs a key from a filename.
- Note:
- The modification date is set to 1970-01-01
