I'm the main developer of Gwenview.

The hand cursor will be removed soon I think. Can you give more details on
the things which are not done the KDE way ?

I guess you're speaking about the image KPart (Gwenview has two KParts, a
file and a dir one). I think this is just a problem of KPart priority: IIRC
it's Konqueror which decides whether it uses a part or start an application
when loading a file. If the setting for XCF is "Open in external app" and
the preferred KPart for JPEG files is KView you will get the behaviour you

Of course if there's some way to keep the same KPart while browsing files,
we would be glad to fix Gwenview.

I started Gwenview because I wanted an image viewer which would show the
current image and the other images of a folder in the same window (You've
got to keep in mind that Gwenview was started in 2000).

I would list the following advantages of Gwenview over KView (in no
particular order):
- Thumbnail view. (current SVN version can show big thumbnails up to
- Support for KIPI plugins.
- Nicer (IMHO) fullscreen mode.
- JPEG comment editor.
- JPEG lossless operations (rotate/mirror)
- Bookmark support.
- The adjust-image-to-window mode is easier to toggle: It's on the toolbar
in Gwenview and will automatically be disabled when clicking on the zoom
toolbar icons. It's a configuration preference in KView, and it renders the
zoom toolbar icons useless.
- Much faster zooming. If I remember well, KView loads images in a QPixmap
and zooms this QPixmap, while Gwenview loads images in a QImage and only
zoom the visible region.
- Brightness and contrast adjustement (this feature needs more exposure,
- Support for External tools.
