[Gilles Caulier-4]

SVN commit 816774 by cgilles:

digiKam from trunk (KDE4) : I'm happy to said than a new powerfull Search tool is available in digiKam : Searches over a map !

This tool use Marble widget from trunk with a patch from me to perform a rectangle selection on the canvas. Thepatch is available at this url:

http://digikam3rdparty.free.fr/misc.tarballs/marbleselection.patch

When you make a selection, digiKam query the database to find all pictures which have been taken into this area.

There is a screenshot of this tool in action at this url:

Several improvments need to be done in marble to have a more suitable selection tool, but at least it work fine as well.
