This is really really great!

I think it would be useful to display the the location of all
found images as small yellow dots in the right world view and use
(e.g.) a red mark for the currently selected image.
Clicking on a dot should make that image the current one.
(What is not obvious: if there are many dots at essentially the same
point, which should be chosen? Google earth has a pretty good
solution of displaying all the possibilities as a cloud around the
chosen point.
However, I am not sure if something like this is possible with marble...)

Another nice thing would be mini-thumbnails as mouse-overs
over a dot. This could be realized using appropriate kml code
in which the (already generated) thumbnail of the image displayed
in a much smaller version.

Yes, it's in my TODO list. the current code already use KML to ask to Marble where to place the picture dot on the map. Currently only one picture mark is supported, but i will improve code. If you is curious, look into libs/imageproperties/worldmapwidget.cpp

Perhaps in the future. New KML import code from marble is currently under construction. Perhaps Torsten can give us more info about...

In all case, is marble can handle mouse click over marks and if a signal is fire from marble, it's easy to use it in digiKam to change iconview focus.

Created an attachment (id=25159)
 --> (http://bugs.kde.org/attachment.cgi?id=25159&action=view)
example kml to show a thumbnail on mouse over

The attached file is an example of how to realize a mouse-over thumbnail
using kml. To test this out:
- edit the two occurances of
  /home/fotos/.thumbnails/large/3869d92528329abd6bc7a34fcc46f1cc.png
  to an existing file in your thumbnails directory
- (optional: adjust  dot_image.png to an existing file with a dot, but
   this is not necessary as GE display a small marker in any case)
- in google earth: add this thumb_mouse_over.kml (with full path)
  as network link to the Temporary Places
- double click on the new entry and it should move you to the location
  of the marker
- now on a mouse over the small thumbnail will be shown
- clicking on that mini-thumbnail will show the thumbnail in larger size
  (including a brief comment).

So to realize this from within digikam, support for
 IconStyle and StyleMap (normal/highlight)
would be needed.
The Region/LatLonAltBox/Lod/LookAt are not needed for this feature.

I just checked with marble: while this file loads fine and
clicking on the resulting point also allows to see the contents,
the mouse-over, the IconStyle and StyleMap is not yet supported.

Torsten, if I remember correctly, further kml features are planned
for post 4.1, is that right? Would IconStyle/StyleMap be one of those?

This is all really great work, Gilles, Marcel and Torsten+the marble team.
Thanks a lot! Arnd

SVN commit 817853 by mwiesweg:

- Correct comment: It's lon1 < lon < lon2 (with positive values to East)
- Searching by a lon/lat rectangle: Handle the case that the rectangle
  stretches the 180 deg longitude line.
  In this case lon1 is suddenly greater than lon2, we can omit checking
  for >180/<-180, so it's (lon > lon1 OR lon < lon2)

Great work Gilles!

But of course ;-), with patch version 5, Qt4.4 and Marble from current SVN I have noticed a few problems:
- usability: I tried hard and had to read the patch to understand I have to use Ctrl+Drag ;-)
- when you drag the rubber band and the scroll-map-arrows at the edge appear, the map does not scroll, and you cannot drop the rectangle there. If you do this, strange things may happen, such as a rubberband that will always follow the mouse cursor from now on in this widget, regardless of click state.
- the found coordinates are printed in the console; if I copy&paste and check the pairs with Google Map, a much larger region is selected than it is shown on map. If I select a small part of Iceland, the West/North coordinates are somewhere on Greenland.
- here, the rubberband is filled with blue noise while dragging and not drawn at all when dropped. I suspect a Qt problem here, or a problem with my system.

I'm sure Gilles will find a more intuitive way. For now it's important that it's technically working.

> the found coordinates are printed in the console; if I copy&paste and check

Yes, the coordinates returned are the bounding box values for the viewport.
Mea culpa - I'll sort that out soon however right now I'm under heavy load for my daytime job.

Multiple points over the map is implemented with commit #818702.

KML import in marble will be improved in a near future. Add mini thumbs over the map will be possible to add new KML sections in worldmapwidget.cpp.
